Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lift it using jack stands.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Steering Components

Inspect Power Steering Fluid:
- Check the fluid level; if low, refill with OEM-spec power steering fluid.
Replace Damaged Tie Rod Ends:
- Remove the wheel to access the tie rods.
- Use a tie rod puller to detach the tie rod end from the steering knuckle.
- Install the new tie rod end, ensuring it is torqued to manufacturer specifications.

3. Wheel Bearing Replacement

Remove Wheel and Brake Assembly:
- Detach the wheel and remove the brake caliper and rotor.
Remove Old Wheel Bearing:
- Use a bearing puller to extract the old wheel bearing from the hub.
- Clean the hub surface thoroughly.
Install New Wheel Bearing:
- Press the new wheel bearing into place, ensuring it is seated properly.
- Reassemble the brake components and wheel, torquing to specifications.

4. Inspect and Replace Suspension Components

Check Control Arms and Bushings:
- Inspect control arms for cracks or excessive wear.
- Replace any worn bushings with new OEM parts.

5. Reassembly and Final Inspection

Reattach the negative battery terminal.
Lower the vehicle and perform a visual inspection to ensure all components are securely fastened.
