I had the 10-Bolt 7.5" rear in my 92 rebuilt.

List of parts:
Detroit Tractech limited slip (posi)
Moser 28 Spline axles w/c-clips
3.73 Gears
Summit Racing aluminum differential cover
Sythetic fluid

Now for the issue(s):
When the car is at speed or speeding up, it all sounds good! When the car slows down to about 1500rpm (just let off the gas), there is noise from the rear of the car. It sounds like the carrier has extra play in it. The same sound occurs at low speeds and turning. You can also hear it when the brakes are pressed to slow down.

The car takes off very well and nothing slips. While I do not think there is anything loose or broke, I am concerned the Detroit Tractech may have some issues. This sound is hard to describe.
