Range Rover P38 transfer box

Have a whining and slight knocking seemingly from the front driveline
on my P38, suspected the diff, but I've found there's some up/down play
in the front output flange of the transfer box. Everything else seems
fine. I'm guessing the bearing's failing, but so far the oil seal is
still holding. The manual shows how to change the oil seal, but not
the bearing. Does anyone know if this can be done with the transfer
box in place? Looks like the viscous coupling housing can be removed
with the bearing fairly easily, a ring of 6 bolts after the flange is
removed?

Alan:

Yes that will work.

Remember to replace both the bearing and race. The bearing will have to be
pressed off and a new one fitted. Race will need to be extracted and
carefully hammered back into position (typically using the old bearing).

Good luck, Jack

Excellent! Thanks Jack. Didn't want to remove the transfer box, it's
a bit heavy when lying on your back under the car. Does the chassis
cross-member have to come out though? Looks like it's a bit tight to
get the housing past it?
