Checking the Steering Gear Bolts Torque
Tighten the steering gear mounting bolt nuts, pitman arm pinch-bolt nut, and steering driveline end yoke pinch-bolt nuts to the specifications in Table.. See Fig. and Fig.. After the end yoke pinch-bolt nuts have been torqued, apply white Torque Seal F900 to the exposed pinch-bolt thread and locknut.

If the steering driveline end yoke pinch-bolt nut(s) is loose, disassemble and check the input shaft serrations, upper column and jacket assembly wheel tube shaft serrations, and steering driveline end yoke serrations for wear or damage. If worn or damaged, replace the parts as necessary, following the instructions, see of the Walk-In Van Chassis Workshop Manual, or take the vehicle to an authorized Freightliner dealer.
Warning: Failure to tighten the steering gear pinch-bolt nuts to the recommended torque value could cause disengagement of the components and loss of steering control, possibly resulting in personal injury or property damage.
