I recently performed suspension work (front upper and lower control arms, ball joints, and strut arms) on my 99 LS400 and am now experiencing a couple problems. We aligned the vehicle to the best of our abilities then performed a zero point calibration which took care of the VSC light displaying, but after driving on it the traction light illuminates. This light pops up intermittently when accelerating from a complete stop or making a turn while driving. And braking to a complete stop it feels as if the right front caliper is locking up almost as if the ABS is kicking on. I am unsure if these problems are related as I have disconnected the front wheel speed sensors from the hub while working on the front suspension. Any thoughts or possible fixes?

 

My immediate thought is to the wheel speed sensor as well

See this thread, there are a few solutions you can try.

New sensors are 150\200 bucks each, yowch!
