just a word of warning, I had a similar vibration failure on my 300D a couple years ago, where the car started hopping and jumping, and the axle had heated up enough that it was nearly impossible to remove easily, the joints were really sluggish to move, and i could not compress it to get either side out of the diff or hub. I ultimately had to cut the dam thing in half to get it out.
It could be bad, just for contingency planning on your end
