1. Prepare the vehicle: Park the vehicle on a level surface, turn off the engine, and allow it to cool down. Engage the parking brake and chock the wheels to prevent the vehicle from moving. Disconnect the negative terminal of the battery to prevent electrical accidents.
2. Remove the steering wheel: Use a suitable steering wheel puller to remove the steering wheel. Be careful not to damage the steering wheel, horn button, or wiring during this process.
3. Remove the steering column: Unbolt the steering column from the dashboard and remove it from the vehicle. This may involve disconnecting some electrical connectors and removing any covers or trim pieces that are in the way.
4. Remove the old steering gear box: Unbolt the steering gear box from the vehicle's frame and disconnect any hydraulic lines or hoses that are connected to it. Be careful not to spill any hydraulic fluid during this process.
5. Install the new steering gear box: Position the new steering gear box in place and bolt it to the vehicle's frame. Reconnect any hydraulic lines or hoses that were disconnected.
6. Reinstall the steering column: Reinstall the steering column and reconnect any electrical connectors that were previously disconnected.
7. Reinstall the steering wheel: Reinstall the steering wheel using the steering wheel puller. Tighten the steering wheel nut to the specified torque.
8. Test the steering: Turn the ignition key to the "ON" position and start the engine. Check that the steering wheel turns smoothly and that there are no leaks from the hydraulic lines.
9. Perform alignment if necessary: After replacing the steering gear box, it may be necessary to perform a wheel alignment to ensure that the vehicle's wheels are properly aligned.
It's important to follow the specific instructions and guidelines provided in the vehicle's service manual or by a qualified mechanic to ensure a successful and safe steering gear box replacement.
