My steering has started to bind after taking sharp turns. It will pull to the side after turning sometimes untill I jerk the steering wheel the other direction. I jacked up the front end and checked ball joints and the u-joints, I noticed that with the wheels turned all of the way to either side and the front hubs locked the right side u- joint locks up while spinning the front tire. If I unlock the hub the axle\u joint assy does not spin or bind. So my question is when I am driving with the hubs unlocked could the front axle shafts still spin enough to bind with a froze u- joint? or should I be looking elsewhere.
