Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: floor jack, jack stands, socket set, torque wrench, pry bar, grease gun (if re-greasing is applicable).
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Remove Wheel

Loosen the lug nuts on the front wheel using a socket wrench.
Lift the vehicle with a floor jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Old Ball Joint

If necessary, remove the brake caliper and rotor for easier access (secure caliper with a bungee cord to avoid strain on the brake line).
Remove the cotter pin and castle nut securing the ball joint to the control arm using a socket.
Use a ball joint separator tool to detach the ball joint from the control arm.
Remove the ball joint from the steering knuckle, if applicable.

4. Install New Ball Joint

Position the new ball joint into the control arm and align it with the mounting holes.
Secure with the castle nut and tighten to the manufacturer’s specifications (typically around 50-60 ft-lbs, but check service manual).
Insert a new cotter pin to secure the castle nut.

5. Reassemble Components

Reinstall the brake rotor and caliper if removed.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (typically 80-100 ft-lbs).

6. Final Inspection

Recheck all bolts and components to ensure everything is properly secured.
Re-grease the new ball joint if it is not pre-greased.
