I'm going to replace the rotors on my 98 dually on the back of the hub assembly there is a strange bolt what size is that? and where can I buy a socket for it? I'm guessing it's metric. Any tips or advice on replacing the rotors would also be appreciated.

 

I crawled under there it's a twelve point. But I still need some good advice on the rotors and hub removal. Thanks for any advice on this.

 

The bolt is a 9/16 head 12 point.

 

Farmer,

12 point 14mm works too, atleast, on my 01 it did....

Its actuaally a 14mm 12 pt. Do a search on the rotor procedure.

 

9/16" is slightly bigger than 14mm. You stand the chance of rounding off the bolts using a 9/16" if they're rusted in there.
