Solution

1. Preparation

Gather tools: socket set, torque wrench, inspection mirror, flashlight.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; if low, top up with manufacturer-recommended fluid.
If fluid is discolored or contaminated, drain the old fluid, replace it with new fluid, and bleed the system according to the service manual.

3. Inspect Steering Components

Remove the under-dash cover if necessary to access the steering column.
Inspect the universal joints and couplings for any signs of wear or damage.
If any components are damaged, replace them as needed.

4. Lubricate Steering Joints

Identify all grease fittings on the steering rack and joints.
Use a grease gun to apply a manufacturer-recommended lubricant to all fittings.
Wipe away any excess grease to prevent debris accumulation.

5. Reassemble and Torque

Reassemble any components that were removed during inspection.
Use a torque wrench to tighten all bolts to manufacturer specifications as outlined in the service manual.

6. Reconnect Battery

Reconnect the 12V battery, ensuring the terminals are secure.
