If leaks are found at the steering rack, assess whether it needs replacement.
Disconnect the steering column from the rack.
Remove the tie rod ends from the steering rack using a tie rod puller.
Unmount the steering rack from the chassis and disconnect fluid lines.
Install the new steering rack by performing the steps in reverse order.
Reconnect all components securely.

5. Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Use the correct power steering fluid (refer to manufacturer specifications).
Fill the reservoir to the recommended level.
Start the engine and turn the steering wheel from lock to lock to circulate the fluid and remove air.
