Was wondering the exact hub assembly I will need for my 2000 SS. I have come across some that has a steel sensor wire clip...what is that and will I need that particular assembly for mine. Thanks.

 

Timken seems to have the best wheel hubs out there according to reports from others on this forum. Most replacement hubs include the sensor and clip that you should replace. The Timken part# is 513121for 2000 SS. Available through Rock Auto and just about everywhere else.
