Well as winter comes around and soon to be snow on the ground and daily 4x4 use comes in to play... I begin to remember how hard it can be to get into 4x4 when its -30F outside. Anyway i can make engaging easier??(aka lever is hard to pull back and i have to work at it sometimes...)

 

Check the fluid level, and be sure the linkages are all adjusted correctly. 'bout all you can do.
