Well fellas I finally worked on those hubs and they seemed fine. The bolts all came out like butter. To be certain they were not the cause I swapped the hubs from one side to the other side after I was sure they were fine and the truck still pulled to the left in an extreme manner. I need some new front end parts but I see no cause for it to pull that bad and when the 4x4 is engaged it stops pulling. errrrr.

The Toe checked out great so unless I have a camber issue I am at a loss why it would pull that bad. The front axels are not turning when in 4x2 and like I said I swapped the hubs from one side to the other and the pull is the same. The only thing I did before all this happened was add grease to all the front end parts because most had no grease in them.

Any more ideas what could cause it to pull so extreme when in 4x2 but not 4x4?

I even took the tire off the side that was pulling and put the spare on. Same result. When I say it pulls I mean it will go around corners on its own. It will put you in the ditch inside of 100 feet if you let go of the wheel. The steering wheel has to be held way past center to maintain straight line. Could the alignment be that bad?

A side note. If I am turning into the garage or unleveled ground the front end makes load creeking noises like something is moving. Cab mounts look ok and when following the truck it looks to track down the road correctly. No dog walking.

Ideas?
