Pinion seal leaking, help with change (1 Viewer)

[spike6901]

Can I get to the pinion seal on the rear differential from the drive shaft side or do I have to pull out the entire gear set?

you can get to it from the driveshaft side but....

You are going to need air tools or get real creative. Also, didn't 79+ use crush sleeves for pinion backlash? I would assume you can reuse it but it isn't a good idea?

Check carefully for surface wear on the diff flange surface where it contacts the seal. I found a new seal did nothing for my leak, and it was the speedie sleeve that cured it.

Of course if your paying $33.99 for a speedi-sleeve, get a new flange

Napa is one of the better Speedi-sleeve sources here in town, usually ~$20-25

Spike,

Take it from me, if the pinion seal is leaking, it could be because your pinion is flopping around.

Or you have a groove on your pinion.

But nce you pull the pinion, go in there and look at the shims, make sure they have not cracked or spun...
