I just rebuilt my t-case and the splined rubber seal didnt really work... i then tried using rtv to seal it but its still leaking, i hate having marks all over my driveway!! What else could i do to make this stop???

Get another spline seal?  Also, it's not really called a pinion, it's just an output shaft.

I guess your right... pinions are on axles... brain fart...

I could do that but the first one didnt work, after being installed correctly. I was just wondering if someone has done/used something else to seal the output shaft.

What about those metal shims(they have a name, but I can't think of it) that are used to create a good surface when it has been worn down by the old seal.

He's talking about the spline seal, not the sealing surface on the yoke.
