I have used search, went through 6 pages and tons of threads but I cannot find what I am looking for. What is the most economical way to address cracked and worn Rear control arm bushings? My uppers are cracked big time and I think this is the source of much of my "wandering" on road. Looked at Rockauto, and nothing there. Lexus OEM is over $200 each. What are you guys doing to bring these beasts back into some sort of decent on road manners? Pressing in new bushings? Or, is there a bolt on replacement assembly available? Thank you in advance!
