Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, jack stands, pry bar.
Jack up the front of the vehicle and secure it on jack stands.
Remove the front wheels to access the suspension.
Inspect control arms and bushings for cracks or excessive wear.
If damaged, remove the old control arm:
- Use a socket to remove the bolts securing the control arm to the chassis and the steering knuckle.
- Replace with a new control arm, ensuring all bolts are torqued to manufacturer specifications (typically around 40-50 lb-ft).

3. Inspect and Replace CV Joints

Tools Required: CV joint puller, grease, torque wrench.
Inspect the CV joint boots for tears or leaks. If the boots are damaged, the CV joint may need to be replaced.
Remove the axle nut using a socket.
Use a CV joint puller to detach the axle from the hub.
Replace the CV joint as necessary, applying grease according to specifications.
Reinstall the axle and tighten the axle nut to the recommended torque (typically around 100 lb-ft).

4. Check and Replace Wheel Bearings (if needed)

Tools Required: Bearing puller, torque wrench.
With the wheel removed, check for play in the wheel bearing by grasping the wheel at 12 and 6 o'clock and shaking it.
If play is detected, remove the wheel bearing:
- Use a bearing puller to extract the bearing from the hub assembly.
- Install a new bearing, ensuring it is seated correctly and torque it to specifications.
