I have an 05 4x4 crew cab. Recently i started having no power steering at idle. It was'nt to bad at first, but yesterday I had to take it to the dealer. I am running 285's, and they thought that might be the problem. Anyone ever had this problem? The dealership is super nice and agreed to replace the pump and possibly the steering box also. Even though they mentioned the 285's, they said they will replace the pump as many times as they have to, to fix the problem. Just wondering if anyone else has had the related problems. Thanks.
