Sway Bar Noises

[tb30570]

my 2005 Ion RL's front end suspension makes clunking noises when going over bumps. I'm pretty sure it's front the sway bar system, not the struts. The struts don't leak and when I got it aligned, the mechanic said the struts looked okay.

Does anybody have a list of part numbers I should purchase? Should I go to polyurethane bushings? If I go with polyurethane, where should I buy them? Should I replace the end links? Should I replace anything else while I'm at it?

make sure your bushing mount is still held down, i've been told its a common problem for them to fall out, which minde did

When mine clunked horribly it was the sway bar endlinks.

I got the same problem but its from the bwoody sway bar. So becareful where you get aftermarket stuff from.

I found a few part numbers

sway bar: 15782696
bushings: 15820164
Clamp: 22722387

Haven't found the endlinks yet though

I found more info for the Cobalt. I'm not sure if the Ion has the same front suspension as the Cobalt or not.

Condition #3
Some customers may comment on a clunk/pop type noise coming from the front of the vehicle when driving over rough road surfaces.

Cause #3
This noise may be caused by the stabilizer shaft link ball stud becoming contaminated from moisture.

Correction #3
Inspect the front stabilizer shaft links for damage. To isolate the noise, the link can be also be disconnected from the stabilizer shaft. If the link appears damaged or if the noise goes away when disconnected, replace the link with the revised part.

Hey I noticed you have the ingals torque dampener. When it gets cool out mine pops. Just something for u to think about.

If you do need new end links powergrid makes a nice adjustable piece.

[WSFrazier]

Powergrid endlinks will get rid of the clunking.

If you drag race the car, and not autox/road course. Then you can just get rid of the front sway bar all together.
