Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Suspension Components

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel to gain access to the suspension components.
- Inspect the control arms, bushings, and ball joints for wear or damage.
- If any components are damaged, replace them with OEM or high-quality aftermarket parts.
- Reassemble the suspension and torque all bolts to the manufacturer’s specifications.

3. Inspect and Replace CV Joints

Sub-steps:
- Check the CV joint boots for tears or leaks; if damaged, replace the boot and repack with grease.
- If the CV joint itself is damaged, remove the axle from the hub and replace the joint or the entire axle assembly as needed.
- Reinstall the axle and ensure proper torque settings are applied to the axle nut.

4. Check Power Steering System

Sub-steps:
- Inspect the power steering fluid reservoir; top up or replace fluid if low or dirty.
- Look for leaks in the power steering lines and rack and pinion assembly.
- If leaks are found, replace the affected components.

5. Inspect Wheel Bearings

Sub-steps:
- With the vehicle lifted, grab the wheel at 12 and 6 o'clock positions and check for any play.
- If play is detected, the wheel bearing should be replaced. Remove the hub assembly and replace the bearing using a bearing press.
