I found a couple performance shops that work on drag cars in the neighborhood. They narrow rears, so they should be able to handle this. Let's hope so. Waiting to actually get someone to answer the phone. The 7.25 only makes the noise when making a very slow turn, or coming out of the turn and getting straight again. It's kind of a popping noise. At first I thought it might be the bearing but it doesn't sound like it, so I decided not to waste my time on it and got this 8.75. I drove it 13 hours back from Oklahoma and have been driving it back and forth to town for the last 6 months like this. Locking up at 30-40 mph is one thing. Doing it at 65 or 70 I don't know if I could handle.
