🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the front wheel

• Use a 21mm socket and breaker bar to loosen the lug nuts, then remove the wheel.
• Set the wheel aside where it will not roll away.

Step 2: Access the ball joint

• Spray penetrating oil on the ball joint nut and mounting bolts.

• Use needle-nose pliers or a cotter pin puller to remove the cotter pin from the ball joint stud.
• Use a 19mm socket to remove the castle nut.
• Leave the nut threaded on a few turns to keep the knuckle from dropping suddenly.

Step 4: Separate the ball joint from the steering knuckle

• Use a ball joint separator (specialty) to pop the taper loose.
• If needed, tap the knuckle lightly with a hammer while keeping pressure on the separator.
• Once it breaks free, remove the nut and support the knuckle so the brake hose is not strained.
