Thank you for responding,
The outer spring has been installed properly by me and again by the dealer. I had the dealer look at it and they could not figure it out. It also seems that the brake pedal feels low and spongy since replacing the pads. This happened prior to replacing the calipers.
If the caliper mounting bolts are misaligned then the pads will also wear unevenly, also try adjusting the rear brakes, which can also cause a soft pedal.
The only other possibility would be the wheel hub bearing causing all the problems.
