Powetrax lock right issues

I had one in my Dart when I first got it finished retored and I hated the noise. I pulled it out 1 month later and installed a Sure Grip. I was a great unit if you wanted to pull a burnout and have both tires lockup equally the same, but on the street it was a noisy sucker and everytime I would take the car to a local cruise and pull in, people would come up and tell me that there is something wrong with my car because they heard this loud noise coming from the rearend. I got tired of explaining and also the noise.
