I recently replaced the driver side wheel bearing and cv axle about 10 days later when you are driving when you get up to speed and keep it at a steady speed there is a very bad vibration. The vibration stops when you let off the accelerator, but when you give it a little gas it starts up again, I am wondering what this could be.

Try this:

Raise car, put on stands. Grasp tire and push/pull both horizontally and vertically, if any movement then possible wheel bearing, ball joint, tie rod, control arm bushing.

Check CV boots for any signs of leakage or cuts/rips in rubber boot.

Also check that you got correct axle, if remanufactured, and it is fully seated in trans.
