anyone no the front wheel bearing nut size? also what size bolt fits the brake rotor?

[petermiddleton]

try to pop off a rusted on front disc brake rotor, there are two threaded hole in the rotor can bolts be threaded in there to put pressure between the rotor and hub? if so anyone know the bolt size and should I get a higher bolt grade

what size is the hub reataining nut?

I forget what size the rotor holes are.. I have a nice box full of random metric bolts.. just dug through it until I found one =/ If you can't find the right bolt size, just spray the hub area of the rotor with lubricant or something like brake cleaner.. and smack it with a hammer. A lot. It'll come loose eventually

The axle nut is 30mm, however. You will need a deep socket to remove it. Shallow 30mm will not clear the stub end.

The rotor removal holes should be 6 or 8 MM. Standard grade 5 from Lowes or Home Depot work fine. Use penetrating fluid. Not sure what conor meant by deep 30mm (yes I know what deep socket is) but usually sockets of that size are pretty deep anyway. I just used a standard 30mm. I would recommend 6 point not 12 point as the nut is fairly shallow and a 12 point will round the the flats more easily.

The screw size is an M8. I believe the thread pitch is 1.25, but I am not absolutely certain of that. I use socket cap screws for this application since they are made of a very strong alloy. I just toss them in my metric thread assortment and they are easy to find for the next brake job, since they are the only socket cap screws in there.

you are right on both M8 1.25 I just bought them
Pepboys has the 30mm axle socket for 12.99

I am wondering about just replacing rather than repacking the bearings camry wagon tow hitch often pulling trailer 221,000 miles on it

I believe your car has non-servicable wheel bearings. You have to replace the whole assembly. If they are ok, I would just leave them alone.
