After CM08 I had Drew take the FJ for a spin as I was hearing a ticking noise in the drive train along with a faint whine when decelerating. Long story short; Toyota is is replacing the entire 3rd member. Two teeth chipped of the ring gear. June 06 build model and known to have issues. Want to thank Drew as this old farts hearing isn't what it used to be and Kudos to Toyota for doing the right thing.
... I'm just hoping it dosn't fail on the trail.
