New Differential
My 2002 4x4 7.3 Excursion has differential issues. The limited slip is really "limited" as in locked up. I have also decided to get a new ring and pinion as the pinion bearing is making a noise and the gears are wearing funny. I was thinking about getting a Detroit Trutrac. What do you guys think? Any others to consider? Thanks.

Personally I would stick with a good limited slip.

Is the Detroit Trutrac not a limited slip? Their website says it is a "helical gear-type limited slip differential".

It's more expensive and made differently. There are the lockers also, maybe someone will chime in with more info on them.

I would think the lockers would be over kill. They can be harsh for on road only. The factory limited slip is a good unit for mostly street use. The clutches do wear out eventually but is serviceable. The trutrac looks well built, and will likely not slip when needed like a limited slip can. Its also a lot more than getting your current one rebuilt.
If your bearings have been worn out for awhile, that will cause bad wear pattern on gears. Gears may still be usable, of course you might wind up with a little whine.
