Solution

1. Preparation

Gather tools and parts needed for repairs.
Park the vehicle on a level surface and engage the parking brake.
Raise the front of the vehicle using a jack and secure it on jack stands.

2. Inspect and Replace CV Joints

Inspect the CV joints:
- Check for cracks or tears in the CV boot.
- Look for any grease leaking from the CV joint.
Replace if needed:
1. Remove the wheel using a socket set.
2. Detach the axle nut with a socket wrench.
3. Disconnect the lower control arm from the steering knuckle.
4. Pull the CV axle out of the transmission or differential.
5. Install the new CV joint by reversing the removal steps.

3. Inspect and Replace Suspension Components

Inspect the control arms and bushings:
- Check for cracks, excessive play, or wear.
Replace if necessary:
1. Remove the bolts securing the control arm to the chassis and subframe.
2. Detach the control arm from the steering knuckle.
3. Install new control arm and bushings, tightening bolts to manufacturer specifications (generally around 50-70 ft-lbs).

4. Inspect and Tighten Steering Components

Check the tie rods and steering gear:
- Look for any looseness or damage.
Tighten or replace components as necessary:
1. Use a wrench to check and tighten tie rod ends to the specified torque.
2. If damaged, remove the tie rod ends and install new parts.
