While coming home from Garner we passed a couple that had pulled off the road with their pop up.We turned around to see if they were ok to find that his bearings overheated on him.He had same type of trailer as mine and I had a old set still in my tool box .We got lucky and old bearings did'nt freeze on axle.We put other set in and checked other side to find they still had a little grease left.We greased them up and they got back on the road-Houston.They called later that night to let us know that they made it home.I know you can go along time before re-greasing thats why we install buddy bearing caps on our trailers ,a quick easy way to make sure you won't have problems.Stay safe and good trips to all.
