I have an 08 HHR LT. I bought it used and just clicked 108K. I had some noise and bumping and even some squeaking in the winter from the front end.
I have replaced the following: Struts (complete strut kits), sway bar bushings, lower control arms w/ball joints, the control arm stabilizer bars (greasable), hubs and bearings, rotors and brakes. I even put new shocks in the back.
I am still getting a rumbling/bumping noise going over small bumps in the road. Tires are new. I thought this thing should ride like a new car. Does anyone have any idea what it could be? I do not get any noise or vibration from the steering column either. Have I missed something?
Thanks all!

 

Rear hubs? CVs? Tie rod ends?

Maybe the link in my Sig would help, you've already done most of it though.

 

The noise is definitely from the front. I can hear/feel it under or near the front wheels. I don't have any obvious CV noise or issues. I will check the tie rod ends tonight. Thanks.

 

That link covers pretty much every source of suspension noise.

I have an update. After replacing all of the parts I listed above, I still had noise. After a front end alignment, all is well. Drives super smooth, can't feel any rumbling or bumping.
Drives like a new car. Thanks for the input!

 

Like the little forklift in "Cars" said, it just needed a "Peetstop!" to fix it up.

Glad to hear you found helpful info here, and that it's a happy HHR now.



Cripes, nearly forgot the forklift is called Guido, my 2 1/2 year old son would shoot me for forgetting that, especially after watching Cars about 3 million times.
