The front left frame that the wheel and suspension bolt onto is in advanced rust stages. It is being considered unsafe to drive although the right side is still considered safe.

Vehicle shakes violently enough to jar your internal equipment even if you go over the smallest bump or expansion joint in the road . Returned to dealer 5 times for same complaint dealer said there is no fix. Even though we informed him that truck was uncontrollable on wet pavement and made you motion sick. Dealers service manager was convinced to ride in the truck and stated " this ride is unacceptable".
