This past summer i replaced all my bearings and bushings(plan on doing the olite bushings in the bulkhead,stock has top much play).As for other things to check you may want to coat the wires that run under the toolbox in the front of the sled with plastic wire armor(wires chaf on the bulkhead and short out).Also check the condition of the vent line hose.Mine was leaking so i installed a new line.Also rebuilded the shocks in the front and back,made a world of difference in mine(except the rear shock in the warrior,had to do a custom job on mine because its not rebuildable).
