During the test, we wanted to use a T-type copper pusher, the T-type was installed as shown in the picture, which would cause the T-type copper pusher and the steering knuckle to fit too tightly. A T-type copper bushing is used between the C-HUB and the steering knuckle. This is the correct way to use the T-type copper bushing, but the steering knuckle needs to be changed to a slotted one, which will cause new problems. If the user chooses to use the original stepped screw, the steering knuckle will first rub against the C-hub with a large slot, which will cause great damage. So we use a straight copper pusher instead. When installing, you don't need to use a lot of force to tighten the screw, because the nylon C-hub will clamp the screw, so you don't need to tighten it too much, and the screw will not fall out. Package List: 2 × Brass steering knuckles, 4 × M3*10mm Screws.
