All special tools are listed below. Ball Joint Removal Tool (1.0-1.5” (25.4-38.1mm): Needed for removal of tie rod ends from the strut casting steering arm. Ball joint removal tools are commercially available in various sizes. SAFETY FIRST CAUTION Never work underneath a raised vehicle without adequate support. Use jack stands to prevent the vehicle from falling. A falling vehicle can cause severe personal injury or death. CAUTION When lifting a vehicle chock the wheels left on the ground to prevent the vehicle from rolling or sliding backward. BUSH HOG® UTILITY VEHICLE WORKSHOP MANUAL – SECTION 7: STEERING SYSTEM DESCRIPTION STEERING The UTV rack and pinion steering (Figure 1) is common in many automotive systems. The rack is a flat gear that extends outward from both ends of the assembly. A tie rod end connects the rack to the suspension strut assembly. NOTICE: The suspension struts are described in the Suspension Section of this manual. The pinion is a rotary gear attached to the steering shaft assembly. When the operator rotates the steering wheel the steering shaft turns the pinion gear which drives the rack in a back and forth movement. The rack and pinion gear set converts rotary steering wheel motion into linear motion needed to turn the wheels. The rack and pinion also provides gear reduction making it easier to steer the machine. The tie rods connect to a steering arm on the struts used for turning the strut. The wheels and hubs are mounted to the strut. See the section entitled Suspension for a description of the strut assemblies.

Complaints of steering wheel hard to turn, hard steering, or loose steering can be a result of a bad pinion gear, bad rack, or bad tie rod ends. Use the recommendations in the operator’s manual for initial testing. Inspect the rack and pinion and tie rods for worn, loose, or damaged parts. Check for excessive wear in the steering bracket and upper steering shaft. Inspect the upper and lower steering shaft U-joints for excessive wear and damage. Replace the steering bracket bushings, steering bracket, upper and lower steering shafts as needed. REMOVAL CAUTION When working underneath a raised vehicle, always support the vehicle with jack stands to prevent the vehicle from falling. A falling vehicle can cause severe personal injury or death. RACK AND PINION REMOVAL 1. Using a floor jack, lift the machine and support with jack stands. 2. Turn the steering tires all the way right. 3. Remove the cotter pin from both tie rod end slotted hex nuts. Discard cotter pins. 4. Remove both tie rod slotted hex nuts (Figure 2).
