If low, add the appropriate power steering fluid as specified in the owner's manual.

3. Inspect and Replace Worn Components

A. Steering Components

Tools Required: Socket set, torque wrench
Remove the wheel and tire on the affected side.
Inspect tie rods and ball joints for play. If worn, replace as follows:
- Remove any cotter pins and loosen the nut on the tie rod end or ball joint.
- Use a ball joint separator tool to detach them.
- Install the new component and torque to manufacturer's specifications.

B. CV Joint Inspection

Inspect the CV joints for cracks or tears in the boots.
If damaged, follow these steps to replace:
- Remove the axle nut and any retaining clips.
- Pull the axle out of the hub and transmission.
- Install the new CV joint and axle, ensuring proper seating, and replace the axle nut with the specified torque.

4. Suspension Component Replacement (if needed)

Inspect struts and shocks for leaks and physical damage.
If replacement is necessary:
- Remove the strut assembly from the vehicle.
- Replace strut mounts if worn.
- Reinstall the strut assembly and torque bolts to specification.
