I think the reason mine chatters when cold/turning is becasue my car will "sit" sometimes for a month or more without moving and the clutch pac will "try out" causing the clutches to not dis-engage right off....once driven a few miles and warmed up, it works correctly with no chattering...
This may not be accurate,and if it's not,someone please correct me, but years and years ago,an old Ford mechanic told me the Ford factory trac loc rear was designed with the clutch pac to have some "slip" in it, and when one wheel spins 1.5 rotations, the clutch pac should engage and apply power to both wheels......
A lot of drag racers would rebuild their clutch pac and stretch the springs or add shims to tighten it up to act as a locker for drag racing. this may be o-k for a dedicated drag racer, but that's all it's good for, not good for street driving...
Setting up a unit too tight will only make the clutches wear out faster than normal.......
Mine as 115,000 miles all total on the original unit with only oil changes every 10 years or so. I took the 3rd member out of my daddy's F-150 when it had 85,000 miles on it and only changed the ring/pinion gear and put it in my car and it's still works perfectly to this day...
