Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to avoid electrical shorts during inspection.

2. Tire Inspection

Remove the front wheels using a socket set.
Inspect the tires for uneven wear or damage; replace if necessary.
Clean any debris from the tire tread.

3. Steering Components Check

Inspect the steering rack and pinion for any signs of leakage or damage.
Tighten any loose bolts on the steering assembly to manufacturer specifications.
If the power steering fluid is low or contaminated, replace it with OEM fluid.

4. Suspension Component Replacement

Identify any worn or damaged bushings, control arms, or struts.
Remove any components that need replacement using appropriate tools (e.g., socket set, torque wrench).
Install new bushings or control arms, ensuring they are torqued to proper specifications.

5. Wheel Bearing and Axle Inspection

With the vehicle lifted, check for play in the wheel bearings by rocking the wheel back and forth.
If play is detected, replace the wheel bearings using a bearing puller and install new bearings and seals.
Reassemble and torque all components to manufacturer specifications.
