It has a 1/2" rod from the scap box at work for an axle I used those wheels because they were laying in the garage they are lawnmower wheels no bearings I would use something different if I planned on pulling it on the open road. I built it for running to the store in town I may shorten the tongue when I get my german three speed back together and see how short I can get by with I hauled around #80 four blocks with it with no problem I spent about $8 on parts for it 2 u-bolts ,1 eye-bolt, 10 eye screws everything else I had or scrounged
