Anyone seen a D30 pinion seal fail in 10 miles?



Wanted to make sure I didn't mess up the seal , so I had a buddy that's a tech and does work on the side at home do it. Wake up this morn and it looks like the seal is toast. Any ideas? My first thoughts are over tightened, breather clogged, or possibly something to do with a bad bearing? All I did was drive it home 10 miles or so... thanks

Wow! Never seen this before. I would say something must be on the yoke or inside near your outer pinion bearing. If you think about it that seal sits stationary in the housing. The only contact is very lightly the rubber seal sliding on the yoke. The seal hasn't failed that bad, something is contacting it. I would pull the yoke check it. If it is good I would look at the oil slinger and outer pinion bearing.

I bet you either ordered (or the counter guy gave you) the wrong seal. There were at least two pinion seals used on various year Dana 30's in jeeps and maybe another in broncos.
I don't recall the numbers, but I do recall replacing a "professionally installed" seal after about 3 weeks and noting that the new one did not look like the old one.

97 TJ Sport OPJ project (other peoples junk) I can't remember the last time I bought a new part.

This was a national . Replaced with a Timken today .same thing happened !

Some buddies suggested maybe breather is clogged and its boiling out. And another insist the carrier or pinion is not seated correct after the locker install. It not not start leaking until the locker a few weeks ago. But when I pulled cover almost No fluid came out. I just recently purchased the jeep.

Incorrect installation of locker. I suspect incorrect seal as well, if not, then it's runout in the pinion. Who did locker install? Correct sealing after gear work is the responsibility of whoever did the work on the differential.

The technical advice you get from me here is worth exactly what you paid me for it. Warranty issues will be reimbursed at double what you paid me for the advice.
