Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir.
2. Remove the cap and check the fluid level; if low, top off with the recommended power steering fluid.
3. If the fluid is dirty or contaminated, drain and replace it completely.
  - Use a turkey baster or fluid pump to remove old fluid.
  - Refill with fresh fluid and check for leaks.

3. Inspect and Replace CV Joints

Sub-steps:
1. Lift the front of the vehicle using a jack and support it securely with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the CV joints for any cracks or tears in the boots; replace if damaged.
  - To replace, remove the axle nut using a torque wrench.
  - Slide the new CV joint into place and secure it with the axle nut to manufacturer specifications (typically around 250 Nm).
  - Reinstall the wheel and lower the vehicle.

4. Replace Wheel Bearings (if necessary)

Sub-steps:
1. Remove the brake caliper and rotor to access the hub assembly.
2. Remove the wheel bearing retaining bolts and the old bearing.
3. Install the new bearing, ensuring it is pressed in correctly.
4. Reinstall the rotor and caliper, and torque bolts to specifications (typically around 100 Nm).

5. Inspect and Replace Suspension Components

Sub-steps:
1. Check control arms and bushings for wear.
2. If damaged, remove the bolts securing the control arm and replace it.
3. Torque new control arm bolts to manufacturer specifications (typically around 100 Nm).
