No, the ones on the output flange. I have the 1 1/2 deep well socket but it's 1/2" and I'll be giving that try first.

If they are factory, it takes a 7/16" 12 pt socket for those. Torque is quite high (75 ft-lbs), I think 65 ft-lbs will do it with blue locktite.
If they have been changed to the ones McMaster Carr sells, they will be 3/8" 12 pt.

Be aware of the bolt lengths. You want the bolt to go all the way through the flange for maximum thread contact.
BUT if you have a One-Ton front end, the axle flange on one side is thinner than the other side (or maybe both flanges are thinner than OEM.. I don't
recall). This allows the bolt to extend through and it will hit the final drive casing. So those with the One-Ton must ensure the bolt shank does
not extend through beyond the flange and check for clearances. I believe this affects the drivers side.

My Staff says I never listen to them, or something like that
