Anyone have a DIY on the H&R Springs? My main question is about the rear spring? It appears that some of you are removing only the inner lower control arm bolt to replace the spring. Is this correct or do you have to remove the outer bolt, shock bolt, sway bar bolt etc?

Thanks!

MB makes a tool to remove the rear spring. It compresses it on the car and you pop it out. I borrowed one when I did it. A regular spring compressor might work/fit as well.

Thanks Merc, from the info. that I found on the subject it seems that the short cut on this is to remove only the (1) in board bolt on the LCA while having a jack under the arm. Lower the jack, spring pops out, shove new spring in, jack up arm to compress spring and re-install inboard bolt. I'm going to try what I think the process is and see how this works out.

Yes, you can pull the inner control arm bolt and swing it down.

SWEET!! Thank you sir!!

Car is in pieces as we speak, also doing a LTH install at the same time.. WOW what a pain to get the stock manifolds off...

Yes that is exactly what you have to do. GL

what does it look like?
this would save some time

I think that method with the Jack and bolt would be faster. This tool is annoying, it has to be positioned perfectly or you can't compress the spring enough to get it out. Or you put it too high on the spring and then the tool binds up when you try to pull the spring.

I'd pull that bolt and use the Jack.

Thanks Anthony... I wish you had posted your coil overs a week earlier before I had bought my springs.. What kind of car are you going to end up replacing the C with?

Take Care!!

This is great info.
So nothing from the top (behind the rear seats) needs to be touched?
Can all be done from underneath?

Jasonoff

Nope
Yup

AMG893

That being the case, are the fronts as easy?

Jasonoff

Easy to pull but the springs are a pain to compress.

This type of compressor is useless. Use the clamp plate type.

AMG893

Ahh, ok.
So for the fronts i will need spring compressors for sure.
cant do like the rear and just drop the same part on the front with the jack underneath it?

Jasonoff

Front is a strut assembly. The spring is under load so you need to compress it to pull the top hat off.

EDIT: top hat not had lol

abcut973

^ You'll need a compressor in the front for safely remove the springs in order not to receive it in your face when removing the top hat. And as well to reinstall the top hat on the new springs.
In the back you'll only have to work in the trunk area only if you want to change the shock absorber (in case of coilover install for example).

It looks like the exhaust is removed from Jasonoff's picture. Can this be done without taking the exhaust off?

Jasonoff

Yes, the right side was still in place. Left side was removed to pull the diff.

How long it takes for new springs to settle down after installation ?
Thanks
