I have a bit of a concern over the rear mainshaft bearing orientation, on the 4wd box I stripped the open side of the bearing was facing the gearbox, on the 2wd box, the bearing had the closed side was facing the gearbox.

From what I can see, if I fit the closed side towards the gearbox, the bearing will run dry, as there is little to no oil feed to the rearmost housing where the speedo drive is.

the front bearing fits closed side to gearbox, but, the housing has slots for oil feed.

can anyone tell me the correct orientation of the rear bearing?

cheers.

Pete.

Dont remember clearly original setup, but bearing cover metal? it still have gap, bearing will get oil

Cheers, this is the bearing, the other side is open, just the plastic ball spacer ring.

Sorted, just re examined the bearing with a light, the plastic side is sealed, the metal side has a clearance where oil gets in, so must be metal side towards gearbox.
