Disconnect the battery to ensure safety during repairs.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the recommended fluid if low.
If the fluid appears dark or contaminated, proceed to flush the system.

3. Inspect and Replace Power Steering Pump (if faulty)

Tools Required: Socket set, torque wrench, fluid catch basin, new power steering pump, power steering fluid.
Remove any components obstructing access to the power steering pump (e.g., air intake duct).
Disconnect the fluid lines from the power steering pump using the appropriate tools.
Unbolt the pump from its mounting bracket and remove it from the engine bay.
Install the new power steering pump by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications.
Reconnect the fluid lines, ensuring they are secure and leak-free.

4. Inspect and Replace Steering Rack (if necessary)

Tools Required: Socket set, torque wrench, new steering rack, power steering fluid.
Disconnect the steering column from the steering rack.
Remove the tie rod ends from the steering knuckles.
Unbolt the steering rack from its mountings and slide it out.
Install the new steering rack, reattaching it securely and adjusting the tie rod ends as necessary.
Reconnect the steering column to the new steering rack.

5. Refill and Bleed Power Steering System

Fill the power steering reservoir with the appropriate fluid.
Start the engine and turn the steering wheel fully left and right several times to bleed air from the system.
Check the fluid level and top off as needed.
