Okay I got my 3.73's installed the other day now my gears make the stange sound whne you release the gas pedal and coast a little. They make this sound like it's winding down wwoooooooo. Is this normal or has the backlash been set to deep?
Normally gear whine will occur at a certain speed range. If you started hearing this noise RIGHT after the gear install, the gears are probably whining.
