What did you do to your truck?
Moving the transmission effects the front shaft.
Moving the suspension effects the rear shaft.

Coil trucks don't have as big of a problem as leaf trucks when it comes to the driveshaft changing length with suspension droop and compression.

5" drop coils on.the back with the adjustable trac bar. PO lowered the front by heating the fronts ( to much) c downs. You just trimmed the yoke? Wouldnt the shaft need trimming?

If the rear shaft pushes the carrier bearing that far through the carrier mount you should cut, weld, the rear shaft and reballance. Some yokes are long enough to hit the speedo gear, its best to counterbore the yoke IF the yoke is too long.
Ill assume your shaft was correct before lowering, the rear shaft needs to be shortened.
