Re: Warped Rotors

Remember that Bentley says to replace control arm bushings after 40k
miles to eliminate shimmies. (Doesn't always work, but worth checking.)
I have seen poor turn jobs where the rotors  were not true afterwards.
Possibly your rotors have been turned when or until they are under
sized. Your hubs may not be true. I have seen over tightened lug bolts
distort a rotor. (Others have argued against this theory, but it did
happen on my mom's '73 VW van.)
