The steering box is a sensitive and critical component of your car. If you need to replace this part, it is important to prepare the right tools and instructions before starting the process. The steps required for replacing the steering box step by step;
Preparation Stage
First, loosen the lug nuts of the right and left wheels of your vehicle. This process should be done while the vehicle is on the ground.
Then, use a jack to lift the vehicle from one side and place the jack stand on the appropriate chassis connection.
Apply the same procedure for the other side, suspending the vehicle completely.
Removing the Wheels
Completely remove the lug nuts of both front wheels and detach the wheels from the vehicle.
Disconnecting the Steering Column Connections
Loosen the nut of the steering column connection and remove the bolts of the outer connection group.
Removing the Tie Rod Connection
Loosen the ball joint nut at the end of the tie rod and separate it from the socket using a plastic hammer.
Accessing the Steering Box Mounting Bolts
Remove the necessary parts to access the steering box mounting bolts, connection lines, and steering connection.
Disconnecting the Hydraulic Connections
Place the oil pan under the vehicle and disconnect the hydraulic pressure hose and return hose from the servo connection.
Checking the Compatibility of the New Steering Box
Check the length of the new steering box and the direction of the connection holes. If needed, adjust the tie rod ends to equalize the sizes.
Installing the Tie Rods
If using old tie rods, loosen the nuts and mount them to the new steering box with the same number of turns. Check the total length and adjust if necessary.
Connecting the Power Steering Lines
Reconnect the high-pressure and return lines. Secure both lines using new sealing rings. Ensure the lines are mounted with the correct sealing rings.
Reinstalling the Steering Column Connection
Mount the steering column connection piece to the new steering box and securely bolt both components.
Reassembly of the Tie Connections
Reattach the ball joints at the ends of the tie rods to the steering knuckles. Use new cotter pins to secure these connections.
Installing the Wheels and Tightening the Lug Nuts
Install the wheels and tighten the lug nuts to the torque values recommended by the manufacturer.
Filling and Bleeding the Hydraulic System
Fill the steering hydraulic fluid and run the engine to allow clean fluid to flow from the return line.
Run the engine at idle and turn the steering wheel fully to the right and left to bleed the air from the system. Be careful not to turn the steering wheel to the maximum.
Turn off the engine, wait for a while, and check the hydraulic fluid level. Add fluid if necessary.
Test Drive and Final Checks
After completing all the steps, take the vehicle for a test drive. Check the comfort and response of the steering.
After driving, check for any oil leaks in the steering box.
These steps cover the basic process of steering box replacement. It is important to follow each step carefully and pay attention to your vehicle´s specific requirements. In case of any doubt, leaving the process to a professional is the most reliable option.
