Review on Timken SP550307 Axle Bearing and Hub Assembly: Superior Performance for Smooth Axle Operation by David Dreher

Revainrating 5 out of 5

2 of these for the best price I could get 1 OEM (Delco).

Many GM 4x4s with an ABS sensor in the hub and bearing offer anti-lock braking when it is not needed on dry roads and you collide with another car in a parking lot. These bearings are quiet and the problem of accidental anti-lock braking is gone. I chose Timken because I think they make quality products.

Pros
  • Easy Service
Cons
  • Appearance
