RE: Steering very hard when cold
its hard to say exactly but i had to put a pump on my truck at 120k cause the pump shaft broke. ive heard from a few people that the pumps on these trucks were a problem. i put a used one on and have put another thirty thousand on it and its starting to havemoments when it steers hard again. But i would definately check all the ball joints to because they could cause this problem to if they start seizing up.
