Had a terrible sound this morning. Pulled out of the garage, drove about a 1/10th of a mile, stopped at the stop sign, turned right onto the main road. . . .then all of a sudden. . . .grind, grind, grind noise from the right rear, pulled over to the shoulder placed in park, thought I had caught something under the vehicle. . .nope. . .proceeded another 1/10th of a mile, still making the noise. Stopped and put on the parking brake. Got out looked again this time much closer feeling around the tire and wheel well. . .nothing. Hopped back in drove back home, the noise was getting weaker. Backed in the garage and then got completely underneath the vehicle looking at the drive train and wheels. . .nothing. Hopped back in and started driving up the street, no noise, nothing. I have just over 3K miles on the vehicle. Do you think it may have been a caliper sticking? Sure sounded alot like pads rubbing on the caliper. Your thoughts? Thanks for reading.
