I have three Dodges. I have a 1996 Ram 3500, 1999 Durango 4x4 and a 2000 Durango 4x4. Both of the Durangos have the standard chrysler 9.25 rearend and my Ram has the dually dana 80. My ram and the 99 Durango both appear to be seeping did fluid were the axle tube is pressed into the differential housing. No other seals appear to be leaking. What's the fix here? While not an easy task, I'm not against welding the joint, but if that was normal, it seems they would already be welded.
Anything you can offer would be great!

 

They are pressed in, and then plug welded to keep them from coming out. Ever.....

Living in arizona, I doubt that rust is the issue... but, that's what I would expect around here.... (michigan) Does it look like the tube is pulling out of the housing at all? (that would be a real shocker) Welding a bead around it, or maybe even JB weld would be adequate to the task.

 

I don't see any signs of rust or any obvious signs that they are coming out. Just seeping. We have some rough dirt roads and trails around here so it may literally just be all the shaking about letting a little gear oil out? I may try jb weld on the Durango and weld the Ram. Thanks!

 

This was common on Ford 8.8s

I doubt you're gonna have any luck trying to seal from the outside.

Welding the tubes is common in the offroad world to prevent spinning the tubes. But there's some caveats. I'd watch this, and I wouldn't do any less 'cause if a weld cracks it's just gonna leak again thru the crack

 

I'm going to check that out now. Thank you!
