A few time while backing out of my driveway the power steering has no power ( happened today twice) if I stop for a sec it comes back and no further problems, today there was a squeling involved, sounded like the belt and when I got home smelled like the belt but it worked fine. So my question is how long does the belt last, most I ve ever seen get more then 80-100k before they have issues but as with anythinng on this truck seems like it might be going. I havent checked in the belt yet because its pouring out, (Ive had it happen on dry days as well) any thought, is this a common issue that I dont need to worry about??
