We have seen a few of the first production run break like this. In the second run, which has been in distribution for about nine months, the threads do not go all the way through. There are no threads at the spot where the breakage used to occur.
Think about it some. The spindle is unsprung weight, so you want it as light as possible, thus AE's aluminum axle. By drilling our steel one out we get a weight almost as light as their solid alu axle. Further, a tube resists bending better than a bar, so the drilled axle should be stronger.
You'll be amazed at the force a 2 1/2 pound car at 20MPH transmits through a single point (the axle) when it hits something that is not supposed to move (the pipe).
We've had better (not perfect) results with the current 2601s. I think D.M.S. should have only the new ones in stock now. It was a running change.
