Solution

1. Preparation

Gather tools: socket set, torque wrench, jack and jack stands, OBD-II scanner, and safety goggles.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the manufacturer-recommended fluid if low.
If the fluid is discolored or contaminated, drain and replace it.
- Use a turkey baster to remove old fluid, then refill with new fluid.

3. Inspect CV Joints and Boots

Lift the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the CV joints for any signs of damage or leaks in the boots.
If any damage is found, proceed to remove and replace the affected CV joint or axle assembly:
- Remove the wheel and brake caliper for access.
- Unscrew the bolts securing the axle to the hub and transmission.
- Install the new CV joint or axle, ensuring proper torque specifications are followed (typically around 50-70 ft-lbs).

4. Examine Suspension Components

Inspect control arms, bushings, and struts for signs of wear or damage.
Replace any worn components:
- To replace control arms, remove the bolts securing them to the frame and knuckle.
- Install new control arms and torque bolts to manufacturer specifications.

5. Check Wheel Bearings

With the vehicle lifted, grasp the wheel at the top and bottom and attempt to rock it.
If there is play, the wheel bearing may need replacing:
- Remove the wheel and brake components, then remove the hub assembly.
- Replace the wheel bearing using a bearing press, ensuring it is seated properly.
