Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery for safety if working on electrical components.

2. Check and Replace Power Steering Fluid

Locate the power steering reservoir and inspect fluid level.
If low, top off with the manufacturer-recommended fluid.
If the fluid appears dirty or contaminated, drain and replace it.

3. Inspect and Replace CV Joints

Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheels to gain access to the CV joints.
Inspect the CV boots for tears or leaks; replace any damaged components.
If the CV joint is worn, replace the entire axle assembly as follows:
- Remove the axle nut using a socket and breaker bar.
- Disconnect the lower control arm and remove the axle from the hub.
- Install the new axle by reversing the removal steps and torque the axle nut to manufacturer specifications.

4. Inspect and Replace Wheel Bearings

With the vehicle still lifted, check for play in the wheel bearings.
If grinding is present, remove the hub assembly:
- Remove brake caliper and rotor.
- Disconnect any ABS sensors if equipped.
- Remove the hub assembly using appropriate pullers.
Install new wheel bearings:
- Use a bearing press to install the new bearings into the hub.
- Reassemble the hub onto the vehicle and torque to specifications.

5. Inspect Suspension Components

Visually check struts, control arms, and bushings for wear or damage.
Replace any worn suspension parts as necessary:
- Remove the affected components and install new ones using manufacturer specifications for torque and alignment.
