I have a C6 automatic with the z51 suspension,2009. Since I bought the c6--there is a popping noise coming from above the rear driver's side tire when I make left turns into a sloped driveway. As I come into the driveway, there is one pop when the front tires are up on the apron and a 2nd pop when the rear tires come up on the apron. I also will get this noise when making a left turn where there is a rough road. The rear left sway bar link has been replaced--this did not solve the issue.
Any ideas???
Thanks

Sounds like the bolt in the swaybar link isnt torque properly...replacing the endlink wont fix the issue, it needs to be tightened.

If it is not suspension, you might check the axle nut torque.
If loose, retorque to 118 ft-lbs.
If that is the source of the popping noise, just tightening the axle nut may not make the noise go away. You may need to back off the nut, push the axle in a bit, and lubricate the inner bearing surface and axle spline. Then retorque the nut.

Agree. Make sure all the bolts associated with the swaybar are properly torqued, including where it attaches to the end links. Have a Z51 and swapped my rear swaybar for a Z06, and had exactly the same problem. I re-torqued all the bolts, including the sway bar brackets, and it went away.

HTH. It's worth a try before going further! (And while you are at it, do what Texhawk0 suggested, too)

There was also a problem with a missing weld on the frame just in front of the rear tire during assembly on some cars. I'd say the sway bar link also, though.

I will take all these suggestions to my dealer--after 3 visits-I would just like it fixed.
