I just finished posting about your trailer.<br /><br />Put some penatrating oil on the nuts and studs leave overnight and take a T bar (or inpact wrench if you have one) and break the rusted seal.<br /><br />An impact wrench would work best because the vibration of the wrench will break right through that rust. Take it to a gas station and ask them to back them off unless you have a buddy with an air wrench.<br /><br />I would replace the studs and nuts its not hard. Trailer wheels are nothing to take chances with. I had a wheel come off a pop-up camper and it's no fun. It happened even though I played by all the rules, If you can't do it yourself it's not expensive to have done. <br /><br />Whoever puts the nuts back on make sure they use a torque wrench and tighten to 95 foot pounds.<br /><br />Lug nuts are extremely important to check frequently if you don't have a torque wrench buy one. You will need it for many motor repaires anyway.<br /><br />Good luck
