i have a new trailer...karavan i believe..when i picked it up the guy told me to add grease just untill i saw the plate the grease fitting is on move, then stop. well i checked them the other day..one took about 3 pumps....the other side had a lot of grease around the grease fitting...as if it leaked out...it took about 5 pumps untill i saw it move....does this mean a seal is broken..i hope this is understandable!!!
