Building the FT kit...

The bearings that go on the diff outdrives were quite hard to get on, requiring a gentle press-fit. They are pushed all the way on.

However, with the transmissions built and UNinstalled with NO bolts in them, just holding them in my hand, pinched between my fingers makes them bind a little bit and not free spin. Even relaxed, with no bolts in the case, they're not perfect. I'd call them "snug" when you go to turn them. Not notchy, just stiff.

When fully assembled w/motor plate, etc. they feel the same. There is no change (they didn't bind worse); but they're not totally free spinning like a traditional Stealth trans would be either.

Has anyone run into this before? Basically seems to be some runout in the main diff gear. They're not completely bound and not hammering on a hard spot, but they just don't spin freely like I expected.

Any input would be appreciated.

Also note I've been through all of the main SC10 4x4 page with all the build tips and nothing really mentions or applies to this.
