Does your rear diff leak gear oil everywhere? Do you keep installing a new pinion seal and having the same problem? Everyone has or will have this problem when installing a new pinion seal in your 12-bolt GM rear differential, but Hagerty’s Davin Reckow is here to help. GM made two different versions of the 12-bolt rear end: one for trucks, and one for cars. This means two different pinion seals. Unfortunately, the car version of the seal has been discontinued, and the truck version is the only one still available. Even if you walk into your local parts store and tell them it’s for your Chevelle or Camaro or Impala, the one they’ll have is the truck version. Most shops don’t even know there was a difference. The solution to this problem is installing the available truck version of the pinion seal by using a spacer or by leaving a gap. This is the only way to ensure a quality seal with the yoke. Watch the video, solve your leaky rear differential problem, and maybe even be the hero and your next local cars & coffee.

I wonder if a Salsbury 10 bolt diff seal would work?
SELL THOSE RINGS
Most will just drive it with a small leaking
Is that a frog eye sprite bonnet in the back ground
But if the yoke is bottomed out in the seal spacing it from the diff housing wont make a difference no?
The seal on my 9 inch needs replaced.
That’s a great tip
Correct me if I'm wrong, but the yoke still on goes in so far, on the seal, because of the construction of the of the seal. You will have the correct spacing to the bearing however.

The pinion bearing is supposed to move 1/8-1/4 inch?
