1992 Chevrolet Cheyenne

When I turn off my engine it makes a rattling noise down under the truck. Could anyone tell me what is it? Has it happened to one of you guys?

Possible heat shield, exhaust not in proper alignment, support bracket not supporting. Get somebody to keep turning off the motor and find what part of the vehicle is making noise. Don't be afraid to get on your hands and knees.

 

Report back.

I believe I have solved the problem. It looks like there is a couple of bolts missing to the transmission. That could be the probabale rattling noise.
