I have to go get an old boat I picked up off the site tomorrow. Long story short the dealer needs it gone and the weather is turning to Saturday night. Trailer has been setting two years. I plan on pumping the grease to the hubs before I move it but is there anything else I can do or should do before a 80 mile trip home? How hard is it to replace hubs on a EZ roller trailer?Thanks in advance<br />Lee
