The front hub puller (3-3/4 to 4-1/2in), rear axle puller (4-1/2 to 5-1/2in). The pullers fit snugly on the front wheel and rear axle hubs, working together with the tapered forcing bolt to provide straight and even force so your front and rear axles pop out cleanly, leaving the wheel bearing inside the joint and the rest of your vehicle untouched.
