Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to prevent electrical issues.
Raise the vehicle and secure it on jack stands for safety.

2. Identify and Repair the Leak

Power Steering Reservoir:
- Remove the cap and inspect for cracks.
- Replace the reservoir if damaged.
Hoses:
- Loosen the clamps on the power steering hoses using a socket set.
- Remove the hoses and inspect for cracks or wear.
- Replace any damaged hoses with new ones, ensuring they are properly routed.
- Reattach the hoses and tighten the clamps to manufacturer specifications (typically 8-12 Nm).
Power Steering Pump:
- Remove the drive belt from the power steering pump.
- Unscrew the bolts securing the pump and carefully remove it.
- Inspect the pump seals for wear or damage.
- Replace the pump if leaks are found; otherwise, reassemble with new seals.
Steering Rack:
- Inspect the steering rack boots for tears, which can lead to fluid loss.
- If leaking, replace the inner tie rod ends and steering rack as necessary, following manufacturer guidelines for alignment afterward.

3. Refill and Bleed the System

Refill the power steering reservoir with the appropriate fluid (typically ATF or manufacturer-specified fluid).
Start the engine and turn the steering wheel back and forth several times to bleed air from the system.
Check fluid levels and add more if necessary.
