Once the screws are out the rotor will come off. If it doesn't come off easily there's a good way to free them. There is a threaded hole in the hub of the rotor. In the same area as the studs and the screws that hold it to the wheel hub. Find a bolt that threads in to that hole. Run the bolt in that hole and it will work like a press to push the rotor off the hub.




thats the easiest way. its more fun to hit it with a hammer though

sometimes the rotors are a bitch to remove, LIGHTLY tap them with a hammer to get em loose.




yep, forgot to mention that, mine felt practicly like they were welded on almost, lol, so i tapped em with a hammer and they came right off... my tap was quite a lot harder then your's will need to be though, i was replacein em so i didnt care about em

Yeah the screw thing works too, but it isnt nearly as much fun!

If i know im going to throw away the rotors, I get a good windup and haul-off on the rotor with the biggest hammer i got. It usually breaks loose and you get the whole "Chinese Gong" effect. Its fun.

i'm turning the rear rotors while it's in gear and notice that the drive shaft doesn't even move. recap: car is up on jacks, tires off, calipers off, rotors off, in gear, turn rear axles, driveshaft no go. comments?


Does the other side spin the opposite direction when you spin one side? If so, that's just the open differential doing its thing. Hold one side still, turn the other side, and you should see the driveshaft turn. Would be easier to do in neutral.
