Rear diff leakage


Recommended Posts

I thought it was the pinion seal, replaced that. Cleaned everything up and headed off. I hopped on the turnpike. Two hrs north to a lil vacation spot for my wife n I. The next morning I went to get some coffee and It was almost like a horror film. Fluid everywhere.

 

I put a piece of tubing and a hose clamp at the axle tube to help "hold the leakage" so I could get home. I filled the diff with nearly an entire quart. I kept my fingers crossed and the radio off until made it home.

 

Just a few questions to powers that know. Can a leak form at the axle tube? Should I have it welded? It doesn't appear to be tweaked at all. It also appears that a leak has sprung on the axle seal up by the brakes.

 

Should I be looking for a new rear? A few pics....

None that I'm aware of. It's odd, I've had the truck for a little over 4 years. It just got this bad within the last month or so. There was definitely a leak from the pinion gasket. I think I'm gonna bring it in to a shop to see if they can weld it. Or see somthing I can't. Thanks for the response guys.

There isn't a seal at that location, the axle tube is press fit into the center section and plug welded. Welding it completely may distort the tube causing further issues. The simplest solution may be to clean the joint up with a wire brush and some brake cleaner, then seal it with some black RTV......
