It could be your rear diff needs re-built.You might be getting more power to one of the rear wheels witch will make it vere off in that direction or maybe your wheel nuts are to tight in the rear and making it do the same thing.

Check the bearings in the differential, and the condition of the CV shafts

I've had a similiar problem. Before you jump into the diff. Check to make sure your rear shock tower is complete and sturdy. I had a hair line crack in mine and casued my Ruslter 2.5 to do the same thing. Also think about some sturdier shock oil for the rear, make sure the shocks are topped off as well. If that fails you jump into the diff.
