Whats could be wrong with my car


Asked by Jul 21, 2016 at 07:39 AM about the 2003 Pontiac Grand Prix GT

Question type: Maintenance & Repair

I have a 2003 Pontiac grand Prix, which is 13 years old. It makes a loud knocking, squeaking  noise in the rear while driving. I hear it mainly on the left drive side. I also can feel the knock when i turn left. I just replaced the left side hub, so I know that it's not it. Please can someone help!!!!

Could be a worn rear strut or spring, stabilizer bar bushing, exhaust hanger, etc.

Does it cut out when Turing left?


I agree with Tom. Most likely your rear struts. If you replace them, replace them both, not just one. There's not much else back there so it shouldn't be too hard to find the problem.


Thanks for your advice, but my lugs weren't put on tight enough.
