Well which company are you talking about jelag? I'm still not sure how you seperate the rotor from the hub either. I read that the wheel studs get pressed out to get the rotor off and then press the studs back thru the hub and new rotor. Is that the way its done ?
I know when I did mine I removed the brake caliper and the rotor just slides off My truck is an 01 so I don't know if it is different.
