MAINTENANCE Steering Inspection / Tie Rod Ends and Hubs Toe Alignment Inspection To check for play in the tie rod end, grasp the steering tie rod and pull in all directions feeling for movement. 1. Place machine on a smooth level surface. 2. Set steering wheel in a straight ahead position and secure the steering wheel in this position. 3. Place a chalk mark on the center line of the front tires approximately 10” (25.4 cm) from the floor or as close to the hub/axle center line as possible. Measurement “B” Chalk Mark Measurement “A” Elevate front end of machine so front wheels are off the ground.
Check for any looseness in front hub and wheel assembly by grasping the tire firmly at top and bottom first, and then at front and rear. Try to move the wheel and hub by pushing inward and pulling outward. NOTE: It is important that the height of both marks be equally positioned in order to get an accurate measurement. 4. Measure the distance between the marks and record the measurement. Call this measurement “A”. Check for Loose Wheel or Hub 5. Rotate the tires 180 ° by moving vehicle forward or backward. Position chalk marks facing rearward, even with the hub/axle center line. 6. Again measure the distance between the marks and record. Call this measurement “B”.
Subtract measurement “B” from measurement “A”. The difference between measurements “A” and “B” is the vehicle toe alignment. The recommended vehicle toe tolerance is 1/8” to 1/4” (.3 to .6 cm) toe out. This means the measurement at the front of the tire (A) is 1/8” to 1/4” (.3 to .6 cm) wider than the measurement at the rear (B). If abnormal movement is detected, inspect the hub and wheel assembly to determine the cause (possible loose wheel nuts or loose front hub components). Refer to Chapter 7 “Final Drive” for front hub service procedures. Wheel Toe-Out: (A) - (B) = 1/8 - 1/4" (.3 to .6 cm) 2.28 = In. / mm.
