what psi?

 

Bent rear axle housing?

 

If the rear axle, you might try measuring the front and back tire width (measure from tire to tire across the front and back of the tires) and see if there is any toe in (or out), possibly due to a bent axle housing. You should measure no difference between the same part of the tire front to back. Or you could run a string along both sides of the truck, having it just touch the sides of the rear tire and see where the strings line up (should be parallel). Also, might be a camber issue (again due to a bent housing). Use an angle finder or square to check that the rear wheels sit perfectly vertical.

 

both rear tires are between 35-40 psi

max on them is 50

i've already ruled that one out.

 

axel bearings are toast.

there is a ton of slop in them
