Find a round toilet bowl brush with a straight handle with a hole in the end, bend a 3’ish long piece of all thread around the handle and duck tape the all thread to the handle, chuck the other end in your cordless drill. I usually have a bucket of degreaser next to the axle I dip the brush into. Dip your brush, stuff it in the tube, turn your drill on and run that in an out of you axle tubes. Works great,makes a mess but works great
