Cherokee hub question

[Jeep4230]

I have a jeep Cherokee I am working on and the u joints are bad. The can get everything apart down to the hub. But I am questioning what up with the bolts that hold the plate on out side of the outer knuckle. Are they some special bolts if so what s the type and size thanks

I'm pretty sure they are M 12 bolts, but hardened, 10.9 equal to a SAE 8. I remember using a regular socket, half inch drive to get them out, nothing exotic. Getting the hub off is a whole other can of worms. I buy three M12 x 100MM bolts, screw them in there and use a big hammer on the bolt heads, the hub is usually rusted on there pretty good. I occasionally switch positions (move to another bolt hole) and turn the wheel to another position to get a good swing.

Trying to use a puller, or to wedge or pry them off is usually (always) wasted effort.

Just a 12 point bolt instead of 6, nothing exotic.
