Hello here,

I have a small leak at my transfer box (2007 4.2 SC , 90k miles)

There is a small amount of oil drips at the underside of the transferbox (gold oil)

I think it is coming from the seal at the output shaft going to the front diff.

Some questions:
Where can i find the partnr of this seal?
Is it difficult to replace? (remove shaft, anything else?)
Where can i fill oil and how much? Is there any oil level indication? Which type of oil?

Thanks alot

I found the topic about rrphil, opening the transfer case.

I think i need to open it to remove the output shaft...

Have a good trace first, before opening the box. I had mine re sealed twice, before I found that it was leaking from the o ring on the high low shift sensor on top of the box. Much easier and cheaper to fix. Was really difficult to trace as it wasn't leaking much. Give it a good clean then see where it's coming from  There is nothing that can't be fixed with a hammer😜😜

Ok thanks!

Will clean it tomorrow and check it

I had this problem and it turned out to be a crack in the casing! I had the crack weled by a specialist but it didn't cure it as he didn't put it back together properly, in the end
I bought the casings from rrphill and transfered all the bits over to the sound casings. It meant having the box out twice but its fine now!
I have a spare re-built box now if you are interested.

The underside of my disco one is a bit moist, but it's not getting fixed until it starts dripping, has been bone dry up until recently! There is nothing that can't be fixed with a hammer😜😜
