You need to remove the nut which is the hardest part of the job and then when you retorque it. But go read up on iy there is a running torque value you need prior to removing so you don't upset the pin ion bearing and either reinstall with too little or too much torque.
So without an air gun and compressor take it to a shop nit really expensive.
