Driveshaft Inspection

Inspect the driveshaft for any undercoating, physical damage and missing balance weights. Check for index marks (yellow paint daub marks) on the rear of the driveshaft and the axle pinion flange. The paint daubs must be less than 22-1/2 degrees apart.

Place the vehicle on a frame hoist and rotate the driveshaft by hand. Check for rough operation or seized U-joints. Install a new U-joint if it shows signs of seizure, excessive wear, or incorrect seating.
