Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
hi there, I am Cam. Can I get your first name pleasE?With your noise, where do you hear it from? Does it happen repeatedly? Does the frequency of it change with speed? Load?
Does it bang like something hitting the wheel? Does applying the brakes aside form the normal change when slowing down change it?
Ok, I would look to an issue with the drive shafts then or mounts. What I suggest is you lift and support the vehicle. Then start the truck and put it in gear, let it idea and watch the drive shaft. See if there is any hoping, bends or movement.If that is good, remove the drive shafts and check for tight u-joints or stiff movement. Check the engine and transmission mounts to see if any are loose. Check for loose shocks.
Run it lifted though, watching the shaft movement.
Ok, let me know.
