hey just a general ? I bought my buggy used here on rctech and I think the guy ran it for one season and I put another 2 seasons on it with virtually no preventive maintenance, only things I did was replace parts that broke , hinge pins, shock shafts and such. well now im in process of going over it, so far ive changed diff fluids/gaskets/bearings and most of the bearings im coming across in the process, shock fluids, bent hinge pins, worn out cv/dog bones, couplers. anything else im missing? I didn't get to build it from new so this is my first e buggy so im kinda new to all this 4 wheel drive stuff. I mainly run stadium
