This is on a 94 Z. The guy I got the car from just replaced all the lower A arm bushings and all the ball joints and both wheel bearings. when I back up and have the wheels turned like backing out from a parking spot it will pop in the passenger side. It does it a little on the drivers but not as much. I have tried to find what it is going on three days now but can't find anything. Really what else is there that would make this noise? It doesn't do it at all driving down the road.

 

maybe your wheels are rubbing on the inside of the fenders (aftermarket wheels) cause mine do . but again I'm no expert. hope it helps

 

you check tie rods?

 

well i finally figured it out. I tore the entire front suspension out and looked at everything, put it back togethor and it still did it. I finally removed the brand new wheel bearings hub assemblys and put my old ones back and no more popping. I bought a pair of wheel hub assemblys off ebay brand new and they must be just cheap crap. They spin quiet but I'm guessing when they get some side pull on them from turning they must bind up. Who would of thought.
