3. How to Fix John Deere L120 Steering Problems
3.1. Tighten the Steering Wheel
If your steering wheel is loose or wobbly, the first thing you should do is check to see if any bolts or nuts are loose. If you find any, tighten them with a wrench or socket set. This should fix the problem, but if the issue persists, it may be necessary to replace the steering wheel entirely.
3.2. Check the Steering Gear Assembly
If your steering wheel is stuck or difficult to turn, it’s likely that there is a problem with the steering gear assembly. This can be caused by worn-out gears, damaged bearings, or a broken steering sector plate. To fix this issue, you will need to disassemble the steering gear assembly and replace any damaged components.
3.3. Check the Tie Rod Ends
If your steering wheel turns unevenly, it could be an indication that there is a problem with the tie rod ends. These are the components that connect the steering system to the wheels. If they are worn out or damaged, they can cause the steering to turn unevenly. To fix this issue, you will need to replace the tie rod ends.
3.4. Check the Steering Shaft
If your steering wheel turns unevenly or is difficult to turn, it could be an indication that there is a problem with the steering shaft. This component connects the steering wheel to the steering gear assembly. If it is worn out or damaged, it can cause the steering to turn unevenly or become difficult to turn. To fix this issue, you will need to replace the steering shaft.
3.5. Inspect the Steering Sector Gear
If your steering wheel is stuck, it’s likely that there is a problem with the steering sector gear. This component is responsible for transferring the movement of the steering wheel to the steering gear assembly. If it is damaged or worn out, it can cause the steering to become stuck. To fix this issue, you will need to replace the steering sector gear.
3.6. Check the Steering Sector Plate
If your steering wheel is stuck, it’s also possible that there is a problem with the steering sector plate. This component is located on the bottom of the steering gear assembly and is responsible for holding the steering sector gear in place. If it is broken or damaged, it can cause the steering to become stuck. To fix this issue, you will need to replace the steering sector plate.
3.7. Check the Front Wheel Bearings
If your steering wheel shakes while in use, it’s likely that there is a problem with the front wheel bearings. These bearings are responsible for allowing the front wheels to turn smoothly. If they are worn out or damaged, they can cause the steering wheel to shake. To fix this issue, you will need to replace the front wheel bearings.
3.8. Check the Front Axle
If your steering wheel shakes while in use, it’s also possible that there is a problem with the front axle. This component connects the front wheels to the frame of the mower. If it is damaged or worn out, it can cause the steering wheel to shake. To fix this issue, you will need to replace the front axle.
3.9. Replace the Steering Wheel
If you have tried all of the above solutions and your steering wheel is still loose or wobbly, it may be necessary to replace the steering wheel entirely. This can be done by removing the old steering wheel and installing a new one.
