Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap, wipe the dipstick clean, and check the fluid level.
If low, add the recommended power steering fluid until it reaches the proper level.

3. Inspect and Replace CV Joints (if necessary)

Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheels using a lug wrench.
Inspect the CV joint boots for tears or leaks. If damaged, proceed to replace:
- Remove the axle nut with a socket and breaker bar.
- Detach the lower control arm from the knuckle.
- Slide the CV axle out of the transmission and replace it with a new unit.
- Reassemble all components and torque to manufacturer specifications.

4. Inspect and Replace Suspension Components (if necessary)

Check the struts and coil springs for any signs of damage or leaks.
If worn, replace the struts:
- Remove the strut assembly by unbolting it from the upper mount and lower control arm.
- Replace the strut and reassemble, ensuring all bolts are torqued to spec.

5. Inspect and Repair Steering Components (if necessary)

Examine the steering rack for leaks. If leaking:
- Remove the steering column covers.
- Disconnect the steering column from the rack.
- Unbolt the steering rack and replace it with a new unit.
- Reconnect and ensure proper alignment.
