Some of you may have seen my thread on the 2004 Lexus RX330. It is a pro-bono job for my landlord. The car has worn lower control arm bushings. Since Toyota does not sell bushings separately, the options were either OE arms ($400) or aftermarket control arms ($70-$110). While she begrudgingly approved the OE arms due to durability concerns of the aftermarket arms, the cost of the OE arms is a bit asinine. After doing some additional research, it appears that Moog does make a "spherical design" control arm bushing for this application. The Moog bushing is a ball-and-socket bearing that is permanently lubricated (and sealed), and take the place of the OE-style rubber control arm bushing. http://www.moogparts.com/pdf/problemsolv..._failure_EN.pdf https://www.youtube.com/watch?v=1-FthbeJ-sw Does anyone have experience with this specific Moog product? I am mainly curious about the durability and ride quality. I searched some of the part numbers on Amazon and some folks complained about knocking sounds from this "bushing." Thanks.
