3. Replace Worn Bushings

Sub-steps:
- Identify and remove any suspension components that are secured with bushings that need replacing.
- Use a bushing removal tool to extract the old bushings.
- Clean the mounting area thoroughly before installing new bushings.
- Press or hammer the new bushings into place ensuring they are seated properly.
- Reassemble the suspension components and torque bolts as per manufacturer specifications.

4. Inspect and Adjust Wheel Bearings

Sub-steps:
- Remove the wheel and brake assembly to access the wheel hub.
- Check the wheel bearing for play by attempting to wiggle the hub.
- If there is excessive play, replace the wheel bearing as needed by removing the hub assembly and replacing it with a new unit.
