Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack stands, pry bar.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery if necessary for safety.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Visually inspect the shocks and struts for leaks or damage. Use a pry bar to check for excessive play.
4. If damaged, remove the old shocks/struts using the socket set and replace with new components. Torque to manufacturer specifications (typically 40-60 ft-lbs).
5. Reinstall wheels and torque lug nuts to manufacturer specifications (usually 76-100 ft-lbs).

3. Check Steering Components

Sub-steps:
1. Inspect the tie rods and rack and pinion for any signs of damage or looseness.
2. If any components are worn, remove the tie rod ends using the socket set and replace them.
3. Align the steering components and ensure they are properly torqued.

4. Inspect Wheel Assembly

Sub-steps:
1. Check the wheel bearings for excessive play by shaking the wheel side to side.
2. If bearings are found to be faulty, remove the hub assembly and replace the bearings.
3. Reinstall the hub and ensure all components are tightly secured.
