I am just finishing off my 2g tranny rebuild. I was putting my viscous coupler in and it won't seat all the way and I wanted to make sure I did everything right before I just tried to pound it in.

It is seating all the way until the shaft becomes flush with the top of the VC. So the groove for the snap ring is just below the surface. Does it just need to be worked in there? Or is this the result of something not aligned? If anyone has experienced this or has any suggestions please let me know. I'll be plugging away at it after I post this.

Ok, well I got it part way down by hitting it with a rubber mallet. But I still ony have half of the ring groove showing. This seems harder than it should be...
 
If you spun the trans while the VC was out the splines may not be aligned. There are TWO sets of splines that need to engage the VC.

You did reinstall the retaining ball that fits under the VC and retains the output shaft didn't you??

I have taken my VC off like 4 times now and had it back on. Now all of the sudden it wont seat on the last few centimeters. I know the ball is seated in the hole because the output shaft wont come out but I cannot figure out why it will not go down the last bit. Anyone ahve any ideas?

*Edit*

Figured it out. The ball that holds the output shaft in place had fallen out and was preventing it from seating. Unfortunately, this bearing is quite tough and while pressing it on I put a round deformity in the grooves of the front differential and now it wont slide on very well.

Pay attention to this ball. >.<

BFH. When I assembled mine with the welded center diff it was a mother ####er to get the VC back on with the light/moderate taps I was using at first so I manned up and gave it a few hard wacks and it plopped right on. They can be a basterd sometimes or just slide right on.

I gave up trying to get the VC back on the welded center. I ripped a VC apart and turned down the top section so it still retains the tranfercase shaft. No more having to deal with getting those stupid splines to line up.

I used this exact hammer and the rubber end came off. That's when I switched to a 'light' 3lb hammer. I had no brass :(
