Remove any components obstructing access to the steering rack bushings.
Use a wrench to remove the old bushings from the steering rack.
Install new bushings, ensuring they are seated correctly.
Reattach any components removed for access.

5. Check and Adjust Tie Rod Ends

Inspect the tie rod ends for wear; replace if necessary.
If they are in good condition, ensure they are secured and adjust to correct alignment if needed.

Reinstall any removed components and ensure everything is secured.
Carefully lower the vehicle from the lift or jack stands.
