Hi. My 1998 LS400 has negative camber on both rear wheels, and light side to side shimmy when going slow.. The tires are extremely worn on the inside to the point of the steel belts are beggining to show, and I plan on getting new tires tomorrow as they have 50k miles on them anyways, so the left to right shimmy may just be from them. The vehicle has 320,000 miles on it and I've owned it for most of that, so I know nothing much has been really done to the rear wheels besides brakes, rotors, and such. The front, due to more wear, gets it's ball joints, control arms and bushings replaced regularly as needed. I know the rear camber is adjustable, but due to the high miles, I'm thinking it might just be out of specs more due to bushing rot or wear. Does anyone know which bushings on the rear might cause negative camber as they wear? Some people have said to replace the carrier arm bushings (ADUS 505 or PD 505 types). Does anyone know if these are the ones most likely to cause this? Any help would be greatly appreciated.
Thanks in advance
Randy

there are a lot of bushings back there to rot/crack/tear/etc.
you will need to get under there and assess. when you get new tires ask the tech to see if they can inspect the bushings as they mount the new tires.

that is a lot of miles and seeing that you're in the snow belt, it's likely there is major bushing damage.
yes the camber is adjustable but i am willing to bet it's bushing related.
you saying the car shimmies when driving confirms this!
