Update on rear brake/axle sound .. whine sound ...

[StarsnBars]

Mine doesnt make that sound at all and Ive hit the brakes hard abunch of times. Question,,, Can the ABS need adjusted? I dont know much about ABS stuff and maybe a GM guy in here can help answer this question. Just a though, I know its not much, just tryin to help.. Good luck, keep us posted..

check to see if the noise-whine-grind-sounds the same, or disappears, on pavement and then on dirt-trail......

tryed on mine to see if i get anything.
Tryed several times, actually went into a skid on one and the abs kicked in.

Other than the pulsation of the ABS i didnt feel or hear anything else.

It could be tires, depending on what type of tire you have you will get a little ground noise from the tread on the offroad tires. This is just a guess on my part but Ive owed a few offroad vehicles and different tires do different things at the last few revolutions before stopping. Try having them spin balanced and rotated, my Hummers new and I want to get the tires rebalanced, I dont think the manufacturer does good with the Firestone 285 tires.

I thought I'd bring this old thread back to life to see if anyone had figured this out. I had something happen today for the first time. I slammed on the brakes hard and hear a grinding sound exactly like the pads had worn out and were eating the rotors. It only happens under hard braking and only in the last second or so before the truck comes to a complete stop. The sound comes from the passenger side rear. I've read about the other post with the ratcheting noise and the transfer case... This is not the same sound. (By the way... Kudos to the people who posted those sound clips!)

I only have 14k miles on the truck and have a hard time believing that the passenger side rear would wear out first. I checked out the rotors and didn't see where the pads have worn and or scored the rotors.

Any ideas?
