New Wheel Bearing Hub Assy Install, ABS now activates

[SAE09]

The RH front wheel bearing was shot @ 150k on my 99 K2500 4x4. Easy task to replace, just time consuming.

Using all the correct tools and torque specs as well as care to clean

surfaces prior to reassembly.

 

Having installed a new Driveworks wheel bearing hub assembly (Advnced Auto Parts), my ABS now activates once my speed drops between 15 & 10 mph regardless of road surface or using the brakes. It does the same in reverse. The ABS does work correctly at various speeds.

 

Is this something that can occur with an assembly like this in the event the
sensor is not manufactured correctly?

I will be trying a replacement sensor / harness this weekend and if that
does not work then the wheel bearing hub assembly will be replaced.

Any experience with symptoms like this? Thank you SAE09

Wanted to follow up here.

 

Defective sensor ......... replaced with a new sensor, same brand, works fine.

The defective sensor had a short at the point of attachment to the wheel bearing hub flange.

Tested the sensor harness in the electronics lab at work.

 

Funny that it never pulled any codes while it was installed, yet it was malfunctioning, nor did I get a light.

 

Thank you for reading.

Did you have a scanner capable of reading ABS codes?
