Leak...?

New topic...what needs replaced?


I mean, I know it is coming from the diff. I looked about and there is not wet spots or any signs of dripping. Just curious what I can get greasy doing this weekend.

The rear pinion seal looks to be leaking. Breather tube looks like it has a leak as well. You'll need to know what rear-end you have for the correct seal and don't let the caps fall off the U-joint.

Yes you have a Dana 30 front axle with a pinion seal leak and a small breather tube leak.

The pinion seal is rather easy to replace and can be done in an hour or so depending on bolt conditions. There are a couple of writeups online that explain how to do it. The breather tube leak is probably a small crack or split in the hose. A new hose and clamp would be an easy fix. You could probably even cut off the end a little bit if its cracked and reconnect it.

Check your fluid level before driving more to make sure you still have adequate oil level to cool and lubricate properly. The level should be up to the bottom of the fill bolt.

The sad thing, I even looked right at the exhaust and oil pan and still called it the rear seal. Thank you Jeepwayoflife!
