thats sounds like it could be true to the problems im having, all the noise (grinding) is always in the left front wheel. i know when i had the hub off, i could see the gear force out in 4wd. but when i would put it back into 2wd it was real sluggish to retract the gear. What do i gotta look for as far as what ingages, and disingages the gear for that left side? hopefully you guys can save me alot of poking and hoping,and lead me in the right direction, as far as where to look.
