1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the battery before starting any electrical work.

2. Check and Replenish Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, add the recommended power steering fluid.
Inspect the fluid for contamination; if contaminated, flush the system.

3. Inspect and Replace Power Steering Pump

Disconnect the power steering pump belt using a socket set.
Remove the power steering pump from its bracket.
Inspect for any signs of wear or damage; if faulty, replace with a new pump.
Reinstall the new pump and reattach the belt, tightening to manufacturer’s specifications.

4. Check and Replace Steering Rack and Pinion

Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheels for better access to the steering components.
Disconnect the steering linkage from the steering rack.
Remove any mounting bolts securing the steering rack and carefully extract it.
Install the new steering rack and reconnect the linkage and bolts.

5. Final Checks

Refill the power steering fluid reservoir with the correct type of fluid.
Start the engine and turn the steering wheel from lock to lock to purge air from the system.
Check fluid levels again and top off if necessary.
