yes, remove the grease in the bearings. i just bought some oil from a skateboard shop. its a thin synthetic oil. one drop and it works great. i just tried this so i dont know how it will work over time yet. also remove the inner shields of the bearings. the two wheel bearings on each axle and the inner diff shields and the pinion bearings. also yokomo sells ceramic bearings and i dont think you need oil for these.
Yeah might get some of those one day.
I just tested one of the diffs by holding onto one of the outdrives (while diff was vertical) and spinning it on the bearing....
Very lightly oiled and spinning as hard as I could = 6 seconds.
Same method but dry bearing I got 30 seconds no problem at all.
