Solution

1. Preparation

Gather tools and safety gear before starting.
Tools Required: Socket set, torque wrench, jack stands, pry bar, and a multimeter.
Ensure the vehicle is on a level surface and the engine is off.

2. Inspect and Replace Worn Suspension Components

Sub-steps:
- Use a socket set to remove the wheels for easier access to the suspension.
- Visually inspect control arms, bushings, and struts for signs of wear or damage.
- If any component is worn, proceed to replace it with OEM parts.
- Reinstall the wheels and torque lug nuts to manufacturer specifications (typically around 80-100 ft-lbs depending on the model).

3. Inspect CV Joints

Sub-steps:
- Check the outer and inner CV joints for any signs of torn boots or grease leakage.
- If damaged, remove the axle by loosening the transmission mount and the wheel hub assembly.
- Replace the CV axle with a new one and ensure to use new CV joint grease.
- Reassemble the axle and torque all fasteners to the specified values.

4. Check and Replace Wheel Bearings (if necessary)

Sub-steps:
- Using a pry bar, check for play in the wheel bearings by moving the wheel side-to-side.
- If there is excessive play, remove the hub assembly to access the bearings.
- Replace with new wheel bearings, ensuring proper alignment and lubrication.
- Torque the hub assembly to the manufacturer's specifications.

5. Inspect Steering Rack and Linkages

Sub-steps:
- Inspect the steering rack for leaks and ensure all mounting points are secure.
- Check the tie rod ends and linkages for any signs of wear or looseness.
- Replace any worn components and ensure all connections are tight.
- Reassemble and check the steering alignment if adjustments were made.
