Third member came loose
 

So, I ran my first gen at a track on Friday for about 3 1/2 hours (seven half hour sessions) and the third member came loose from the housing. The car leaked 90w like a siv and was finer after i tighten all the rear end bolts. I have read about this happening before on the Forum.

What do you racers do to stop this from happening?
Thanks

I had this same problem for a while. Getting my driveshaft balanced cured it.

Good point, I had not looked into that!
