Entire underbody is power washed and completely sealed with automotive rust preventative undercoating. All mechanical and electrical components removed in disassembly are carefully inspected, tested and either repaired or replaced. Some, but not all, new components include; misc. steering, brakes, axle, shifter and suspension components as well as throttle, clutch, heater, and brake cables. So much more work goes into the important mechanics of our buses there is too much to list, but feel free to ask any questions.
