6. Reinstall the wheel and lower the vehicle back to the ground.

3. Inspect and Replace Suspension Bushings

Sub-steps:
1. Identify and remove the affected suspension components (control arms, sway bar links).
2. Remove old bushings using a bushing removal tool if necessary.
3. Install new bushings, ensuring they are properly seated.
4. Reattach the components, tightening to manufacturer specifications.

4. Alignment Check

Sub-steps:
1. After replacing components, take the vehicle to a professional alignment shop.
