Question 6

F-377 Bi-Monthly Preventive Maintenance

Steering Box and Steering Linkage

(Engine shut down). Position front wheels straight ahead
(wheels on ground). Have an assistant move the steering wheel back and forth with short ( __ to__ ) rapid movements. At the same time inspect steering linkage and connections for any looseness or excessive movement. You can place your finger on the two mating parts of each steering connection and “feel” for any disproportionate movement between the two. Any detectable movement should be noted and reported. The following steering components can be checked in this fashion:

 Steering box input shaft/slip joint/u-joints.

 Steering box mounts.

 Steering box output shaft/Pittman arm.

 Pittman arm/drag link ball joint connection.

 Draglink/steering arm ball joint connection.

Question 9

F-377 Bi-Monthly Preventive Maintenance

Drive Line

Park apparatus on level surface, chock wheels and release
parking brake. Inspect drive line(s) tubes for damage (cracked welds, bending, misalignment). Inspect driveline u-joints for wear/looseness. The most effective procedure is to position yourself directly under the u-joint, place both hands on the end of the drive line tube next to the u-joint and try to move the tube up and down. Try to observe or “feel” for any measurable up and down movement. If any movement is detected it should be noted and reported. Any excess movement in the road transmission and drive axle bearings can be detected in this manner. Check all drive lines and u-joints in this manner.
