Wheel bearing i have didnt come with bolts
It connects the wheel bearing hub assembly to the knuckle, there is 3 on the back side of the hub. All I can find online is the part number, no specs. Thinking I might have some of these at my uncle's just easier to have the sizing instead of breaking one and not having it.

 

Go into a hardware store with a hub and check fit. Believe you re-use the old bolt usually. Want to say it's a 12 or 14mm course thread flange bolt, grade 10.8
