Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, and a pry bar.
Allow the vehicle to cool if it has been running.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle.
Secure the vehicle with jack stands to ensure stability.

3. Inspect the Steering Rack

Locate the steering rack and visually inspect it for signs of damage or excessive wear.
Use a pry bar to gently apply pressure to the rack to check for play.

4. Check Tie Rod Ends

Examine the tie rod ends for any excessive play or damage.
If play is detected, replace the tie rod ends as necessary.

5. Tighten Mounting Bolts

Using the appropriate socket, check and tighten all mounting bolts securing the steering rack.
Refer to the service manual for the correct torque specifications (typically around 30-40 Nm).

6. Reassemble and Lower the Vehicle

Remove the jack stands and lower the vehicle using the jack.
Ensure all tools are removed from the work area.
