Okay after finally getting the pattern and the whine out of my 410 setup. The rearend is leaking. The leak is betweeb the front seal and the pinion yoke,(that gray plastic piece that is part of the yoke. Do you guys have any ideas? I installed a new front seal and a never messed with yoke.
no its no the crush sleeve, if the crush sleeve wasnt colapsed then it would have a lot of free play and it would sound bad. If it was a crush sleeve you would definitly know it.
