Popping noise from front right wheel well

Recommended Posts


I hate to bother everyone, but this issue has defied repair. I haven't tried the dealer yet. I am not sure if they are better but they certainly are more expensive. Here is the issue:

I suspect the car was in an unreported accident. I hear a popping noise from the front right wheel when you turn the wheel tightly. I don't hear it when driving at speed >10 (then again I don't turn tightly above 10; it is kind of a parking lot issue).

First appointment, my german car specialist said that he was over booked but that it was a control arm that he would have to order from porsche. (4 days for parts)

Second appointment, he replaced the control arm: still pops on hard right turns. He said he put the car up and tried hearing the noise while turning the steering wheel: heard nothing. He spun the rotor while up to see if it was something in the rotor/caliper: heard nothing. So to generate the noise, it needs to be on the ground bearing its own weight. He then suggested that it could be the shock. (4 days for parts)

Third appointment, he replaced the shock, bell, stop, cone, bearings, etc. (he said everything except for the spring): still hear the noise. However, he showed me the shock and said that it looked slightly bent to him so this replacement was not a waste. This is after 3 appointments and around at least 1K in repairs. He wanted me to bring it back for a 4th appointment to look at the calipers and the rotors. He suggested that maybe one of the caliper bolts was bent causing it to pop when I turned.

I was told by people at work that it sounded like a CV joint, but that doesn't make sense. I was also told to check to see if the tierod joints are greased/dry. Supposedly a dry tie rod can make noise a popping noise during tight turns. I would love for it to be a $5 fix after everything I have thrown into this.

Any ideas out there? Tie rods? bearings? Other control arm? Anthing I can try to test this and issolate the issue? If nothing else, you all can place your bets and make a game of this situation. Thanks.
