For the t-case gurus

[Jazona]

Have a t shift t-case and both the flanges at the rear of the case are leaking bad. Can I safely remove these to put new gaskets and a new seal at the output shaft without bearings, shims, gears, ect. falling out onto the ground or down into the case necessitating a complete r&r?
Thanks for any help.

Sorry, I didn't see the post below. That answers my question for the lower cover, how about the upper and the output shaft?

If you pull the output assembly out (rear driveshaft), all the needle bearings will fall out which go on the inside side of the output shaft. The input shaft (spud shaft) holds these needles in. It isn't too big of a deal as long as you pull the lower cover and fish them all out. I think there are 9 of them, but I could be wrong. It was quite a surprise when I pulled the first one apart and all those little buggers fell. Thought I was screwed.

On the front output shaft, just remove the front driveline, remove the yoke nut and yoke, remove the cover and replace the gasket. not hard at all and nothing will fall out on you on that one.

you should be able to pull just rear yoke and get to the rear seal with no problems

The good thing about the D20 is that nothing is spring loaded (except the detent balls) you can pull it apart without stuff flying away. As long as the parts go back in the same place, all is good.

Thanks, exactly what I needed to know. I've had way too many bearings fall down into a case and not be able to put the darn thing back together. Good idea on the other thread about putting sealant on the bolt threads, I might try that first.

If you decide to do the rear drive assembly you can stick the roller bearings back in place with thick wheel bearing grease before you replace the shaft. Then you can re-seal the bottom cover with a little RTV, for me it worked better than the stock gasket for some reason. Just my $0.02 worth.
