No apparent problem with rear brakes on the H3, or the 1/2 ton pickups that use the same system. That doesn't mean it isn't the problem on your vehicle or Hmmmm3. Two vehicles or even 100 times your two vehicles would not affect warranty that much on a vehicle with the sales number the H3 has.
But your symptoms sure sound like mine, and the noise went away with a new t/case.
