How To Guide

Disclaimer:
This guide was done myself on my own car. I do not work at a garage and have only learnt how to do this job through experience. It is aimed at enthusiasts willing to do the dirty work themselves and avoid those hideous labour charges. Do not attempt any work upon your car without understanding fully what is involved. Never attempt anything without making sure you know exactly what you are doing and that you have the correct tools. Never endanger yourself or others through in-propper use of tools and the lack of safety equipment. I am stating now that any damage done to yourself or your car while using this guide is 100% your fault and if you dont agree then stop reading now.

On a lighter note I am more than happy to help anybody with questions and offer advice.

Please only comment with constructive criticism or appraisal. I have already stated I am not garage trained.

Recommended Equipment

Allen Keys
Spring Compressors (The 2 hook type are better)
15mm Deep Offset Spanner. ( A must for any puma with interior )
Trolley Jack
Axle Stands
Socket Set
Impact Wrench (Would make things a lot easier)
WD40
Copper Grease (Would advice)
Various Other basic Tools like screwdrivers and pliers may come in handy
Mole Grips (a MUST)
Torque Wrench (if torque settings are known then use one)
Mallet
Assorted Spanners

Step by step guide to changing suspension.

This guide shows you how to fit aftermarket coilovers to your puma.

This guide could also help when fitting springs and dampers and/or repairing original suspension.

I fitted AP Coilovers bought through AP's own website which directs you to Venom Motorsport.

They cost me £422 and I bought the ones with a fork mounted rear end.

97 > 99 Pumas have an axle with fork mountings and the pumas made from then on have an eye mounted rear setup.

Those with eagle eyes will notice my Puma was made in 2000 and but has a older axle. This was due to another suspension issue I covered within my project thread.

Ok lets start.

I will start with the back suspension as its the easiest but before you touch that jack remove the locking wheel nuts off all the wheels. You will thank me later.
IMG_6390.jpg


Ok so now thats done you can start jacking the car up.

Place the trolley jack at either end of the rear axle (NOT in the middle) and pump it up to its maximum. You need the rear axle to move freely so I use the jacking points on the sills to put my axle stands. I like to use a thick layer of padding ( I use towels ) to protect them a little and help spread the load.

Repeat on the other side of the axle to have the end hanging in the air on axle stands. You may want to wedge something infront of the front wheels to stop them moving but if you are on a flat surface I wouldn't be too worried about this.

TIP Once the rear end is jacked up place the trolley jack under the axle in the middle but without any weight being taken. This will benefit you later.
IMG_6391.jpg


Undo all the wheel nuts on the back 2 wheels and remove the wheels.
This is what you will be left with.
IMG_6392.jpg

As you can see thats not standard suspension but its very similar. They are just sports dampers and springs. The same will apply to your original suspension.

Now open you boot and pull back the boot carpet revealing the strut tops. To my knowledge the later pumas have huge black brackets obstructing any tools from entering and this is where you will need you deep offset spanner. My puma has no interior so its easy for me but I have done this job before and without it I really struggled.
IMG_6393.jpg


Attach a set of mole grips onto the damper (tight). On the original suspension you may have to cut away at a dust cover to gain access.
IMG_6394.jpg


Now start unbolting the top of the suspension. It will move quickly at first before the mole grips clash with the arch lining but then will go stiff. Make sure your damper isn't spinning in the mole grips. If it is then make them a tiny bit tighter until it doesn't.
IMG_6395.jpg


Once the bolt is removed then repeat on the other side.
IMG_6396.jpg


Ok time to go under the car.

You need to remove the bolt holding the bottom of the damper in.
IMG_6397.jpg


This may need some WD40 to loosen it up and also an impact wrench would come in handy as on your drive leverage is not easy to achieve.

IMG_6398.jpg


Once these bolts have been removed from both sides you can lower the axle using the trolley jack. Don't remove the trolley jack or the drums will smash into the floor plus its hard to lift it evenly without it.

The struts should just lift out now.
IMG_6399.jpg


The only thing you need from the rear struts to my memory are the top mounts but sadly they are a pain to get off due to having a metal ring in them that stops them from sliding off.

For this you will need to compress the springs down and release the pressure on the top mount to remove the metal clip.

WARNING
The tension in springs is so much that if you don't handle them with care they could kill you or others. Please take extra care when handling springs and when compressing them down. Make sure the spring compressors are securely on before tightening and also make sure you tighten them evenly in steps.

Once the pressure has been released off the rubber top mount you can get a screw driver underneath the top metal ring and remove it.
IMG_6402.jpg

IMG_6403.jpg


this will allow you to remove the rubber top mount
IMG_6404.jpg


So you don't lose it I replace it back onto the strut and start removing the pressure off the springs very slowly and evenly. This will leave you with a dismantled damper and spring setup.

IMG_6405.jpg


Time to start fitting the new coilovers. I know thats what you have been waiting for but sadly you need to get them dirty before they go on. This will benefit you later once they have rusted a little and don't seize.

First thing to do is remove the locking pin off the new coilovers.

this will require a small allen key and If I was you I would remove the pin completely and put it somewhere safe.
(if you do lose it then don't worry. Use a Jubilee clip under the adjustable base to stop them winding down under pressure)
IMG_6406.jpg


The bolt on the top of the strut will not be screwed down due to having a plastic locking piece but if it is don't worry just unscrew it take off the springs. If it is screwed down then you will have to get the mole grips out again and attach them to the damper. Coilovers don't have as much pressure in the springs so they shouldn't be much of a danger but still be careful when releasing the pressure. If you are worried about this then screw the adjustable bottom plate to the very bottom and if the springs still haven't released all their pressure then get a friend to remove the bolt while you push on the top plate of the coilovers to compress them. Then release slowly.

IMG_6407.jpg


Once the top plate, springs and gasket piece have been remove (you can leave the bump stop on)
wind the adjustable bottom piece to the very top and probably off the top so it comes off the strut.
IMG_6408.jpg


This is where you need the copper grease. Cover the whole of the strut where the adjustable plate is moving on with a healthy amount of copper grease.
IMG_6408.jpg


Screw the bottom plate all the way to the bottom so that the grease gets in all the cracks and then start assembling the coilover back together.
IMG_6409.jpg


It goes:

TOP
-Bolt
-Rubber Mount
-Top Plate
-Helper Spring (Smaller spring)
-Gasket
-Main Spring (Big Spring)
-Adjustable Bottom Plate
BOTTOM

While the bottom plate is at the bottom you need to screw the top bolt down to the bottom of its thread.

Attach the mole grips onto the dampers and screw it down. I struggled to do this without an impact wrench and even my snap on cordless one struggled to do it unless I did it in pulses to stop the damper spinning.

Once this is tightened down you can start adjusting the bottom plate up to the ride height you required. Find out how far the coilovers allow you to drop the ride height and then measure it from the bottom of the struts threaded bit upwards and deduct that off the lowest ride height. I think mine was 40mm raised from the bottom as a base height. Don't forget that they settle in after a few miles of use so if it looks rather high when back on the car don't panic.
IMG_6411.jpg

IMG_6410.jpg


Repeat on the other coilover.

Time to fit to the car.

Push the coilover up into the top of the chassis and then lower onto the axle so it lines up with the hole for the bottom bolt.

TIP: Copper grease all bolts that are going back onto the car to stop you having to scream at them next time you come to take these bolts off.
IMG_6412.jpg

This is how they will sit
IMG_6413.jpg

IMG_6414.jpg


Before you can raise the axle you need to make sure the top rubber mounts lug in the correct position. The lug needs to be facing directly away from the car. If you look up at the chassis mount you will know what I mean. They should just spin around without too much grief but having the strut bolted down helps you.
IMG_6415.jpg


If you are happy with the struts ride height at this stage then make sure the bottom plate's locking pin location is facing you and then insert the locking pin and tighten. This means you can always adjust the ride height by only having to take the wheel off.
IMG_6416.jpg


Slowly raise the trolley jack which will lift the axle. Keep checking the coilovers aren't getting snagged and they seat properly

IMG_6417.jpg

IMG_6418.jpg


Once they are seated and the trolley jack is securing them up into the chassis you will notice a small problem that I didn't come across when I was using springs and dampers.

With the top bolt on you can't put the top mounts and original top bolts back on to secure the coilovers to the car due to there not being enough thread on the coilover. To get over this I removed the bolt with the coilovers still being secured by the trolley jack using a set of mole grips again before putting the top mount on and securing the bolt down again. Can anyone shed some light on this situation as I am not 100% sure it is correct but it keeps it secure before I can goto the garage and ask them. I think I need some slimline bolts which may of come off the original suspension but seeing as I don't have them any more I didn't have them.

IMG_6419.jpg

IMG_6420.jpg


After that all you need to do is refit the interior and put the wheels back on. Jack the car up from the sides of the axle again and remove the axle stands. Then Lower back down.

IMG_6421.jpg


Thats it for the back. Right I have spent too long writing this so I will do the fronts another day. Enjoy.

I have a feeling I need a slimline bolt for those rear coilovers so dont follow this guide just yet. I am going to fix the problem then re write the last bit.
 
Haven't read any of this yet Chris but judging by all the pictures it's gonna be a damn good guide. Thanks mate ;)

EDIT:- Just had a quick read and I'm sure I read somewhere about the problem you had but it was a while back. Anyway, I vaguely remember it was solved how you did it i.e. remove the top nut on the coil, fit the cup then refit the top nut. Hoping someone else confirm's this or you find the correct solution.

I also read in a thread you answered that the Weitec's came with the half nut, This sound's easier with the half nut but I'd rather find out if what you've done with the AP's is indeed the correct way - which I think it is as it's very logical to use the coilover nut above the strut cup ;)
 
Totally agree- Almost a Idiots Guide to fitting rear coilovers- Great work Chris
 
yippie, you on about the fronts where you dont get enough of the thread through with the early style anti vibration weights?

2 answers to this, either sack the weight off and just use the metal cup, or get the revised later weights, they are only 6 quid each, then you get rid of the metal cup aswell and just have the weight which allows the proper amount of thread through
 
this is right, when the shocks where done on stacey's R reg, we needed to get different caps for the tops :)
 
see this is what I can't understand.

I have had weitec coilovers for over a year and didn't use any weights. Just sacked them off and used the top cup but the weitecs had slim nuts to hold them together and then the top cup and then the final bolt. This is what I am going to do to mine in about 30 mins.

The backs are where I am struggeling. Before they used have little metal rings holding them together including the rubber top mount.

The problem is that the coilovers have no groove for metal rings and I have no slim line bolts that fit off the old or new suspension to hold it all together before it goes on he car. scuba steve do you have any idea what you did?

I am really confused about this as I believe it is knocking from the back because they are not secured properly.

Can you PM me your number so I can ring you as I am working on it now.
 
yeah the weights with top cups underneath are the old style the newer style ones have the top cup and the weight all in one, and leave plenty of room for the thread
 
the rears were fun, trial and error we got it wrong the first time and too much thread poked out the top, even when done up all the weay there was still up and down play in the coilover.

You dont reuse those metal circlips btw, i cant remember the exact order but concentrate on the position of that metal shim that comes with the ap coilovers, getting that in the right order so theres just the right amount of thread poking through.

You only need the rubber top mount off the old stuff
 
u are my saviour! coilovers ave been causing me major problems! but see where the garage has gone rong. cheers v much :eek:k:
 
do not follow yet it isnt complete.

Im confused about the back and have been on the phone to venom motorsport to find out what to do. a few people say you need the circlip and scuba steve you say you dont lol.
 
So with the Weitec's there will be no problem's Chris. i.e. they fit straight on with no pi$$ing about.

Also Steve, you said 'newer style' cups, as mine is an 02 reg does this also mean that I may have no problems with them.

To summarise:- do I need to buy new cap's or half nut's or will my car have the correct cup's and Weitec's will negate the need for the nut's.

Was hoping to hear about the cheap weitec's but look's like they were sold. Were only £100 so look's like I missed the boat dammit...lol.

Come to think about it, I suppose I should just get off my arse and buy them and try fitting them...lol.
 
lol yeah sounds about right paul.

there will be half nuts on your original front suspension to my knowledge.

steve reckons he got half nuts with his kit and I did not so I am going to buy some tomoz and carry this guide on.

I dont have a clue wether the weitecs will work with the old style or new style cups as iv only fitted the ap's


you can tell if yours or old or new style by when you remove them the old style weights have a metal cup seperate underneath them, the new style dont its all one unit
 
Crapping hell, just started doing mine and it's a bitch to get to the top nut on the rears!! You were right about the brackets.

Looks like it'll be a lot easier if I strip the parcel shelf side pieces, the brackets and the rear door cards which is gonna add a fair bit of time to this job as even using an offset spanner looks to be a difficult proposition...dammit, dammit, dammit.

Think I might have to plan this one for the near future and sort my bearings first then strip what I can and see what sort of time I have left today. :(
 
take the side plastics and the seat belt brackets off and you can get to them

its not that time consuming, probably adds about 30 mins if that
 
Gonna do them another time as I've just fitted the new drums, bearings and shoes.

Any idea if the handbrake is self adjusting?...as I wound the adjuster well in so the drums would slide on easily and I currently have no handbrake even after a canny few times of pulling the lever on and off :?
 
the foot brake is what adjusts the self adjuster, in theory when you have them on press the footbrake 5 times or so and it should self adjust
 
Just been out, was tugging on the handbrake lever continuously while driving...lol.

Done about 10 miles of round town driving and the handbrake has slowly got stronger and stronger so I'm happy now.

Thanks for the info, I'll know to stop tugging my lever so much in future....lol
