Same here, are the 2500's different? Tractor supply has the axle nut socket fir $6.99, T handle breaker bar for $14.99, idk about other parts stores but all my local ones( napa,autozone,advance, and orieliys,) don't have them.

I know my 1500 you just remove the tire un do the two Allen bolts on the caliper and slide it off, the simply just pull off the rotor.

If your Calipers are not bad leave them alone, you'll have to bleed the air out of the brakes!
