mine did something similar when i stripped out one of the rear hubs. i stripped out the right one and the left one pushed me to the right. when i jammed on the brakes only the left was grabbing so it would pull left when stopping. something very simple to check on.

 

inspect the brakes first. then the tierods. then the ball joints.

if the brakes are dragging, try bleeding them real good all around.

bearings?

 

its your hub

 

Its your 4 wheel drive hubs not disengaging or not fully engaging in the front (depending if you are in 4 wheel drive or not). They are disengaged enough to not turn the wheel, but engaged enough to cause it to drag.....

It happens regularly to me if I dont change the hub fluid often.

Change your front hub fluid, and change it often. I run mobil 1 synthetic ATF in mine, and change it about every other ride. It gets dirty really quick since there is so little of it - but keeping it clean keeps the hubs functioning properly. Synthetic helps that much more - and its more tolerant of heat.

The hub fluid is CAKE to change.
