Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and securely lifted using a jack and jack stands.
Disconnect the battery before starting work on electrical components.

2. Inspect and Replace Suspension Components

Remove Wheel:
- Using a socket set, remove the lug nuts and take off the front wheel.
- Tools Required: Socket set, lug wrench.
Inspect Tie Rods and Ball Joints:
- Visually inspect for any signs of wear or damage.
- Grasp the tie rod and ball joint and try to move them; any play indicates they need replacement.
Replace Damaged Components:
- If any tie rod or ball joint is worn, remove the old component using a ball joint separator.
- Install the new component by aligning it properly and tightening to manufacturer torque specifications (typically around 50-60 ft-lbs for tie rods).
- Tools Required: Ball joint separator, torque wrench.

3. Inspect and Replace Sway Bar Links

Locate Sway Bar Links:
- Identify the sway bar links and inspect for damage or looseness.
Remove and Replace:
- Remove the sway bar link using a socket set.
- Install the new sway bar link and tighten to manufacturer specifications.
- Tools Required: Socket set.

4. Check Wheel Bearings

Inspect Wheel Bearings:
- With the wheel removed, check for excessive play in the hub assembly by moving the wheel in and out.
Replace if Necessary:
- If play is detected, remove the hub assembly and replace the bearings, following specific manufacturer procedures.
- Tools Required: Bearing puller, torque wrench.
