Differential casting seeping

1288 Views 6 Replies 5 Participants Last post by  big gear head
The differential on my 66 Chevelle is seeping oil at the plug welds where the axle tubes fit into the differential casting. How can I fix that permanently? This is the original rear end for this car. It is a Kansas City car.

There's got to be some kind of two part epoxy repair that can be done there.
I’ve had succes by cleaning it up really well with a wire wheel and then using JB Weld to cover the plug weld to seal them up, then painting over it.

Have to drain the rear axle first though to keep it from weeping while you are doing the cleanup, unless it is out and you can rotate it around some.
