Lower Control Arms was badly rusted along with the attached retaining nut welds for the Stabilizer bar link attachment. Lower Control Arms Camber bushings was rusted out & frozen. Had to cut out the control arms to get it off. As a result I needed a full Alignment which Toyota Dealer didn't have capable Mechanics to get it right. I had to replace Ball joints, Stabilizer bar links & tie rod ends. My Tundra chassis continues to rust out on this Truck , Toyota should have replaced all these chassis but failed to do so & I think it's unsafe as the truck aged. I have never had a vehicle with chassis rust.
