spring seat question

[Ian]

my #(*&(#%)&*( rear has been makin noise for like 6 months now, and i could never find out what it is. but, a buddy with a Z28 brought this up today.....

my spring seats up top are fine, they are intact and in fairly good shape.

question is:
Is there supposed to be rubber between the spring and the little cup where it sits on the axle?

[LordoftheBling]

no there is not.

your problem is probally bushings

i wiggled and tried to move everything around back there. my LCA's are lakewood and have urethane bushings. what other bushings could it be, panhard?

[LordoftheBling]

regrease the lca's. spray down the sway bar bushings, and phr

[Ian]

already did all that. my LCA's i actually took off and regreased, just to make sure they werent ****ed up.


grrrrrrrr, its pissin me off.

Make sure the rear sway bar brackets are centered over the tabs on the underside of the axle. If one is off, it will cause the bushing to squeak.

[Ian]

its not more like a squeak, its more like a "thud-rattle"

its not the spare either, and its just on the rear pass. side

If you checked the spring bushing and it's fine I bet it's the shock bushing Ian. These are the rubber pieces that go under and above the mount (under the carpet behind each corner of the rear seat back)

I finally replaced my springs/shocks tonight and when I pulled the stock shocks out of the rear the bushings were nearly falling apart. My spring bushings look great though.

[Ian]

Zahn, theres an upper shock bushing?

Is there a simple way to check it?

[FunkZ]

Yeah, looks almost like an endlink bushing, a solid doughnut-shaped rubber bushing. One goes under the car (on top of the shock) and one goes in the car (on top of the mounting hole).

To check the top bushing you can just pull back the carpet from the side immediately behind the rear seatback. There will be a white foam padding over top of the shock mount. Pull that out and you'll see the top of the shock sticking up through the body. There's a nut, a washer and the bushing on there.

To check the lower half of the top bushing you'll have to remove those top pieces, unbolt the shock from the rearend and it should fall out.

thanks dude, as always

[FunkZ]

Sure thing, if you end up needing one let me know, I think at least one if not two of my old ones were still in good shape.

[LordoftheBling]

i doubt thats your problem. that would be inside the car.. have you made sure your tailights are tight. mine rattle sometime and all it takes is a little tightening and its back to normal.

[Ian]

no, its not an actual rattle sound, its a thudding sound. and damn, its pissin me off.

i cant really diagnose it up here at school, cause my apt. parking lot isnt the best place, but ill see what i can look at when i get home.

[Seppo Kaitainen]

The thudding sound is usually something loose.... Have you changed shocks? If the lower nut on the shock is not torqued enough it'll make a thud sound. Supposily the LCAs make a thud sound if too loose and a squeak when too tight.
