I'am rebuilding my 26 rear axel and found a nice cleaning brush set at Home Depot. It comes with two brushes one about 3 inches in dia. with a flexable 36 Inch handle. The other is tapered about 30 Inch handle . It tapers from around 1 1/4 inches down. It is a GE set in the appliance department GE # PM14X10056. Set cost about $ 10.00 and worked fine on my cleaning chore.
