ABS, Front wheel bearings
Need repair manuals
Also sold under the GMC Sierra and VIA Vtrux names, available in the US, Canada, Mexico and other countries around the world.
I believe most auto shops will carry the manuals for silverado trucks. If you live in the US then autozone, checkers/oreily, pep boys they will most likely have them. Probably published by Haynes or Chilton. Check over at FixYA.com to see if they have any other info on your Chevy they have much more automotive stuff there.
laurablake2006, until you get the manual here is some idea how to do it Raise and support the vehicle. Remove the tire and wheel.Remove the rotor.Remove the wheel speed sensor and brake hose mounting bracket bolt from the steering knuckle. Remove the wheel hub and bearing (number 4 in the diagram)Remove the wheel hub and bearing and splash shield from the vehicle.Remove the O-ring seal from the steering knuckle bore, Remove the wheel speed sensor mounting bolt(5).
Clean and inspect the O-ring seal. This might get you going until you get a better idea. The manual is available in many places like XnriquX pointed out, even your local library might have a copy. Do a good Google search and there is lots of information out there. best information I found for the Chevy's is this forum Good Luck
in my experience repair manuals such as the ones published by haynes or chilton are pretty much worthless and you will find more info on google. The instructions are very generic and typically end with something telling you to reverse the directions for re installation. Now service manuals on the other hand are very helpful you will know the difference because they are much thicker and cost much more. Also consider all data http://www.alldata.com/ As far as your repair, do you have a wheel bearing issue or a abs issue? If you need the wheel bearing replaced you will want to get the whole hub assembly if its an issue with the wheel speed sensor than you can replace that by itself. My 05 Silverado 2500 is at 285k and both from wheel bearings have failed twice now, I just change out the whole hub.
