Changed the hub assembaly on the h2 and now it periodically will kick the "traction active" for a few seconds and then after about 10 minutes of driving it throws the "service brake system" and the following lights kick on
1)Abs
2) TC
3) Parking brake


Ideas? maybe the sensor inside the hub that i recieved was bad since it was a rebuilt hub? Does that sensor need to be torqued down to a specific number?

This sucks
Help?

 

i am having the same problem since fitting new hubs
did you sort if so please let me know

 

Just replaced my hub today and got the same problem.

 

Check the abs sensor ring on the rear of the HUB if you dented it or "tweaked" it while reinstalling that might be your issue. Make sure the abs Wires arent pinched anywhere and completely connected. check to make sure the pins are ok on the plug, my driverside was fine but my passengerside was corroded from moisture. I replaced this before driving no problems...

I have also Know of someone getting a hub with a bad ABS sensor right out of the box. it was on a 2500 pickup but it is exactly the same hub.

 

I am having this same problem now. Replaced both my Hub assemblys on the front and the front right locks up for a second and almost throws me into another lane. ABS light comes on and everything. I took the old wire from the old hub and put it on the new assembly to see if maybe it was just the wire from the new hub and it still does this. ABS light comes on after about 3 minutes of driving and the traction control message comes on and my breaking gets kinda of crazy. Does anyone know a common problem? I have looked on many forums and it seems the front right is pretty common issue when replacing the hub assembly.

 

This is something I found on another forum that may help. I am going to try it tommorow and see what happens.

Condition
Some customers may comment on ABS activation at low speeds, usually below 8 km/h (5 mph). Upon investigation, the technician will find no DTCs set.

Cause
The cause of this condition may be an increased air gap between the wheel speed sensor and the hub reluctor ring due to rust and debris built up on the sensor mounting surface.

Correction
Measure AC voltage and clean the wheel speed sensor mounting surfaces.

Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in the General Information sub-section of the Service Manual (SI Document ID #899664).
Disconnect both the front wheel speed sensor (WSS) connectors at the frame and harness.
Place a Digital Volt Meter (DVM) across the terminals of each WSS connector.
Rotate the wheel clockwise approximately one revolution per second. The minimum reading should be at least 350 ACmV's. If the reading is less than 350 ACmV's, remove the wheel speed sensor. Refer to the applicable Wheel Speed Sensor Replacement procedure in the ABS sub-section of the Service Manual. Plug the WSS bore in order to prevent debris from falling into the hub during service.
Clean the WSS mounting surface on the hub to remove any rust or corrosion using a wire brush, or equivalent.

Important
Make sure that the sensor sits flat on the hub. Check the sensor flange against a straight edge to ensure flatness. If the sensor flange is distorted, replace the sensor.


Apply a thin layer of bearing grease to the hub surface and sensor O-ring prior to sensor installation. Use ONLY Wheel Bearing Lubricant, P/N 01051344 (Canadian P/N 993037).
Install either the original sensor or a new one in the hub. Ensure that the sensor is seated flush against the hub. Refer to the applicable Wheel Speed Sensor Replacement procedure in the ABS sub-section of the Service Manual.
Place the DVM across the sensor terminals and recheck the voltage while rotating the wheel. The voltage should now read at least 350 ACmV's.

 

i haad the same exact problem but on front left i am driving it now disconnected, I'm assuming wheel speed sensor replacement will fix? i replace both hubs with no issue but have had the traction active problem ever since... looks like a forty dollar fix???
