Cant remove the rotor and retainer clip

You will need a large bearing retaining nut socket (1-in drive) about 2 7/16th in or 61/62mm (I got mine at NAPA with a 1/2 in to 1-in drive converter) BUT BEFORE loosening the nut there is a small keeper under the bottom edge the nut at the top (12-oclock) position of the nut. Use a magnet to retrac this and then loosen the large bearing nut. You sometimes have to slightly move the nut "a hair" left or right to remove this bearing keeper. Once the keeper is out the nut will easily come off. The rest is easy. Good Luck!
