I have an 05' Grand Cherokee Limited w/ the HEMI. After initial start-up when the wheel is turned, there is a grabbing sensation in the front wheels, like the wheels dont want to rotate. It seems worse the greater the wheels are turned. When the wheels are straight, everything is fine. After about 5min of driving, it goes away regardless of speed or angle of the steering wheel. Also, it just turned 70k miles. What should I be looking for?
