Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts.
Wear safety gloves and goggles.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir.
2. Remove the cap and check the fluid level; top off with the recommended fluid if necessary.
3. If the fluid is dark or contaminated, drain and replace it with new fluid.

3. Replace Damaged CV Joints

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Remove the front wheels.
3. Inspect the CV joints and boots for tears or damage.
4. If damaged, remove the axle nut and disconnect the CV joint from the transmission.
5. Install the new CV joint, securing it with the axle nut to the manufacturer’s torque specifications (typically around 150-180 ft-lbs).

4. Replace Worn Suspension Components

Sub-steps:
1. Inspect control arms, bushings, and ball joints for wear.
2. Remove any damaged components by unbolting them from the frame and subframe.
3. Install new parts, tightening bolts to manufacturer specifications.
4. Reassemble any removed components.

5. Check and Replace Wheel Bearings

Sub-steps:
1. Remove the wheel hub assembly after removing the brake caliper and rotor.
2. Inspect the wheel bearing for play or noise.
3. Replace the wheel bearing if faulty, ensuring proper alignment during installation.
4. Reinstall the hub assembly and torque the bolts to manufacturer specifications.
