Thanks for the opinion/guidance. I have been getting some "push back" from a few mechanics that replacing the bushings on perfectly good control arms (IMO) can "mangle" or damage the arms. I agree with you. How difficult is it to replace them for a skilled mechanic?
Also, rubber vs. urethane. Does urethane result in a stiffer/harder ride? Does it have greater longevity?
All the parts look like Lexus OEM, yes. Cost?
BTW, I just replaced rotors, calipers, pads, and inner/outer tie rods on my son's Honda Pilot--I am capable and versed.
