I have a 08 hhr ss that im geting alot of suspension noises like when i go over a speed bump it makes a bottoming out sound are when im on rough roads i get alot of popping sounds coming from my suspension i just recently replaced the front struts but no luck. I also have another sound but its hard to describe but its like a constant rubbing sound when im driving over 45 i took it to have it looked at and they said it was a warped rotor on the rear that was making that constant sound i described so i replaced both rotors on the rear and brake pads but it still has the constant rubbing like sound any ideas would be very helpful

 

If the noise is from the rear at speed, then check the rear hubs.
The front noise could be any number of things. Sway bar bushings, LCA bushings, end links etc. Just have to get under there and look to see which one it is.

Fwiw. Using a little punctuation in your post would make it easier to read.

 

Rear hubs!

 

Don't overlook a "hung" or dragging rear caliper.

 

What's the mileage on the SS? And what make/part no. did you replace the struts with?

 

Maybe the other thread tells that tale

Nope, he never followed up on it.

 

Hmmm!

 

The part number on the strut is 339085 and make is KYB excel G strut. I got them off of ZZP and my mileage is 98 thousand

 

One can spend a lot of unnecessary $'s throwing parts at a problem with noises from the front end, unless they properly do a thorough inspection of all the parts that make up the front end.

He needs to check the whole front end such as: sway bar links and bushings, lower control arms, ball joints etc..
