Squish/crunch sound from rear passenger wheel ...

[Hmmm2]

When I begin to slow down coming to a stop, I hear and feel a sort of squish/crunch sound coming from the rear passenger wheel. I have a little over 13,000 miles on my H3. It doesn't happen on quick short stops .. only when I give myself distance to stop. Does anyone know what this could be? I'm going to the dealer in the morning. (I also have a problem with the passenger seat belt not releasing itself after the brake pedal is released, keeping the passenger feeling like he/she is in a straight jacket until they remove their seat belt and re-click it.) By the way, they had had my H3 last week for a cyclinder head/valve replacement .. another time for tire pressure sensor message light. Thanks for any advise! (First timer here)
