I usually will put the other nut on very tight to help with leverage since you have it broken free already. It should help with the leverage. Don't use just any oil either. You need a deep penetrating oil such as Aerokroil or LPS - KB-88 http://www1.mscdirect.com/CGI/GSDRVS...00000087638049 This stuff is very impressive and works in seconds. Aerokroil is good but takes some time.
