got a 2000 sierra 1500 with a steering issue . its hard to turn to the left even when moving but only to the left and it only does it if its been sitting for more the two hours. Its only about a half turn of the steering wheel then it releases. any help would be great

 

So almost like the steering feels like it's catching on something? Does your power steering make noise when this is happening?

 

Put a half a quart of marvels mystery oil in with the power steering fluid. One of my trucks did that, and i used that method to fix it.
