Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Suspension Components

Inspect Suspension:
- Use a jack and jack stands to lift the vehicle safely.
- Visually inspect the control arms, ball joints, and tie rod ends for wear or damage.
Replace Worn Components:
- If any component is found damaged, remove the affected part using a socket set.
- Install the new part, ensuring it is torqued to the manufacturer’s specifications (consult repair manual for specific torque values).

3. Power Steering Fluid Check and Replacement

Check Fluid Level:
- Locate the power steering reservoir and check the fluid level.
Replace Fluid if Necessary:
- If the fluid is low, top it off with the recommended power steering fluid.
- If the fluid is dirty or contaminated, drain the system using a siphon, then refill with new fluid.

4. Wheel Bearing Inspection and Replacement

Check Wheel Bearings:
- Spin the front wheels by hand to ensure smooth rotation without noise.
Replace Bearings if Faulty:
- Remove the wheel and brake caliper using a socket set.
- Take off the hub assembly to access the bearings.
- Replace the bearings with new ones, ensuring they are properly lubricated.
