I am fairly critical and sensitive to things related to my car. I notice every little noise, squeak, rattle, vibration, etc. I can honestly say that the driveline works perfectly now that the parts have been replaced under the old TSB. I have put over 5000 miles on these parts and the car drives perfectly, quietly, and smoothly. It operates exactly as you'd expect a Lexus to operate.
A few people have asked this same question on this thread, but I haven't seen a response. With the problems Lexus/Toyota have identified with the parts, does this mean that those of us who already had the TSB fix completed will have problems down the line? If so, what kind of problems? What kind of defects did they find in these parts?
