Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery for safety.

2. Inspect and Replace CV Joints

Tools Required: Jack stands, socket set, torque wrench, CV joint puller, grease.
Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Remove the front wheel to access the CV joint.
3. Inspect the CV joint for any visible damage or excessive play.
4. If damaged, remove the axle nut and detach the CV joint from the hub.
5. Replace with a new CV joint or entire axle assembly as necessary.
6. Reassemble the wheel and torque the axle nut to the manufacturer’s specifications.

3. Check and Replace Power Steering Fluid

Tools Required: Funnel, clean container for old fluid.
Sub-steps:
1. Locate the power steering reservoir and remove the cap.
2. Check the fluid level and condition; if dark or contaminated, proceed to replace.
3. Siphon out the old fluid using a turkey baster or similar tool.
4. Refill with the appropriate power steering fluid as specified in the owner’s manual.

4. Inspect and Replace Wheel Bearings

Tools Required: Bearing puller, socket set, torque wrench.
Sub-steps:
1. Remove the wheel and brake assembly to access the wheel bearing.
2. Check for play by wiggling the wheel; if movement is felt, the bearing may need replacement.
3. Remove the old wheel bearing using a bearing puller.
4. Install the new bearing and reassemble components, ensuring proper torque specs are followed.
