Where's the diff leaking from?
Hard to say exactly, the bottom :laugh:
It think it's leaking from shaved area.
I fought a leak on my D44 for years. I finally got a lublocker gasket and never a drop since then.
Mine's a bit different. Mind had a heavy shave done. Unfortunately, I didn't get the bottom plate 100% flush with the face of the housing (very close, but not perfect). So, I think the leak is due in part to that.
It did seal for the longest time, but has been an issue since late last year.
If I had access to one and a bit of free time, I'd throw the housing and the cover up on an end mill and mill both surfaces 100% flat and even.
A lubelocker might be nice for my D60, but that one doesn't really have any issue sealing.
I *think* I might have found my culprit on the tranny pan. I drilled and tapped an additional hole near the driver's side rear corner on the pan/housing to help seal. Well, the drill hole went into the actual fluid area (nothing near there), so it's another "hole" that can seep. I used thread sealant on the bolt when I screwed it in, but that may not have been enough. I pulled the plug to let the pan drain last night. Hopefully some RTV smeared on the bolt with a dab in the hole should take care of it. It if does, that saves me a day of work from removing the UHMW boat sides enough to get to the cross member bolt heads, swinging the cross member down, removing the pan, etc. etc.
