Does it happen when you turn the steering wheel? Do you have power steering? Check your tranny fluid also.

Last time I was in your area, there were tons of Chevy sedans running around. Maybe it's time to drop a small block into your truck. Parts will be more available.

after removing the engine we find the problem. first problem is with the harmonic balancer was not set tight due to a crack in the center......:smoke:
the second problem is with the flywheel, because the harmonic was not set tight it cause a vibration and that vibration affect on the screw on the flywheel and make them to lose......al:bann:l fixed and i'm happy
