Good call Bill! I called Jim and he has what I need for less than the unit I found on CL. Actually costs less than just the bearing kit if I were going to rebuild.

I've got Bud's single case cross member and skid, Isaac I think has single case cross member and skid and Dean has a double case cross member and skid on his 1980.

New development. The weather wasn't bad last week so I took the hilux for a drive. I had the hubs locked all winter, but I unlocked them and drove it around the 'hood in 2Hi. No noises... I put it into 4Hi with the hubs unlocked. No noises... 4Lo with hubs unlocked. No noises... Would this indicate that the TC is not the culprit and that it could be something in the dif, axles, birfs maybe? Can anyone think of any other tests I can do to figure out where the problem is before I spend $ on parts.

Yeah, it could be a lot of things. Not to mention that don't for a second think that even being a mini truck and not a Cruiser that it will be like driving a Cadillac. Even my relatively modern junk still has gear whine and stuff. My Marlin transfer has a very distinct whine from the front drive gears, even in 4 high (it's actually much more pronounced in 4-high because of the speed).
Anyway, have you done a fluidectomy? I would get fresh gear lube in all the places before anything else. I know you said you drained the t-case and that it was in good shape, but also the diffs and tranny, right?
The sound was a thud-thud, which to me is not a normal driveline sound, but also not necessarily meaning major failure (yet). My original diff gears were worn enough that I would get a thunk starting from a stop, the splines in my rear prop shaft are currently giving me a thunk from stop. I also get a metallic ting once in a while when my exhaust kisses my well bent up skid plate. Worn u-joints make weird noises, too. On an old mini truck I would suspect u-joints of being marginal.
I would also consider the possibility that you have badly worn or broken motor isolators. Particularly the cross member one, when that gets bad things tap each other, shifter arms touch sheet metal, cases touch cross members, etc.
So yeah, I think it's possible that it's not an immediate t-case issues. Good fluid, no shavings are good signs. There are no synchronizers in there to fail like a tranny, so it's pretty simple to tell if a bearing has failed, the pieces will be silver and there should only be a little shine to the oil on the drain plug magnet from the gear faces. Sometimes when trannys fail the yellow metal parts not being magnetic won't be obvious on the plug and you have to watch the lube for them.

Thud-thud almost sounds like a ring gear.

Anyone want to go for a test drive and listen to this thing?
