5. Disconnect the lower control arm from the steering knuckle.
6. Remove the CV joint from the transmission side.
7. Install the new CV joint in reverse order, ensuring proper torque specifications (typically 30-50 lb-ft for axle nuts).

3. Adjust or Replace Suspension Components

Sub-steps:
1. Check all suspension bushings for wear; replace any that are cracked or deteriorated.
2. Inspect the struts/shocks for leaks or damage.
3. If necessary, replace struts/shocks by removing the top strut mount, disconnecting the lower strut bolts, and reinstalling the new units.
4. Torque all bolts to the manufacturer's specifications.

4. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the wheel hub assembly by taking off the brake caliper and rotor.
2. Inspect the wheel bearing for noise and play; replace if necessary.
3. Install a new wheel bearing, ensuring correct alignment and fit.
