How to replace a broken caravan leaf spring

Our dual-axle 2010 Jayco Expanda Outback uses a rocker suspension system (not a rocker-roller), and the rear springs can be susceptible to breaking when they get a hard impact, as we found out the hard way 3/4 of the way up Cape York Peninsula in 2020! Since then we always carry a spare set of springs, which is worth doing if you're doing full-time travel. Changing in a new set is actually an easy job to do provided you have a few basic tools, and only takes about an hour once you know what you're doing (though allow a few hours if it's your first time). Tools you'll require for my setup, yours may vary: 2x jacks 24mm long socket (to undo all the leaf spring nuts) Ratchet 19mm and 24mm open-ended spanners (to hold a couple of bolt heads if needed) Some WD-40 or similar (to help nuts come off more readily) A cordless drill / impact driver to help save a bit of time
