Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Check and Replenish Power Steering Fluid

Locate the power steering reservoir.
Wipe the dipstick clean, reinsert it, and check the fluid level.
If low, add the recommended power steering fluid (refer to owner’s manual for specifications).

3. Inspect and Replace CV Joints (if necessary)

Lift the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels using a socket set.
Inspect the CV joint boots for tears or grease leaking.
If damaged, remove the CV axle:
1. Remove the retaining clips and bolts securing the axle to the transmission and wheel hub.
2. Replace with a new CV axle (ensure it matches OEM specifications).
3. Reinstall and secure the axle with the retaining clips and bolts.

4. Inspect and Replace Wheel Bearings (if necessary)

While the wheels are off, grasp the wheel hub and check for play.
If there is excessive play, remove the wheel bearing:
1. Remove the brake caliper and rotor.
2. Use a bearing puller to remove the hub assembly.
3. Install the new wheel bearing (make sure to torque to manufacturer specifications).
4. Reassemble the brake components and wheels.

5. Examine and Replace Suspension Components (if necessary)

Inspect struts and control arms for signs of wear or damage.
If damaged, remove the strut assembly:
1. Remove the lower strut bolts and disconnect the sway bar link.
2. Detach the strut from the top mount inside the engine bay.
3. Replace with a new strut assembly and torque to the recommended specifications.
4. Reattach all components securely.
