Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the reservoir cap and check fluid level and condition.
If the fluid is low or dirty, drain the old fluid and refill it with the manufacturer-recommended fluid.
Start the engine, turn the steering wheel from lock to lock to circulate the new fluid and check for leaks.

3. Inspect and Replace Worn Suspension Components

Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheels to access suspension components easily.
Inspect control arms, tie rods, and bushings for wear. Replace any damaged parts.
- Tools Required: Socket set, wrenches, torque wrench.
- Torque Values: Refer to manufacturer specifications for specific torque settings during reassembly.

4. Check and Replace CV Joints

Inspect the CV boot for tears or leaks.
If damaged, remove the axle nut and disconnect the axle from the wheel hub.
Replace the CV joint or axle assembly as necessary.
- Tools Required: CV joint puller, socket set.
- Safety Warning: Ensure the vehicle is securely lifted and supported before working underneath.

5. Inspect and Replace Wheel Bearings

Remove the wheel hub to access the wheel bearings.
Check for excessive play; if present, replace the bearings.
Reassemble the hub and ensure proper torque on all nuts and bolts.
- Tools Required: Bearing puller, torque wrench.
- Safety Warning: Ensure all components are properly lubricated during reassembly.
