I had the top mounts replaced over a year ago and am hoping they were fitted correctly.

Suggestion

I'm planning on replacing the H&R springs with a full coil over set to try and eliminate the strut bearings altogether, but I was curious if anyone running H&R springs had noticed increased wear of their strut bearings.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

11 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Hi all. Am having a bit of trouble with the front struts on my car. It would appear the piston portion is seizing/graunching actually making a cracking kind of noise as it turns, to the extent that it undoes the nut on the top!! I had the top mounts replaced over a year ago and am hoping they were fitted correctly. Anyone heard of this before? TIA

POST 2Original post

Upper strut bearings are seized. Disassemble the strut, compress spring, replace the upper strut bearing. Replace top locknut on strut and torque correctly.

POST 3 / ORIGINAL POSTEROriginal post

Oh right, so the bearing doesn't come with the mount?

POST 4Original post

Not that I am aware. See parts diagram here: http://www.autoatlanta.com/porsche-p...section=402-00 Just suggesting you look into this part.

POST 5 / ORIGINAL POSTEROriginal post

No bearing listed that I can see. I am however, not the sharpest tool in the toolbox!!!!

POST 6Original post

There is a flat type bearing under the top mount the whole strut swivels on. I replaced mine when I rebuilt the front struts. I'll try to find a better diagram and part number.

POST 7Original post

Look here : # 11 http://www.autoatlanta.com/porsche-p...section=402-01 I believe the one Joe listed is for the C2

POST 8Original post

Pelican Technical Article on the strut assembly: http://www.pelicanparts.com/techarti...nd_Springs.htm Dporto got to the correct part's listing.

Brilliant, thanks guys. Will get those changed. Sounds far cheaper than new shocks!!!

POST 11Original post

Quotes source post: 12697835

Hello all. Long time lurker, first time poster. I recently had the same issue with the strut bearings on my 1999 C4. PO had a set of H&R Street springs installed, and it seems to have aggravated the issue. However, in addition to the bearing noise, when I turn almost to lock in either direction there is a *pop* that continued even after the bearings were replaced. My indy put it up on the lift and we noticed that when the front wheels are turned the angle that the spring interacts with the top perch increases until it gets to the point where it actually pops. I've been digging through the archives here and I haven't seen anyone else using the H&R Street springs with that complaint. I'm planning on replacing the H&R springs with a full coil over set to try and eliminate the strut bearings altogether, but I was curious if anyone running H&R springs had noticed increased wear of their strut bearings.
