You need a coil spring compressor. There are two basic types: scissor style and the threaded rod style. Both have clamps that go over the coil on opposite sides. You then compress it by tightening the nuts or bolt to take the tension off the strut base and strut mount. Then take off the strut mount and replace strut. This must be done with extreme respect being paid to the tool. A compressed coil spring lets go of the tool when compressed and bad things can happen. The tool can rented at most auto parts. You can make it with threaded rod, nuts, and clamps but remember to use stuff that will hold a good bit of force. I'd guess most strut springs start at 300 lbs/in and you need to compress the spring a good couple of inches.

I need to replace my front struts and coil assembly, but I cant find the one that fits this. can I use the quick assembly strut or is it suppose to be done separately?

the front strut is an outer case that has the coil spring around it and an inner insert which is the king pin and shocky assembly that is attached to the rubber and bearing in the inner guard
to replace , you have to remove the strut from the car then undo the retainer nut that holds the insert in
the insert is a common item and the job can be done inside the hour per side at any accredited front end specialist shop
you will need a front end wheel alignment done after the job
unless you are trained in the procedure , the coil spring will cause injury if not controlled during the procedure

Removing struts for 2003 lexus ls430

Most of the autoparts stores have the spring compressor you'll need. Front & rear have a thru bolt on the bottom, then the strut is secured by one nut at the top into the strut mount which should have a few nuts you have to remove.

The dangerous part is the coil spring that has to be removed. It will shoot off of the strut if you remove the one large nut on the top of the threaded strut rod.

This could really hurt someone!!! The pressure on the spring must be removed, before removing that nut and that's done after the strut assy. is off of the car!

You need to remove it completely with the strut mount, leaving the spring installed. Then, following the safety instructions for using a coil spring compressor, you can remove the spring and transfer the reusable parts to the new strut and reinstall. Leave the spring compressed and just go from the one it's mounted on, to the new one and put it in the exact same position. Look at where the spring is before dissasembly on the old strut.

I suggest a manual, there are details, like making sure the spring is turned properly to fit as it did before removal. Removing pressure on the suspension to be able to savely remove the strut without it binding & such.

I've done a complete car myself in a few hours, but I have all of the tools. Sometimes it's difficult without a HD Impact wrench, to get these parts to break loose, especially the nut on top of the threaded strut rod. A pipe wrench can be used to hold the rod on the old part, since it won't be used again and that will secure the rod as you loosen the top nut.

Be careful, follow the instructions in your repair manual. If you don't have one and you're attempting this type of work, you may want to spend a few $$$ just to have illustrated instructions right there for every step. If you know your cars, have a decent set of mechanics tools and the special equipment required for this task, it's not a difficult job.

good luck

How to convert a 2001 Range rover 4.6 HSE from Air Bags to Shock Struts & Springs. I have replaced the air ride computer and the air bags. Had installed a manual system using switches. the rear air...

This is not a difficult job for a specialist shop used to doing the conversion but doing it yourself is NOT recommended unless you have a hoist, special tools (like spring compressors) and experience of what to remove.
Do NOT go to a dealer to be ripped off. A specialist Land Rover shop will do this job for around $1000 and save you a lot of angst

Hello teri_townsen,

Working on strutscan be dangerous because the spring is under great pressure so caution must beused at all times. Unless you have a suitable spring compressor I wouldrecommend you install complete strut assemblies. They come assembled with all newparts and you don't need to deal with the spring. 1. Remove thethree strut mount nuts from the top of the struts. 2. Raise andproperly support the car on the frame allowing the front control arms to hangfree. 3. Remove tiresand wheels. 4. Before youremove the strut to knuckle nuts and bolts mark the position of the bolts toknuckle so when you reinstall you can keep the camber correct. 5. Remove strutto knuckle bolts. Note: care mustbe taken that no damage to the ball joint or CV axle, so retain the knucklewith a bungee strap or something suitable. 6. Remove strutfrom vehicle. Install inreverse order. Tighten the top threenuts to 30 foot pounds. Tighten the strutto knuckle bolts to 90 foot pounds. Tighten lug nutsto 100 foot pounds. If you are notsure if you kept the proper camber alignment you should have the front endaligned. Again, care mustbe taken at all steps to avoid injury. Regards, netvan

I need to replace the front struts. Is it the same as replacing shocks?

Hello duaine.
No, the procedures are quite different.
The struts on your impala incorporate the coil spring and an upper mount.
The strut is removed as an assembly of these items.
Then the spring needs to be safely compressed by a tool designed for this, the nut taken off the end of the strut, the spring pressure released and then can be taken apart.
You can now buy complete assembly's at some parts suppliers but they tend to be more costly than simply replacing what you need repaired.
If you have any more details you would like to know, leave them in "add comments" and I will answer you.

How do you changer rear struts on a 97 Ford Escort.

Its simple to unbolt them,but then you will need to go to your locale parts house that has a loaner tool program,and get strut spring depressors,with these special tools it is no big problem,Spring depressor fits on coils of spring and will hold spring depressed while you take center nut off and change strut.

Front spring

Raise and safely support the vehicle.
Remove the tire/wheel assembly.
Remove any brackets or sway bar endlinks that may be attached to the strut.
Remove upper strut mount bolts (NOT THE BIG ONE IN THE CENTER) Should be three bolts.
Remove two strut to knuckle bolts and remove the strut.
Remove the top nut of the strut.
Remove the spring noting how the strut mount and other parts are oriented.
Remove the spring compressor.
Compress the new spring and install the new spring with the strut mount and other parts in the same orientation as it was removed.
Reinstall the top nut.
The rest is opposite of removal.
