Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure with jack stands if elevated.
Disconnect the battery to prevent electrical shorts.

2. Inspect Steering Rack

Tools Required: Flashlight, clean rags, and a fluid catch pan.
Sub-steps:
1. Use a flashlight to inspect the steering rack and its connections for any signs of fluid leakage.
2. Wipe the steering rack with a clean rag to remove any dirt or old fluid, making new leaks easier to identify.
3. Pay attention to the seals and boots at the ends of the rack for wear or cracking.

3. Check Power Steering Fluid

Tools Required: Funnel (if adding fluid).
Sub-steps:
1. Remove the cap from the power steering fluid reservoir.
2. Check the fluid level against the markings on the reservoir.
3. Inspect the fluid's condition; it should be clear or slightly tinted. If it is dark or contains debris, it may need to be replaced.

4. Perform a Leak Test

Tools Required: None.
Sub-steps:
1. Start the engine and turn the steering wheel from lock to lock several times.
2. Observe the steering rack and connections for any signs of fluid seeping out during this motion.
3. If leaks are found, identify the source (e.g., seals, hoses) for further action.
