Transfer Case

The other day when I was under my Jeep I noticed a small patch under my transfer case where the two halfs meet together. I assume the two come apart, is there a gasket in there that can be changed? If so is it something I can do at home.

Thanks

Its sealed with RTV.
Don't know how hard it is to take it apart or anything though.

Not hard to do,

NP231

- Drop Rear Drive shaft
- Drop Front Drive Shaft
- Remove Front yoke (think its 36mm)
- Remove Bolts from Transfer case housing
- Carefully seperate the two halves
- Clean mating edges with a solvent (brake and parts cleaner)
- Apply RTV
- reassemble Gears and chain on the half that is not in the jeep and slide in as an assembly
- Put it back together.
- Fill with 2 quarts of ATF +4

Depending on mileage of the Jeep you may want to look into a new chain. I believe the chain is only allowed 1/32 of stretch before it needs replaced. Last one I got was from Mountain valley customs out of PA I'm thinking it was about $170 not totally sure though. I just know that was the cheapest place I could find.

Fixed it.

It's much easier doing the split seal when the t-case is out of the vehicle and then place input side into a 5 gallon bucket,makes life much simpler.

Oh and use aircraft grade RTV,the red stuff that never get's hard,stay's a gel form.It's outrageously expensive but the best to use for a t-case split seal.

I can split, replace the chain, seal and be back on the trail in 1.5 hrs off the floor. Its really not that hard. By the time you pull the T-case I'll be pulling it outta the shop.

I believe what Troy suggested was appropriate for most shade trees with less experience in working on things while under the vehicle
