2007 Toyota Sequoia
Recently I was stuck in highway traffic. This caused a lot of stopping and starting. Later I began to hear 'clicking' noises coming from the rear wheels. Parked the car for the night. Next morning the noise left. Another day I was freeway driving in the rain, I began to hear that 'clicking' noise again. What's happening? Are the wheels going to fall off? I must note that the tread on the tires are getting low. I'm planning to replace all 4 within the next month. 4Wheel Drive. Please advise?
