There are two 3/8" threaded holes on the front of the rotors. Get two 3/8 bolts about 1 1/2- 2" long and go back and forth driving them in. This will push the rotors right off.

I had the same problem with my 03 1500 z71. I had to take a gear puller to get mine off. They were just rusted and stuck on. There is nothing holding them on other than two little clips that go over two of the studs. Those are put on for use at the factory and can be easily broken off or cut with tin snips.

spray the backside, where the rotor meet the mate, and spray it with some PB careful not to get it on the rotors .....bang on the rotors a bit with a copper hammer to set up micro fractures in the rust for the oil to pass thru....then bang on them a bit more til they loosen up. I had some really bad ones myself....not fun

How to remove crossfire front brake rotors

front rotor removal you need to remove the brake caliper including the brake caliper bracket so nothing is in the way, there should be a 7mm set screw in the rotor remove that, then get some pb blaster and spray the center part of the hub and the back part of the hub very liberally then you have to use a hammer and beat it off, a way to make it easier is to rotate the rotor as you beat it. It will come off.

I'm trying to replace the rotors on 2001 Tundra. Calipers are off but rotors won't budge. medium pounding all the way around but they won't budge.

Thanks for choosing FixYa and welcome to the site. Rotors are hard to get off sometimes, especially without the right tool. If you are changing them anyway, go ahead and use a hammer to break off a piece. Once it is broke, it will come out a lot easier. If you are not breaking them, you really need a rotor tri pod tool. Spray PB blaster or some other chemical on it and keep trying to break it loose. There is nothing holding it on there, it is just snug.

Back brakes nut for holding rotors, size?

I'm assuming you want to remove the rear rotors. No rear brake rotor nut for holding the rotor on that I know off. I just had my rear rotors off and turned on my 94 Concorde LX.
After removing the tire I diligenty removed the star washers (2) from the lug studs. Then a little spray of PB Blaster around the center hub. Next I removed the 2 10mm bolts holding the caliper to the rotor. A slight nudge with a rubber mallet and the caliper is free, but do support it, don't let it dangle. Another slight nudge on the rotor with a rubber mallet and the rotor literally fell off the car.
There is a rear axle nut and bearing inside of the center hub that is secured by a large 34mm hex nut, on the outside of that a lock ring that looks like a large black bottle cap with a cotter pin going through it for retention. That has nothing to do with removing the rotors. With a little patience, lubricant and gentle tapping, the rotors slide off the center hub. Hope this helps.

How difficult is it to cange the front rotors?

depending if you have the tools to do the job and pb blaster lock tite and white and dark grease for a beginer it has a rating of 7-8. if you work on cars and know what your doing, then its easy.. first thing is to remove the calapers then remove the calaper mounting bracket spray around the studs and bolts with pb blaster also around the hub and tap around the whole area around rotor dont hit the studs (with hammer) to break the rust buildup this should break rotor free then you may want to clean the rust off so that the rotors seat properly remove and clean new rotors with brake cleaner to get off the film off them (shipping rust retardent) and wipe. spray bolt holes to clear any rust left while removing old rotor and braket and dry. place a small ring of lock tite on bolts holding caliper brackets and let stand till harden or almost hard. replace new rotors install bracket/s and bolts (torq to ? 80foot lb) while replacing rotors replace brake pads, replacing just rotors will over heat new rotors in spots and warp rotors!!! make sure you pull the pins that retain the calipers to the bracket and add light coat of white grease to pins so calipers slides easy and evenly

Can't get the damn rotor off 06 Hyundai Sonata

Depends somewhat if it's a front rotor or a rear rotor. The most common problem will be "corrosion" that's binding the two metal parts together. If you are not trying to reuse the rotor after turning (many are throwaways now adays) take a large hammer and bang the outer edge of the rotor. The vibration should cause the corrosion to break apart, and the rotor should pull away. If your planning on re-using the rotor after turning use a large rubber mallet.

The front rotors have about a 3/4 inch common surface between the rotor and the wheel hub. You may need to bang on the backside of the rotor as you slowly turn the rotor in order to cause the two parts to slide apart. It can be a slow process, but you should see some movement (but it must be even movement around the entire rotor. The back rotors have far less common surface and a few good waps should break the parts free.

Cant get seized rotor off 01' durango.? tried a hammer.? any ideas.?

You can try liquid wrench or PB Blaster sprayed on the hub and a bigger hammer. It will just take brute force to get it off. For future endeavors, put anti-seize compound on the hub before installing the rotors.
