Leak is always a priority, in order to prevent more involved repairs. Hard to tell from that picture but it looks like your wheel well opening is above the steel rim of the tire. That would indicate a good axle
at least on mine. Axle
even if bad as the totally shot one in our before picture will generally allow short trips to local campgrounds that don't involve bad roads. We used ours for trips close to home for a couple of seasons before replacing the axle
I see you have what looks like an awning
track and you also have the old style "three tree" decals in the original locations, as well as what I think is the original stripe off of the letter "S" of scamp
. Later models they have a space between long stripe and letter "S"
Side views of our trailer showing with both good and bad axle. When viewed from the side how high up into the wheel well opening the tire sits and how low the trailer is are good quick visual indicator. Not a replacement for more in depth assessment but a pretty good indicator.
Before replacement: Note the wheel opening top is across the wheel not the tire.
After new axle restoring original height. Note the wheel opening is above the wheel and across the rubber of the tire.
