Tranny needle bearing

[willysrul]

I have a 93 nissan 2wd went the prerunner route with it and now my second tranny has grenaded a needle bearing somewhere in it. I pulled the shift lever and top cover and proceeded to pull out remnants of what used to be a needle bearing pack + one needle bearing (very small). Has anyone worked on these trannies 5 speed FS50W70C (I believe is the number) or would it be easier to pull a used one from a different year that will bolt up to mine. Or should I bitch at Nissan since this one only has 47K and my first one that totally lost everything except 4th only had 34K on it!????? Any help with this tranny would help. Fix this one or find a used one from a different year/make?
Thanks,
transfercaseless no go!

Never worked on one of these trannies, but I have one. There was a defect in the case that nissan has addressed at one point. The fluid fill hole is too low on the case, so if you only fill to the fill hole you are 1.25 quarts too low. This low fluid condition starves the bearings for oil and they die quickly. I think this appplies to the 2wd trans as well. To ensure that the next trans lives longer, add an extra quart through the shifter hole, or park sideways on a hill and pour it in through the fill hole.

I think you can find a rebuild kit at www.4x4parts.com.

edit: I just looked and couldn't find it. sorry.

You can fix the oil problem with a couple of parts from the plumbing section at the hardware store. Just add a 90 to the filler hole and it will get the hole up high enough.
