Re: Rear Brake/Axle Groan...
Hummmm.... Mine does this too. 14k miles. Thought it was just rust on the rotors or something. Seemed like it went away with a really hard brake for me... But it does/has come back on and off. I'll be watching this thread to see what you guys find out.

Re: Rear Brake/Axle Groan...
Note:: Remember do not operate the vehicle in unlock (4hi) mode on the hoist as damage to the planetary gear set may result due to an over speed condition.
Does that mean you can operate it in 4 hi lock or 4 low lock up on the lift?
I would think it will also due damage.
when I go to bed and shut my eyes and its all quite. I hear grrr grrr grrr
Its stuck in my freekin head

Won't cause an overspeed condition. Besides, the sound is not noticeable on a hoist. Has something to do with the dynamic weight shifting during heavy braking. My guess, it might be a shift fork...

Believe me, if it was the t/case, the noise would not go away with a very hard stop. Rust on the rotors will do this, but once burned off, the noise will go away. Rotors are cast iron, so rust while sitting in a rain storm is normal. But applying the brakes will burn off the rust on the firepath.
