Hey guys, this is my first time posting and dont know if there is already another thread like this but i would like to ask again. Recently I installed Eibach lowering springs into my 2008 G coupe. Immediately after installation a clunking noise began to be heard on all 4 sides of the car whenever a bump or crack was drove over. I did some research and thought that they might need to be broken in but the sound is still there and is the same. I also have read that sway bar bushings need to be regreased after installation, is this true? any help/suggestions would be great. thanks in advance.

 

Re-greasing can help the bushings from squeaking but clunking is likely something else. Are you positive you're hearing clunking on all 4 corners? Sometimes if its too low or you have bigger tires you'll just rub on the fenders or in extreme cases bottom out and bump the fenders, all are more or less harmless but I really really doubt that's happening from just a spring drop. We need some more info man..

 

take it back to the shop not suppose to have noise for lowering springs

 

I agree. Something went wrong with the installation. I am dropped on eibach's and did not have this issue.

 

they may have forgotten to return the gasket on the strut tower...
been there...

 

Another rare thing that could've happened is that they installed one of those springs upside down. Trust me I've seen it before. Best of luck and let us know if you resolve the issue and what it ended up being.

 

I dont think it has to do with gasket since there's none in the rear. I think it's wrong installation. I bought them used before and never made a single noise.

 

Well in the rear, its very possible they didn't twist them in correctly to mate with the bottom seat position. There's only one way it can be put in and without extra care they may not notice that. Luckily the rear is VERY easy, you can remove the spring by removing 1 single bolt and reinstall yourself. I doubt they would mess up the front, hard to say.

 

Here ya go... another member had the same exact issue and was able to resolve it.

Hey guys sorry for the late reply, we tried to regrease bushings but the clunking is the same. I have my aligement booked for tomorrow and have talked to them and they said they said they will take a look and make sure everything was done right and nothing is loose. Will keep you guys posted, Thanks for the help!

 

Update**
previous owner had installed sway bar endlinka without grease nipples and we swapped them out for new ones and the problem went away. Thanks for the help!

 

Awesome! Really happy to hear you got the situation fixed. Now enjoy your clunk free ride.

 

Had a feeling it was related to the endlinks. Glad to see you found you a solution!
