no case damage we were just trail riding so not pounding to bad.talked with a few drag racers the ones not using the chain drive kit for DD are using DD light.deff rebuildable planing on rebuilding and selling.if I were you I would prob replace 5 pinion gear with BDX pinion gear just for pice of mind.gear bearings and oil about 250.I figurd if I was goingb to rebuild stock drive to keep I would do all new gears bearings and a extra pinion gear for the tool box so being in the motor sports biz I assume your price would be around 200 for standerd rebuild parts just under 400 for full rebuild.and about 700 for light drive and shaft and reverse helix
