Is there some way to test the carrier on the 2 piece driveshaft for the 157” wheelbase trucks? I’ve been getting some vibration and clunking. I know these fail and are non serviceable but don’t know how to test them. The shaft moves up and down in the carrier but the rubber surrounding it looks fine. Truck is a ‘13 f150 5.0 157 wheelbase.

Anybody know how to do this?
