Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely lift the front end using jack stands.
Disconnect the battery to prevent any electrical issues while working.

2. Inspect and Replace CV Joints

Inspect CV Joints:
- Remove the wheel on the affected side using a socket set.
- Visually inspect the CV joint boots for tears or leaks.
- Rotate the joint while observing for any unusual play or noise.
Replace CV Joints (if necessary):
- Remove the axle nut using a socket wrench.
- Separate the CV joint from the hub assembly using a puller if necessary.
- Install the new CV joint by reversing the removal steps, ensuring proper torque specifications are followed (usually around 30-50 ft-lbs for the axle nut).

3. Check and Replace Suspension Bushings

Inspection:
- Check all bushings for cracks or excessive wear.
Replacement:
- Remove bolts holding the control arm using a socket set.
- Press out the old bushings using a bushing removal tool.
- Press in new bushings and reassemble the control arm, ensuring to torque bolts to manufacturer specifications.

4. Tighten or Replace Loose Components

Inspect all bolts and fasteners on the suspension and steering components.
Tighten any loose bolts to the manufacturer’s torque specifications.
If any components are damaged or worn, replace them accordingly.
