Check to see if you have fluid leaking before you replace them. Could be something simple like a strut mount making noise. :thumbsup:

You Do not have to change both rear absorbers, but its usually a good idea, because if one is softer than the other your ride quality will be weird.

No fluid leak.i think these shock absorber is filled with gas not oil.
i will check strut mount tomorrow.
What I like to do is grab the rear of the car and lift it up and set it down a couple times to see if I hear any noises.

You could try the push trunk test too, but I'm not sure how good that test is. You push the trunk down quickly and let go and watch to see how many times it bounces. If it keeps bouncing a few times your struts are probably bad or wore out. If it bounces down then stops back at normal location they are probably fine.

that big spongy O-Ring is supposed to help if your shocks bottom out so you dont damage the shock absorber.

That Suspension support (Strut Mount) Is what makes noise 90% of the time.

You sure its your strut? Could be your rear sway bar bushing... If you were sure its the strut, I would check the torque on the mounts and make sure the insulators are in place so that there is no metal to metal contact. Maybe the spongy o-ring was the insulator? or maybe it was a broken boot?

Spongy orange thing? It's the bump stop (labeled as the spring bumper in the pic).

as you can see spring bumper is divide into 5 part,only one part of that came out.
The whole bump stop needs to be replaced then. It's supposed to be one piece with 5 little sections... all connected together.

Ali - Gas filled shocks/struts still have oil in them.

Just get in alignment plan. I have a 3-year transferable one at Merchants Tire. I could go in for an alignment every day if I wanted. ~$200.

You shouldn't need one for the rears.

Before you buy the parts, price out the complete assemblies (all new mount, boot, rubber seat, spring, and strut).

Monroe has them for about $128+shipping. Lifetime guarantee I believe:

KYB lists only the fronts, not the rear assemblies.

Try getting a breaker bar so you have more torque and spray PB blaster on the bolts if you have crap on the bolts. Its stronger than WD-40. If you spray, you should also wait an hour or so before having a go at it.
