    Ok... A novice with a novice question.

    I have heard of using "knuckle puddy" for the steering knuckles to help minimize leaks.

    What adverse affects would a thicker "puddy" have in a transfer case? With the more extreme temperatures what kind of issues would arise with a oil/grease mixture?

    Am I correct in thinking this would help with the notorious D18 leaks?


    Am I talking out my .... [​IMG] ;)

    The puddin would not be good for the 18. it rotates at a much higer speed and you more parts to protect, i owuld just pull the Tcase and install new rear seals. There is a double lipped seal available for it, but i forgot the seal nubmer. i think Lynn had the number or somebody else did. Just make sure when you install the new seals that you lube the rubber surface of the seal so that it doesnt burn out, which is why alot of seals fail. The puddin is good for the knuckles but woulnd probably ruin your Tcase.

    I chased leaks on my D18 for years and finally got serious with it... 2 problem areas I had were the bolt holes for the bottom pan, I put ultra copper on the bolts, and the stack of shims on the rear output... I put a very thin film of ultra copper on each side of the shims before checking the backlash on the bearings it adjusts. No leaky in 5 years so far....
