Took the tranny apart and installed into a 1991 stealth case. Still some play in the top shaft. Has to be sub standard bearings... I can live with it so I put it back in the 10T case I purchased aftermarket for the Re-Re. Top shaft runout was fine too..

Spur wobbles like a b!t@h still. Thing is just garbage. Going to try a Kimbrough aftermarket gear and see what happens....after we burn up the stock one.

I love the car but there are some quality issues I've noticed throughout the build, this being the main one.

Thanks for everyone's input.

didn't someone replace the entire slipper unit on one of these.

I took a short video of my original RC10 graphite w installed after stealth transmission from that era, 1990??? It has a Robinson Racing 84T spur installed. Thing rolls smooth as a Swiss watch. It's silly.

I'd post the video if I knew how.

Was rebuilding the trans in my B2 yesterday and remembered reading this thread. I too had a slight wobble in my spur gear (updated top with the B4). I never had an issue running it with the wobble, but it was bothering me. After checking everything a million times, I noticed the spring was not square. This was causing uneven pressure on the slipper assembly and the wobble. I replaced the spring with a new one, that is square, and the wobble went away. You can see in the picture how the spring leans to the right, ever so slightly.
