2005 CC Nismo 4x2 is finally leaking from the right axle seal, and at 90k miles is waaay out of warranty. Pinion seal and left side are still good, so I guess we found the path of least resistance on the right side.

I've found all the posts/stickies about the problem, but I cannot find the part number(s) for the seals. Has anyone posted them?? Sorry if it's a stupid question -- I did try Searching the forum first.

What I'm finding says there is the axle seal, an o-ring behind the brake backing plate, and to replace the four nuts that hold the axle in, so I suppose I need the part #s for those three things. Anything else?? Any advice?? Pitfalls to avoid?? Planning to do the axle vent mod at the same time to prevent any recurrence. Found something saying that a Titan rear diff cover will fit and there's a nice gasket to use instead of RTV. Any truth to this?? Which years/diffs will work?? Part numbers??

Thanks in advance,
Chris

I'm wondering all the same questions as I just discovered my axle seal is leaking as well. I know there's 2 different seals and I think the inner seal involves some cutting of things. I am pretty sure that any titan rear diff cover will work on our M226 diffs and the gasket is made by Mag-Hytec who also makes finned covers.
