ok i was tryin to use my 4x4 the other day and i put it into 4 hi and you can hear it click but my front wheels wernt spinnin at all. whats the problem.

i researched it a lil bit and it said it could be the accuatior.
but i asked my buddy about it and he said my trasfer case might be shot. and to get a rebuild kit for it.

i also need to replace the u joints(front and rear) could that be a proble too??

really nee your help on this one guy.

 

Your transfer case is likely working perfectly fine.
