Hi everybody,
Quick easy question, which direction of the grease seal faces the wheel bearing.

These guys have some great instructions but I can't tell which side of the seal is facing the bearing.

Attached are the images of my seals.

It's difficult to tell based on your pictures, but the "rule of thumb" that I always use is that the direction the lip is pointing goes toward the fluid you wish to contain.

The 1st image has an arrow pointing at the seam. So I guess is it seam side towards bearing or away.

The lip of the seal is the innermost part that rides on the shaft. A little bit difficult to judge from your pics, but I would install the side in the first pic towards the bearing. This will be orientated to better keep the grease inside the hub unit.

The axle housing has a seal on each side orientated to keep the oil inside the axle.

New Pic but I think it's rubber side towards the bearing, side with gap is up.
