I have a 2005 FX4 i have recently changed out the hub and the cv joint, once I had the truck in the air I turned on the 4low 4x4 and only three of the tires spin? Is that normal? I thought if I had it on 4low all the tires/wheels move? Can somebody please help?

 

You have limited slip diffs. 4low changes your gear reduction through the transfer case but does not affect your differentials. If you want all 4 to always turn you will need lockers.

 

That's great to hear. Thanks you have put my worries to rest.

 

yea ur good

 

Block the front wheel that's turning and the other front wheel should start spinning. The front diff is an open diff.

 

Yep... open dif. up front... sounds like it is working correctly.

 

Sorry I did give a tid bit of incorrect info, open dif up front limited slip in the rear. Thanks for the correction guys, dont know what I was thinking.
