the input shaft bearing has been making some noise for the last mmm... 9 months or so, and this weekend i finally have the chance to replace it! i have the transfer case / transmission / bell housing combo removed from the truck, the snap rings removed, but still cant get the bearing out.
NOTE: both snap rings. one small, the other like a piston ring around the bearing.
i had the parts ordered, but started looking at them, and O'Riley ordered the wrong parts! i found the correct ones elsewhere.
back to the question, is there a special tool or a certin way i should hit something with a hammer?
tried sticking my tongue out while prying, but that didnt help much.

maybe its your pressure plate in your clutch or throw bariing replace all at same time
Can you pry the bearing (preferably on two sides) and at the same time have somebody tap the shaft in (say using a brass punch that won't damage the shaft)? I sometimes find this works when prying alone isn't enough. Also, is there any way to get a bearing puller on it? If so you might be able to rent/borrow one from a shop.
As a last resort heat works wonders (but for a tranny shaft it would be a last resort).
Whoa, easy hoss, don't beat pry or otherwise as you may do more damage than good. The front bearing has a split ring on the shaft and a split ring on the circumference. I removed mine by splitting the case at the adapter plate. I think the bearing can be removed through the front cover with a gear puller. If not, the case might have to be split. I am going to try to send pics of what it looks like, but it may take a while.

the bearing had been trashed. the spacer metal for each of the 7 balls of the bearing was gone. we had already removed both of the rings which held the bearing in place, and decided to grind just a little between the inside and outside to pop the balls out, then work on each seperately...
i stoped and looked at it just after starting, so i took two 7/16 head grade 8 bolts *around 4 inches long* and pushed the heads into the bearing.
the bolts were being held inside where the balls are and spaced equal. we used a metal plate with holes to push the bolts through and put nuts on them. there was a large hole in the center for the input shaft.
we were around 4 inches from the end of the shaft, so we used a large gear puller *2 prong* to grab onto the metal plate the bolts were attached to, and used the input shaft to slowly pull out the bearing.
after heating the inside race *not anywhere near the flash point of the transmission oil* the bearing poped, and we continued to turn the bolt on the puller and pulled it out.
i will snap a few photos and post them for a month or so to show everyone how i did it.

i was in fear of hurting the aluminum case, or even worse, bending the input shaft!
only a tefflon hammer was used, and it worked well. as for spliting the case... i've heard some horror stories about special tools being needed to put everything back into its place, so spliting the case was going to be the last option.
one thing i DID like about this all, is the new bearing has 8 balls! which means less space, and wont wear out as quick. *i hope*
thanks for the responces! i didnt think anything would come in too quick on the forum, with it being a holiday weekend. just had to scratch my head enough and stop thinking about the lake.
Hey, i got the pics up. They are located at www.geocities/aaronford1/nissan1 for right now. I am going to do some rearranging later, but this should work for now. The pics show the input shaft, front and back and the output shaft in which it interfaces. Just showing what is in there. Later I hope to have all my pics up. I did not take the pics to post, but for reassembly purposes, so they don't work as well as I would like.
Oops, almost forgot... Good job on pulling the bearing. It sounds like your handmade puller worked well. My bearing was a little harder to get to. It was the front bearing on the output shaft. The one the Creator had in his hand when he decided to build a truck around it. The bearing did not fail, it was the stamped steel/rivetted retainer that went TU and allowed the bearings to travel around the shaft and made one h**l of a racket.
