just built my tc6.1, and i got some questions..

1: there is alot of sloop in the c hubs and rear hubs, seems like the hingepin is a tad too small, has anyone else noticed it?

2: i filled the rear diff with 30wt oil, and its really loose, is it supposed to be that? (my previous sakura had far tighter diffs, but they werent the best..) the tc6 diff is by far the best diff i have ever built, just sanded the gears a little to get the back of them smoooth, its smooth! no run in required, nice!
i`m quite new to gear diffs, last time i raced for real was 8 years ago
