It's not a really hard job, but if you don't have a press to take out the old races and press in the new ones it's a pain doing it with a hammer and punch. BEST option is to take it over to Odem Trailers in Conroe and let them do it. For a two wheeler it probably won't cost too much and they will do a pro job. Then you can go home and drink some beers knowing that a wheel isn't going to come off while you make the trip to Toledo..
