I have a 2006 A&J conversion Thunder it is my dads truck but he put it in my name so it's mine when ever there is a problem. It has 20,000 miles on it. At 4,500 miles the pitman arm broke thank god he was not going fast and ended up in the on coming lane and no cars were coming. At 8,700 the arm loosed up again and one of the American Racing Rims were found to be defected. Part of the thunder package was 20 inch American racing Rims that were a 35inch tire. Rancho suspension and dual rancho stableizer bars. At 45-70 mph the truck shacks and has sense new, it steers like a school bus not sure if this is normal. I know it isn't but if you have any ideas I will be glad to talk to the dealership and ask them to check that. I don't really know and I am kinda frustrated. I ordered the raptor but in the back of my mind I hope it handles better than this.
