Noticed that the real axle seal had leaked on the brakes, so popped the cover on the rear. The oil in the rear has turned to Goo. Almost like tar. Is there something I can add to the rear end and drive for a few miles then drain that would help liquify everything?

Dig out what you can first and add some replacement gear oil to make up for what you dug out. It shouldn't take long to soften up.

Left the halogen light shining on it for a few hours to warm it up. Ran the truck on the stands for about ten minutes. After draining I pulled the inspection plate off of the back, and brushed/ rinsed with kero. Put 'er back together, filled with oil, changed after a hundred miles.
Basically, what Joe said, but I've had a whole lotta coff-ay. | | | | | Joined: Apr 2005 Posts: 1,971 'Bolter | | 'Bolter Joined: Apr 2005 Posts: 1,971 | I guess I would check the bearings and races for replacement while I was at it. | | |
