So, every time I leave my garage, go over a bump, go on a bad road, or even sometimes make a turn i hear this constant knocking / clunking noise. Seems like any time the car has a side-to-side motion, I get this noise.

The car has the Hotchkis front / rear sway bars, KYB struts and Eibach springs. The rear endlinks are aftermarket ... but i forget the name. I THINK they are SPL endlinks (they are orange.) The front endlinks are stock, never changed. This is a problem i've been having for the past few months, but i finally tried to find the source of the problem today, with no luck. The noise started after lowering the car, but not immediately... about a month later.

Anyone have any ideas? I checked all the bolts today, endlinks are tight, nothing is visibly loose or broken. I feel like it HAS to be something related to the sway bar / endlinks but at this point I just can't figure out what's causing it. I also can't even pinpoint it to the front or the rear, all i know is it's coming from the passenger side of the car.

 

Lube the sway bar bushings lately?

 

A few months ago, yea. That's a whole other problem though. The bars have been on since like 2010, so now the nipple things for adding grease are totally just clogged up, beyond repair. I have to detach the brackets and add grease that way.

I also read some other stuff online saying you're supposed to extend the front / rear endlinks to remove preload from the bar... I never did that, and mine are still stock length so maybe that could be causing a noise too?

 

First thing I'd check is the front end link. I have Eibachs, Hotchkis sways, exact issue. The front end only makes a small clunk when going over bumps and stuff.

 

I'll check it. I took off the wheel and tried to move the endlink around to see if it had any play, but I didn't actually remove it completely and look at it. It's possible it's gone bad.. 102k miles on the car and that's still the factory end link.
