Leaky transfer case

[351bolt]

97 Explorer 4.0 SOHC, control trac. Transfer case is leaking and has been for awhile. Does not leak alot, but over time it leaves a mess. It looks like the back half of the case needs to be pulled off. How hard is that to do? Can it be done with the transfer case still under the car?

Thanks

Mine once leaked from one of the speed sensors on the back of the transfer case. If this is where yours is leaking from, it is simple to fix - you just need to replace the o-ring around the sensor. You may need to remove the shift motor for access, this is also not difficult.

It looks like the case is two parts and it is leaking from the seam.

Bummer. I think you need to pull it out if you need to split the halves. I haven't done it, but there is a thread somewhere here with pictures. Maybe Izwack?

IIRC, it does not use a gasket - you use RTV gasket to join the halves.

Yeah you can use RTV to join the two halves together.

But first make sure it is actually leaking where the two halves come together -- because it could leak from somewhere else and drip down to where the halves join (which is the lowest part).
