This rig has been through a lot, it has conquered some of the roughest terrain and is still going strong. I have gone through the whole vehicle. I completely disassembled it, washed everything thoroughly, and reassembled with new bearings, new gears in the transmission and transfer case, everything has fresh new grease. All new electronics. New stickers. I made some guards for the differentials to protect them from further wear because the plastic was starting to wear. You might want to replace the driveshafts in the near future as they are a little worn and have some play. All n all, it’s working as it should. All you need is a battery and charger.
