I had the shop replace every bearing and bushing during the install , the shop re opened it and adjusted the backlash. The whine is now very very vague. Almost non existent, I should of posted that earlier.

On occasion you can here a very minute whine. They said the Case and available shims just couldn't be perfect but that all measurements are well within spec. I trust them. Its about 5 percent of what it was originally, so far no problems.

Never experienced axle hop. The car spins fine, no wheel hop either.
