im having a skeaky noise coming from the rear when I stop abruptly. could it be the rear shocks? I had the rear right replaced under warrenty last winter. maybe it is the other one. damn mazda why wouldn't they replace both rear shocks instead of one. I am getting quite alot of noise coming from the rear when I go over rough spots in the road. could it be the bushings or sway bar? also

 

Do you have a sunroof ? I found that when I went over bumps with the sunroof closed, the rubber seal rubbed against the body. I put some grease on there and it stopped...just a thought.
