I've got a 2008 4wd 5.7 and my rack and pinion bushings are worn out and need replacing. Sunrise toyota is the dealer I bought the truck from and the guys there are less than helpful in trying to fix anything. They're telling me that the bushings can't be replaced and I need to buy a whole new rack. I have found aftermarket polyurethane bushings but only for the first gen. Anyone had to replace theirs and if so where did you get the bushings from?
