OK, well I have a few diffrent problem i need help with...

1. Brakes sound like they are dragging. Every once in a while, it will let out a eye piercing scretch. I changed the rotors and pads with no change. I am stumped.

2. There is a persistant gringing/growling noise while under motion. While at a steady speed it is there, and gets louder when I let off the throtle. It does it when accelerating, and in corners. I changed the front drivers wheel hub assembly, with no change. Could the other Hub have bad bearings as well as both back bearings?

3. Passenger side rotor and caliper was packed with gear oil. I know it is more than likley the axle seal is gone out of that side. just curious if there is any other possibilities.

I have pulled an ABS code for 'WSS low voltage' however, i need to get these other issues taken care of first.

 

First thing I would do is after a drive take a walk around and feel for excess heat on each wheel.

 

I have a similar situation. I am also a heavy breaker so there is a dust issue. Even with ceramic pads I'm thinking the calipers themselves are hanging up...its on my punch list to replace them.
I to also have a fringe sound while under motion. Did a bearing repack and nothing changed...I'm thinking front axle?

 

Did you grease the caliper slide pins when doing the brake job? Its possible the caliper pistons are seized and the calipers need replaced. When the truck is making the noise, start swerving left and right. If it goes away going one direction, then the opposite side has a bad hub. I would also look into the u joints for excessive play and inspect the cv joints.

 

Thank you guys! Well i did grease the slide pins and completely cleaned up the calipers. The brake dust wasnt too bad, except on the right rear which was caught by all the gear oil coming out of the axle seal.

Swerving left and right made no change in the noise. the front is no longer grinding since changing the left fron hub assembly. Now the sound is in the rear...so that tells me two rear wheel bearings. I changed the u-joints two weeks ago due to my thinking that the noise is coming out of those. 223K on original u-joints, could have been the issue... however, they were good?!?!?!?!

Oh, and i found my right rear Parking Brake ring popped lose and was rubbing the inside of the rotor. re hung it and still had the brake noise.

The next work I am going to be doing this week is:
~Change rear wheel bearing
~Change axle seals
~Change Pinion seal
~Change Pinion bearing
~rebuild/replace calipers
