HI , I'm new here and I just got a brand new with 12 miles on it, 04 Silverado 4wd that is a Southern Comfort conversion.I reallly like it and want to hop it up but first I need to know what to do about the hard steering.When I have it in gear and need to turn the steering wheel it gets real hard to turn if you are not moving .It feels like the power steering just quits.If you let it creep then its ok but sometimes you are in a tight spot while trying to park and that isn't practical.The dealer says he's heard of the problem and its caused by thebig tires and rims but there is nothing they can do.It was bought new with 18 rims that Southern Comfort installs before they send it back to the dealer.I just need some idea of where to go next. thanks
