Engine To Frame Ground
Inspect engine ground cable connection. Be sure it is
clean and tight. The ground cable runs from the engine
starter motor to the ground terminal location under the
driver’s seat.
STEERING
Steering Inspection
The steering components should be checked periodically
for loose fasteners, worn tie rod ends, ball joints, and
damage. Also check that all cotter pins are in place. If
cotter pins are removed, do not re–use, always use new
cotter pins.
Replace any worn or damaged steering components.
Steering should move freely through the entire range of
travel without binding. Check routing of all cables, hoses,
and wiring to be sure the steering mechanism is not
restricted or limited.
NOTE: Whenever steering components are
replaced, check front end alignment.
Steering Wheel Freeplay
Check the steering wheel for specified freeplay and
operation.
1. Position the vehicle on level ground.
2. Lightly turn the steering wheel left and right.
3. There should be 0.8”-1.0” (20-25 mm) of freeplay.
4. If there is excessive freeplay or the steering feels
rough, inspect the following components.
• Tie Rod Ends
• Steering Shaft U-Joints
• Steering Gearbox
