joelol75 12/3/2012Is it the ABS engaging? Does it sound like a buzzing motor turning on while breaking in a turn? If so, you may have a break in the speed sensor wire that may have been aggravated by the brake job. There is a pigtail coming out the back of the hub that goes to a plug mounted on the strut. It then traverses the A arm. Disconnect the plug and hook up an ohmmeter to the hub side. It should be somewhere in the neighborhood of 800-1200 ohms. It shouldn't be an open or dead short, but since you have no abs codes, I'd suspect an intermittent open. If its reading OK, make sure to bend the wire while testing to see if there is any intermittent breaks. If there is, you have two options. Replace the whole hub assembly /VSS......or what I did, chop and solder new wire in. Use high quality, fine stranded copper wire. Also make sure it doesn't rub the CV area (the place where the pigtail exits moves!!!). And the real challenge... Check through entire range of steering for rubbing.
IMO this is a sh1t design to expose cheap aluminum wire to continuous bending, then mount the plug in the freakin' worst spot where snow/ice chunks and roadcrap hits it.
Anyway I had this problem and it didn't throw codes either.
If it's not a abs vibration, maybe the wheel mounting surfaces are not clean. Maybe the lugnuts weren't torqued in steps in the proper order. Maybe the old rotors were reused and have a taper... This was an old post, hopefully you ripped it apart to rectify.
