Is this a posi,limited slip, open diff, or what? I have it, one wheel spins on dry pavement. Should they both spin after a clutch rebuild. Itjust turned to80K miles yesterday. I am putting in a 4.10 and want a posi. My differential shop has a "cone style" Auburn unitjust rebuilt this weekend for $200. Maybe I should just get that one. I think it would be stronger.

 

yes both tires should spin with the trac loc and arebuild kit is like 80-100 bucks its not that bad of a unit IMO ive never dealt with auburn...you might want to do some searching...

 

trac loc is fords posi unit.
