Solution

1. Preparation

Ensure the vehicle is on a level surface and engage the parking brake.
Gather necessary tools and parts.
Wear safety gloves and goggles.

2. Check and Top Off Power Steering Fluid

Tools Required: Funnel
Locate the power steering reservoir and remove the cap.
Check the fluid level against the markings on the reservoir.
If low, add the appropriate power steering fluid as specified in the owner's manual.

3. Inspect and Replace CV Joints (if necessary)

Tools Required: Socket set, pry bar, CV joint boot clamps
Lift the front of the vehicle and secure it on jack stands.
Remove the wheel to access the CV joint.
Inspect the CV boot for tears and the joint for damage.
If damaged, remove the axle nut and disconnect the CV joint from the hub and transmission.
Install the new CV joint and secure it with the appropriate torque specifications.

4. Replace Wheel Bearings (if necessary)

Tools Required: Bearing puller, torque wrench, socket set
Remove the wheel and brake caliper.
Detach the rotor and hub assembly.
Use a bearing puller to remove the worn bearing from the hub.
Install the new bearing, ensuring it is properly seated and secured.

5. Inspect and Replace Suspension Components (if necessary)

Tools Required: Wrench set, torque wrench, ball joint separator
Examine each suspension component for wear.
If bushings or struts are worn, remove the old components by disconnecting them from the chassis and hub.
Install the new components according to the manufacturer's specifications, ensuring proper torque is applied.
