yes on drive shaft removal
if you can move the tire in/out 2'' before the other tire moves that is'nt normal.have someone move tire in/out while you look at steering linkage. should be fairly easy to see with that much movement.

Good luck

you must check the differential codes to see what you have ..with what your saying the differential is not a locking or limited slip type but an open diff...just one wheel provides traction. both rear wheels off the ground moving one wheel the other may move ....

with a locking diff or limited slip spinning the wheel off the ground will lock up after a few rotations locking type, the limited slip type you would need 50 ft lbs of torque to get the wheel to rotate...


on the drive shaft remove the rear drive shaft U joint support brackets ..mark drive shaft to put back as removed..tape the end caps so you don't mess up the needle bearings.

you never use the capacity to fill these boxes...you fill to about 1/2 inch below the fill hole...drive vehicle a little bit then recheck.

make sure on a level surface. these gear oils expand when heated so overfilling can cause some to leak out.
