Pumkin' fix'n


When I got the car last spring, about 200 miles ago diff was singing a bit. Was told by the ex owner that they had the pinion seal replaced time to look at things, 1st the vent wasn't working, and second the pinion was way I mean way to tight could not turn it by hand, so I loosened it needed the air wrench then tightened it up by hand with some preload, sang less but still time to fix. Parts on way from Summit doing wheel bearings as well. I'm guessing that the pinion nut was tightened with air wrench quite well the first time.   Laurie

Must have been a bit hot when running?

One thing you can do is add a drain plug while you have it apart, drill a hole in the right place and weld a nut in place inside for it to screw into.

It is together and installed, I drilled and installed 1/8 npt socket head plug no welding, wheel bearings getting pressed on tomorrow and we drive again. Haven't done a small diff like this for years last ones I did at work were out of Champion motor graders no by hand lifting there! Laurie

Changing the bearings didn't work still sang! Kept me awake all summer. Changed the wheel bearings one leaked in 150 miles, was a Kumo bearing from Japan replaced it with bower bearing made in China worked not to bad. Move along to end of October got another pumkin from Pontiac previous owner got axles also they have real good bearings and price was right just take it out. Put it in and now things are quiet. had to replace the China bearing leaking this time got one on warranty.
