Solution

1. Preparation

Ensure the vehicle is parked on a level surface and engage the parking brake.
Gather necessary tools and parts.
Wear safety goggles and gloves for protection.

2. Inspect Suspension Components

Tools Required: Jack, jack stands, socket set, torque wrench
Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect control arms, bushings, and shocks for any signs of wear or damage.
Tighten any loose bolts to their specified torque values as per the manufacturer’s specifications.

3. Check CV Joints

Tools Required: Axle puller (if necessary)
Remove the wheel to access the CV joint.
Inspect the outer CV joint boot for cracks or tears and check for grease leakage.
If the joint is damaged, replace the CV axle. To do this:
- Remove the axle nut using a socket.
- Disconnect the lower control arm to facilitate removal of the axle.
- Install the new axle and torque the axle nut to the manufacturer's specification.

4. Examine Steering Linkage

Tools Required: Wrench set
Inspect tie rods for any movement or looseness. If they are damaged, replace them by:
- Marking the position of the tie rod on the steering rack for alignment.
- Remove the cotter pin and nut securing the tie rod end.
- Unscrew the tie rod from the steering rack.
- Install the new tie rod, aligning it to the marked position, and secure it with the nut and cotter pin.

5. Verify Wheel Bearings

Tools Required: Wheel bearing puller (if necessary)
Spin the wheel while it is off the ground and listen for noise.
If noise or play is detected, replace the wheel bearings by:
- Removing the brake caliper and rotor.
- Use a bearing puller to remove the old bearing.
- Install the new bearing and reassemble the brake components.
