Check your pinion nut, a quick look chock the wheels, and then put it in neutral to relieve any load on the shaft, grab it at the end yoke and see if you have ANY movement up and down or in and out, it should only have some turning movement but NOTHING in any other direction.
If it has any movement other than what it should , either the nut has loosened, or the bearings are in need of replacement.
