Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if necessary for electrical component work.

2. Inspect and Replace Suspension Components

Lift the Vehicle
- Use a hydraulic jack to raise the front of the vehicle and secure with jack stands.
Check Ball Joints and Control Arms
- Visually inspect ball joints for any play or abnormal wear.
- If damaged, remove the control arm assembly by:
  - Removing the retaining bolts using a socket set.
  - Detaching the ball joint from the steering knuckle with a ball joint separator.
  - Installing the new control arm in reverse order, ensuring to torque bolts to manufacturer specifications (typically 50-70 ft-lbs).
Examine CV Joints
- Inspect the CV boots for tears or leaks. If damaged:
  - Remove the axle nut with a socket and breaker bar.
  - Disconnect the CV joint from the hub by tapping with a hammer if necessary.
  - Replace the entire CV axle if the joint is damaged. Ensure proper installation and torque the axle nut to the specified value (usually around 150 ft-lbs).
Check Wheel Bearings
- Spin the wheel to check for roughness or noise.
- If bearings are defective, remove the wheel and brake assembly.
- Replace the wheel bearing using a bearing puller and press to install the new bearing.
Reassemble Components
- Reattach all components in reverse order, ensuring all bolts are torqued to specifications.
- Reinstall the wheel and lower the vehicle.
