My transfer case on my 99 gmc jimmy is leaking. It is leaking out of the rear seal where the slip yoke enter the transfer case. It started after I replaced the transfer case fluid. I used the blue fluid chevy says to use. I also replaced the seal that the slip yoke goes into. Ive tried everything. My next thought is to get a remanufactured drive shaft cause a new slip yoke can only be bought from chevy and cost about the same price as a whole d shaft?My father is a gm service director and told me the slip yokes are known to get groves in them and cause a leak. Another thing I was thinking could I be overfilling it. I fill it to the top of the fill plug. I had some say maybe you are over filling it and it is coming out the seal cause it is over filled. I have no idea anymore. Any help would be great. Thanks
