i just replaced my front wheel bearing hub with the Timken on my 09 ss tc.
Part number HA590070. But now the car goes crazy when I drive it. The esc comes on and says low traction. It also makes a weird noise a buzzing noise. I did connect the abs back. I check a million times. Please help. What can it be?!?!? Esc active when I break

 

Gotta be a defective part if you re-connected everything.

Take it back and get another one. Make sure it's for the right year car, the earlier ones will physically fit the car but the sensor ring frequency is different.

 

I took the tire back off and inspected it. Everything looked fine. I disconnected the abs and connected it back. I then put the tire back on and drove it one more time. At first it did the same thing. Skipped when I was breaking. I then turned off the esc and traction control off. Drove it for a bit, then turned it back on and I began to drive like normal. Now it's not giving me any problems. I'm still wondering what it could have been.

 

I'd guess a poor connection in the sensor or some contamination in the wiring. Hard to say though, without seeing the wheel speed readouts on a scanner when it's happening. Glad it's working better now though.

 

My ABS went bananas when I did my wheel hub, turns out the metal ring wasn't seated properly (first time doinng this) ...took it all apart and grinded the notch where the ABS sensor plug fits into the strut or whatever its called so it fit better and and made sure the ABS ring was snug when I put i all back...anyways its fine now.

OP if everything is hooked up right and that ABS sensor ring is correctly attached and its still doing it then the part must be defective.

BTW when I say ABS ring I mean that piece that the ABS sensor cable is attached to.. its a metal ring thats detachable from the hub, mine wasn't seated correctly
