Does anyone know if these trucks came with limited slip rear diffs, and if there is a common problem that keeps the, from working? After recently getting stuck in the snow it now feels like ONLY the rear right is trying to drive. Any help would be great. Thanks!

I dont think so, I belive they were a option on the 7 lug's and the 99 off roads, and the 00+ fx4's

I supose you could decode your door jam sticker and see if you had it.

also, if just one wheel is turning, you have a open diff, or one bald tire.

Look at the tag on the rear diff. It will say 3 L55 or 3 L73 if its limited slip.

Check the axle code on the sticker inside the door frame on the driver's side.
Write it down and look here:
