Grease in the gears stock works very well for the common enthusiast. Some even run it racing. I had to go so far as to release the grease that comes in the diffs because so many asked for it.
THE CAR DOSE NOT COME WITH HD LIGHTED OUTDRIVES... so your selling a car with parts designed to fail so you can make money selling updated parts...
ive measure the STOCK parts... they where made for the viscosity of grease... not diff oil... i changed them to a tighter tolerance .03mm fit for gear oil... works fine for the ID... then just made the a size for size tap fit into the diff case for OD... = no leaking
ALSO adding a second bearing to the front and rear outdrives.. dramaticly reduced the leaking... there only flogging out due to vibration caused by large tolerances in the outdrives and no support... dual bearings on every outdrive would solve this problem.... im currently redesigning the diff housing to accommodate dual bearings on the out drives
