do you just fill them up with 140 weight until gear oil runs out of the fill hole like with a diff?

 

Does yours have the drain plug?

 

not sure..i'll have to scrap off some mud..the PO kept this thing really nasty..so some have a drain plug?

 

wait a minute..I was thinking 140 weight for the transfer case...the swivel pin housings you just pump full of grease right? thats what was in there..grease

 

yea they switched to gease to stop leaks

 

Yes, use 85w-140 for the diff and t-case and the same grease that you use on the u-joints in the swivel *****.
I do 20 pumps with my grease gun per side every 6 months.

 

doesn't the manual call for 85w-90 for the diffs?

 

Sure it does, it also calls for the Land Rover dealer to do all of your work.

 

i think 140 weight in the rear might be too high a viscosity to lube the wheel bearings properly..has anybody had problems running 90 weight?

 

I have been running 85w-140 for 2 years now with no problem, even in the winter time.
The only thing I notice is when its really cold and it has sat overnight the truck will not idle itself out of its parking spot, I will have to give it gas to move, but this is in near zero temps.
The thicker lube will quite things up and reduce drive line slack.
I can almost guarantee you thats what they used because of all the hard wheeling.
If it makes you feel any better DiscoMike uses 75w-140 in a full syn, I use it in dino.
