[Fot] Leaky Pinion seal

[Bill Babcock]

Get a UV leak detector kit to spot exactly where it’s coming from.

I marked everything and re-assembled as it was to maintain the same pre-load; the diff was removed from the car so this was not difficult to do, and there was no wobble - i.e., the preload setting was good.  I'll check to see if it was migrating from the nut - interesting possibility, though I'm pretty sure from the visuals that it is at the seal.

Also possible is I have seen leaks from the behind the pinnion nut...oil migrates up the shaft past the splines and out from behind the nut and washer...assembling with a little silicone helps this. Did you get the flange back on in the same attitude as it was before dis-assembly....in other words did you mark the flange and shaft and tighten the nut to the same spot....this is what sets the pinnion pre-load and depth
