My 2001 Suburban 2500 has a noise in the front that my mechanic cannot find. After Backing up while turning (i.e. backing into a parking space), There is a pronounced "POP" when the steering is returned to center and the truck moves forward. Ball joints, tie rods, steering box, sway bar bushings, etc. all OK. Replaced upper driver's side ball joint. All others OK. No driveability issues. Just annoying POP. Any ideas?

 

front axles? CV joints?

 

Yeah Im thinking something with the steering linkage, possibly wheel bearings...

 

have them check your sway bar link kits

 

Thanks for the reply. It is 2wd. Both wheel bearings are new. Will have sway bar link kits checked. Don't know whether they checked that or not. I do some of my own work so is there a visual or other check I might be able to do?

 

Something else to consider/check is motor and transmission mounts...try to push up on the trans tail-stock and see if you can see any separation or cracks
