Well, anyway, the truck is quiet now.......
I also tried to get the dealer to replace my passenger side torsion bar because the adjustment bolt was cranked up about 7/8 from the factory (drivers side only about 1/3).....doesn't leave me any room to adjust front end up an inch or two. They gave me the polite "dealerese" NO. Oh well, I'll try again next time...or maybe another dealer.
