Drive shaft rattle

So I've had this rattling sound coming from somewhere under the front. Whenever I would stop there be a light metallic clink like a piece of metal was coming forward and stopping whenever I would drive. And I found out that there is something between the drive shaft and the transmission that has been causing the noise. Any ideas on how to fix it?

 

Its a dirt/rock shield that has come loose. Remove driveshaft and tap it back onto the yoke.

You can add some adhesive or epoxy if you want. It goes on that 1/4-3/8" or so collar at the base of the splined portion.

 

Awesome!! Thanks so much. Gonna get my u joints done at the same time.

Much obliged!

 

Perfect time for new u-joints!
