Thread: Transfer case (LT230) leak into gearbox R380

Not normally possible but someone might have siliconed together the two items instead of letting the oils drip out of the gap between the two adjacent seals.

As above , for that to be possible, not only would the two half's have to be siliconed up , but gearbox output and transfer input seals would both have to be u/s , oh and don't run epx 90 in the transfer case it will ( if it hasn't already) burn out the centre diff spider gears / shims

What should be run in the transfer case then?

It's hard for me to believe that the gearbox would "suck" oil in if it's a leak also it's higher pressure in it than in the transfer case... for LT230 75W90 oil is recommended

It may be coincidence, ( or people 4 wheel driving without cdl ) but the Lt 230 's I've seen with the spider shims burnt and the oil muddy like you describe were running 90 . I use 75/90 .
