9" TracLock Limited Slip Rebuild

[olddog]

I think I have a TracLock carrier. It has clutches in it. I'm looking for information on how to determine what might be wrong with it and how to rebuild it. Like what to measure. How can I tell if the clutches are worn?

The reason I pulled it, is that I started to feel it locking and unlocking. Worse than a chatter. Almost like a clunk. I first noticed it when I backed up after setting a few days. Then this fall, it started doing it on right turns, with light power to it. Step down on the gas and it would quit. Within another 25 miles, it started doing it turning left or right. I even felt it coming to a stop sign on a straight stretch. Just pushing it in the garage, as soon as you start a turn you can feel the car clunking.

I don't really see anything wrong with it. The spider gears look good on the sides where they touch. The tips of the gears, where they do not touch anything, have faint lines. Perhaps machine lines from manufacturing, but not sure.
