Hauled the camper up to the hills last weekend to go huckleberry camping. On tight to not so tight corners i'm getting a huge pulsating grind coming from the rearend of the truck. I have always felt a grind when I'm loaded and turning tightly on asphault or concrete but not near this bad and not with pulsation. This weekend I was on loose gravel and dirt and still got the bad grinding.I just assumed I had posi. because of the grind on dry pavement and in the winter the diff stays locked no matter what. In fact I've come close to wadding the truck up a few times as a result. I also go through rear tires like mad, which I thought was a diesel torque thing. Now the questions. Has anybody experienced this and what did you find? How do ID what type of diff and gear ratio? I've only seen 3.55's and 4.10's on the web, I can measure approx with tire/driveline spin calc. What is the general feedback from eaton detroit trutrac diffs. If I have to replace mine I was thinking of going that direction.I'm headed to my shop to start tearing into this problem. Thanks for any input. Bret

I can't live and function without a limited slip, on clutch styles I always restack the clutches for a tighter locker like function the way they are supposed to be. I do not mind the ratcheting on dry pavement cornering.By the way you have a power lock limited slip which is the strongest one there is, you can tell by the V shaped cross shaft.This carrier puts more force on the clutches with the more differential force put on it.The most common limited slip is the trac-loc which has full round cross shaft, nothing wrong with it either.

eventually im gonna do a detroit...
