gt40gordy If you have a car lift, put the car on the lift and run it and listen for the noise. A long screwdriver in your ear works good too start. If you don't have a car lift to use, 4 good jack stand under each corner of the suspension. The front lower control arms and the rear ones as far out as possible without hitting the tires. This keeps the drive drive at a better angle to run. Run the car up through the gears until you hear the noise and locate. If you think it is the brake pads, this noise comes and goes when the brake pedal is pressed. If noise still there look for any looseness in the hubs for the wheels. Hub bearing may be going bad. If you heard or find no play, you are down to the final drive or the trans if the car is a GT-40. It sound like you have a broken rearend or teeth missing on the pinion or ring gear. Take a fluid sample from the rearend and look at the color. If it comes out with a silver or metal color, you found your problem. If not unhook outter shafts to wheel hubs and spin them and listen for noise. Put or leave tires on them for weight and load. Stop here. You might have to go to a garage or get a good mechanic to look at the car. Does any one live near you with a GT or Cobra?? Good luck Rick L.
