1998 B7300 Axle pivot leak...

[Muttandjeepss]

Got a NTM 98 B7300, great shape, except I noticed and oil leak after getting it home. The axle pivot is leaking pretty good on both side of axle.
Have a WSM manual on the way, any advice from those that know how difficult this job is?
Thanks in advace!

Easy repair, just a couple of O-rings and maybe bushings if it's warn too much.

I'll post pictures in a bit.

Thank you for your time!

You more than likely just need new O-rings.

Jack it up off the front of frame, and block it up, remove the bolts and drop the axle.

Perfect,thanks. Will order the o-rings tomorrow, and hopefully be able to get it done this weekend.

I had the same issue on my B2400 and 1st I tried replacing the pivot ends front and rear (with new O-rings) lasted a few months before leaking again. If you have more than a small amount of wear on the bearing surfaces on the axle housing itself it will leak again. Fast forward to last fall: I ordered the complete front axle kit which includes the axle housing, front and rear pivot castings and seals etc. (mine had Bi-speed steering so a bit different and more work). The new axle and bearings are redesigned and completely different (better) from what you have now. This requires complete tear down of the axle and differential, I recommend having a shop manual for guidance.

I have leaks(s) and have order new O-rings. Do I have to release the drrive shaft to replace the O-rings? A little more guidance would be greatly appreciated.

The drive shaft and cover will slide off when you pull the axle out.

Thanks for the quick reply. Does the drive shaft slip out of the coupling after the pin is removed, leaving the bevel gear in the case?

Nope no need to remove the pin, the pin on the coupling is between both shafts and just keeps it from sliding back.
