2003 impala

[octobersman04]

I just recently had a front wheel bearing replaced on my 2003 impala LS, that took care of the trac and ABS lights but now I am finding my ABS brakes system arppears to be engaging when I come to a stop or turn the wheel sharply, pulsation can be felt in the brke pedal and the moan can be heard from the front it happens even when I back out of the driveway, I have a ob2 but nothing shows up and there are no warning lights to indicate further problems. I should mention the front bearing was replaced by a licenced shop and they never indicated further problems existed other than the bearing, responses appreciated in advance.

Thanks
Jim

Welcome to AF. Jim, you must have this scanned with an abs function scanner, looking at wheel speed sensor inputs when this occurs will usually reveal a bad speed sensor at one of the wheels, at low speeds the input to abs controller is lost so it thinks a wheel is locked.

Thanks Maxwedge turns out it was the sensor harness also know as the sensor kit.
