I currently have my SWB rear axle removed and have welded on a new diff pan replacing the one which had rusted through. I removed the diff to do this, and replaced the pinion seal that the same time. I am now re-painting the axle before fitting new springs and refitting to the vehicle. I left the axle diff pan down with oil in it to check the integrity of my weld, and it made me happy by not leaking. I then turned it pinion side down to paint it and it is leaking from that side.
On a closer inspection the neither the new pinion seal or the new diff-casing gasket are leaking. The leak appears to be coming from the studs holding the diff to the axle and working its way down past the nut. Has anyone else come across this problem and has a miracle cure?
I am fairly sure it did not leak from there before dismantling but it is difficult to say as I was running a total loss system due to the holes in the diff pan and everything was covered in oil.
