If you use grease it will migrate into the transfer case and mix with the ATF and could lead to serious problems by contaminating the fluid in the transfer case. Service bulletin out on this, grease is only to be used on 2wd trucks.
Thanks... I saw the bulletin , I already tried the Dexron ATF fluid but it had no effect at all..
