Wheel bearing bolt size needed

[Placemotorsports]

What size bolts hold the wheel bearing/hub assembly on? I'm talking about the 4 bolts that are sandwiched inbetween the hub and the bearing.

17mm

I mean the actual size of the bolt not just the head size

I see i think they are M10x1 or 1.5

Thanks Slow, do they have to be grade 8 or will stainless ones work?

Don't use stainless- too soft.

Any idea how long they should be?

If you are replacing the entire hub assembly it will come with new bolts. Once assembled, the hub bolts can't be removed without pressing the hub apart...

I don't know the exact length though...

I bought the bearing and a hub and I'm going to press them together here ar work so i can swap it out tonight. Just need to make sure i have long enough bolts before i press it together

What happened to the old bolts? Did you break it- carnage pics!

No it's still on the car she is driving. Trying to make this side easier than the other side that I did last week. It was hell getting the old bearing off the hub.

I just measured my old bolts (I save stuff like that...)

You need 34mm of thread past the bolt head.

Important to note that there is a 2mm thick washer under the bolt head, so effectively 32mm of available thread.

Awesome, thanks Antman!
