    D3 Competition Springs Problem

    Not saying this is D3's issue with their springs but likely the shop i got them installed at. I realize I need to bring it back to the shop and i have called to notify them...they seem to not know what it could be

    There is alot of croaking and squeaking at low speeds over every little bump.

    Anything you guys can suggest as it is quite annoying?

    Is something not installed properly? i would think it has nothing to do with any sort of lubrication etc... as it is a suspension component.

    I have installed lowering springs on many cars before and never had an issue with this...

    Thanks

    I installed Eibach's on mine and got the same squeak you are talking about off and on for about a month and then it went away. I even went as far as to take the shocks back out and re-seat the spring in the rubber, but it didn't help.

    Did they change the rubber mounts or keep your old ones? This could very well be the issue. Maybe try spraying some silicone lube up there before it drives you too crazy.

    Total known issue IMO. You need to have the dust caps removed and cut the bump stops that sit in top of the strut. Don't have a pic handy but you cut where the bump stop has a deep wide groove. I've had their springs on mine for 2 years and it has been quiet. Also some put sleeves around the springs up top. Do a search and I'm guessing you can find a detailed procedure.

    The black "dust cap" that clips on to the actual shock housing is the issues. The upper bump stop is a red herring IMHO - but cut it anyway.

    And double-triple check each bolt and nut for tightness. I also suspect that we're collectively killing our swaybar end links, as they will rotate and change orientation on removal/reinstall, changing the wear pattern. Whether this "settles" in or not remains to be seen.

    In either case, the black dust cap serves ZERO purpose and should be removed.

    Hello '84
    …Don't want to hijack the thread, but your comment on the sway bar end link wear problem sounds like important info. Where is the wear showing up… on the bar ends or the link ends?
    What is the fix? Would an after market bar and adj. links be of help? Thanks.

    So you have the competition springs, or their lowering ones? You used both terminologies.

    I've had the competition springs since last year, and haven't had any issues. I thought that it was just their lowering springs.
