Noise coming from rear axle.

Hey guys,
Once again I need some advice before I tear in the my truck and not know what I'm doing. I've had a noise coming from my rear axle for some time now. I just realized where it originated from after trial and error changing fluids from my transmission back. And today I finally put it on jack stands and heard the the noise is coming aboutat my wheels on my rear axle. I checked the condition of the pads and rotors and they seem to look good and have some life left in them. I just want to know what to look for when I get the chance to take it apart. Thanks fellas.

can be drag in the brakes , emergency, or backer plate..... if not that, you could have a bad wheel bearing..... narrow it down with brakes removed.... see if there is radial clearance in the bearing by lifting wheel.... there should be 1/ 16 inch end shake ( approx.)..... your looking for up / down clearance.

If its a roar its probably a wheel bearing. Sometimes they will click when turning the wheel. Some rear wheel bearings on trucks are lubed by the gear oil and some are packed with grease. If the bearing cut the axle you'll need an axle too.

Mine was making a noise, and it turned out to be the pinion bearings. It cost me about $590 dollars to have a local shop fix it.
