    Okay so i replaced the range selector fork in my np208 and sure it stopped hoping out of gear...now it makes a grinding noise after i get going a little bit...its like an off and on grinding noise....definately from the t-case....any idea's? I think the problem is that the shifter is not holding the t-case in gear enough...could be wrong...anyone had similar problems?

    The range selector fork has nylon bushings that fit on the "dog ears". When the old fork wore out it prbobly cut into the collar it rides in. What your hearing is hopefully not the new bushing and "ears" being ground to nothing again. Did you replace all of your thrust bearings correctly? I'm more curious if you pulled your output shaft and dropped all million and ten needle bearings like I did?!

    When i put my case back together I greased that shaft and then stuck it in the freezer. It helped keep the bearings in place a little longer. I dont think that grinding you hear is the tcase not engaging. The only time you should hear a grinding noise is going into low or out of nuetral when the planetary gear is moving. Your high gears should mesh pretty well. Try to put the tcase in 4 high and see if it still grinds. Hope it works out without another tear apart.

    Could be a thrust bearing, I dunno. It's been a really long time since I tore mine apart so I really don't remember all the little things I fixed. But it kind of rules out the dog ears grinding. As far as I know the chain is basically stationary when in 2 hi so that can be ruled out. I'd call some tranny shops and pick their brains a little bit. Good Luck. Lemme know how it works out.
