On mine I just did both rears within the last few weeks. I dropped the wheel pulled the cap, put it back on. I then soaked the axle nut liberally in WD-40 and let it sit. I purchased a Milwaukee hammer gun but it didn’t have the grunt to loosen the axle nut which yes is 36mm. I used my breaker bar with a galvanized pipe over that with a 36mm axle nut socket to break and loosen the axle nut. Takes a lot of back work to make it happen. There are four 18mm bolts on the backside holding the hub in place, also hit those with WD-40. They weren’t that bad. The hard part is after all the fasteners are out time to pull the hub. I went to my dads because he has an oxygen acetylene torch set up and we heated it and pried the hub straight out. Replacement is reverse.
