Hi Francisco, I'm glad to assist you. Part number WB513067 is a rear wheel bearing. The WBRP513067 is a rear axle repair bearing. The axle repair bearing and rear wheel bearing are different parts. Take note of the difference: 1. A regular wheel bearing is a component that allows the wheel hub to rotate smoothly and supports the weight of the vehicle. It is typically pressed into the wheel hub or knuckle assembly. 2. An axle repair bearing, on the other hand, is a component that allows the axle shaft to rotate smoothly and supports the weight of the vehicle. It is typically pressed onto the axle shaft and sits against the axle housing. Click the link below to order the correct part you need.
