Hello, I have a 93 Honda Accord LX 2.2L that I am replacing the rotor on. There are 4 bolts that hold the hub and disc assembly to the steering knuckle. I have never seen bolts like this. And don't know how to begin searching for a tool to remove them since i don't know what they are called. The bolt looks like it would take a multi pointed socket of sorts, yet it very rounded looking. The points are very small and somewhat rounded, i am guessing there are somewhere between 12-16 points. Anyone know what this is called and what tool i can use to remove them?

Thanks

 

They are 12-point 10mm or 12mm bolt heads. If you can get the cv shaft removed partly or completely, it makes getting to them rather easy. Be careful not to round them off.

 

eta: with the cv shaft our of the way, you can use a ratchet with 12-point socket or the box end of a 12-point 10/12mm wrench.

 

Thanks Supernaut,
It looks to be a 10mm, had no idea they made sockets with that many points. I have the entire steering knuckle removed cause i am doing balljoints, springs/struts, tie rod ends, CV shaft so access is easy now!

 

Sweet! Good luck with everything.

 

Ok just got back to my Honda project and I am finding that I cannot separate the steering knuckle from the hub to get to the rotor. All bolts are removed. Do I have to have this thing pressed out? Figure i could just pop it off with a mallet, but no luck.

 

Yeah, they probably put salt on the roads in Dayton...
If you leave the car sitting in a museum for 18 years, it would probably come out pretty easily...

propane torch??
I never had one of those older Hondas with the hub outside the rotor, but I hear they're a pain.

 

The hub and bearing are the only two items pressed together. The bearing is bolted to the knuckle, and you have removed the bolts. In an ideal world, you now should be able to pull the hub/bearing out of the knuckle.

Now you will have to use some force to remove the hub/bearing from the knuckle.

The first hit is the YouTube video showing one way to do this.

 

Thanks everyone for the advice, I should be able to get it off now. The video was most excellent

 

If all else fails, thread the bolts about halfway into the hub, put a 12 point 10mm deep socket over the bolt(s) and hit it with a hammer at one corner, then the opposite....don't hit it so hard you annihilate it...but use enough force to break it loose. And use some pb blaster.
