Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace CV Joints

Raise Vehicle: Use a jack to lift the front of the vehicle and secure with jack stands.
Remove Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Inspect CV Joint: Check the CV joint for any damage or torn boots. If damaged:
- Remove CV Axle: Disconnect the axle from the hub and transmission, noting any retaining clips.
- Replace with New Axle: Install the new CV axle, ensuring proper seating and reattach all fasteners to the manufacturer’s torque specifications (typically around 40-60 ft-lbs).
Reinstall Wheel: Place the wheel back on and hand-tighten the lug nuts.

3. Inspect and Replace Suspension Components

Check Control Arms: Examine control arms for bent or damaged components.
- Replace if Necessary: Remove the mounting bolts and replace with new control arms, tightening to specified torque values (typically around 75-90 ft-lbs).
Inspect Bushings: Look for worn bushings in the control arms and sway bar.
- Replace Worn Bushings: Remove old bushings and press in new ones, ensuring proper alignment.

4. Check Power Steering System

Inspect Fluid: Remove the power steering reservoir cap and check fluid level.
- Top Off if Low: Use the recommended power steering fluid (typically ATF or specific PS fluid) to refill.
Look for Leaks: Inspect hoses and connections for any signs of fluid leakage.
