So there is a component in the diffs that is not consistent from part to part. We have narrowed it down to the big shim under the bevel gear (TKR5145 - 6x17x.3mm shim). We looked at a few of them (new) and noticed some are warped (coned up or down). Others are flatter. We then looked at the same shim from a heavily used (smooth) center diff and it was totally flat. That inconsistency in the shim is pushing the bevel gear into the diff mesh causing the irregularity.

One of the center diffs at the track was pretty tight - not smooth, but after breaking it in for 30 seconds, it made a huge difference and was waaaay smoother. The short break in time flattens the shim out and the irregularity went away. Their car is good to go and they are racing tonight .

NOTE: This seems to only affect the center diff, which makes sense as the plastic gears can distort and warp (they all do). For what it's worth, we put one of the steel spurs on one of the production center diffs and the diff felt normal.

Ironwolf, PM me your phone number (or email us at [email protected]) and we can see if we can work through a solution. We'll send out whatever parts you need to make sure the car operates as intended.

We expected to have some issues, but the diffs weren't one of them . We tested this car for almost a year but it seems the production diff parts are just a little different.

We are confident that after the center diffs are broken in and used that they will be smooth.

Let's all help each other get the information out and work together. I hope everybody knows that we are on this like flies on $#!+. If anyone else is having issues after breaking in the center diff, please let us know.

Thanks.

The TKR5146 shims are the ones I put in, and the TKR1222 are the ones I was trying to leave out lol.

So total idiot me put it together without the 5146s and it is grindy but will be fine once broken in.

Continueing with build lol.

Ok so I think my left rear drive shaft is warped, it looks like it wobbles when I rotate the wheels. Is there a way that I could have screwed up that drive shaft?

These public forums are powerful and can seriously hurt a company and the potential future sales. Try hitting Danny up in a PM or email as i am sure he is biting his nails waiting for feedback anyway. This is a big thing for Tekno and whatever problems may occur, he will take care of it. He obviously stands behind his stuff so lets cut him a break. PM is the way to go. If there are any legitimate problems, he will post them on here for current and new potential customers and what the fix is.

Check out this build documentary of the EB-48 from another forum. I'm very impressed with the parts quality and I have yet to see it in person.
