2. NOTE: If the inspection reveals an obvious concern, repair the vehicle.
Do a preliminary investigation. Visually inspect for obvious signs of damage.
1
Inspect the driveshaft:
^
for build up of any foreign material.
^
for damage, such as a bent tube or missing weights.
^
U-joints, CV joints or flex couplers for wear or damage.
