The broaching of the internal splines will create stress risers.
But what broke the part is simple, the sockethead cap screw has been overtightened, probably more than once. |

If the part is designed properly, overtightening the screw wouldn't break it there. The aluminum would bottom out into the splines and further tightening would just strip it or snap the aluminum between the screw and sway bar. It does look like overtightening did it though, but only because the ID of the aluminum was too large. That part that broke sees the most stress during tightening, even though it's not the thinnest part.
I don't like the idea of clamping something onto a splined shaft like that, it will never distribute the load evenly and knowing where the stresses will happen is a crapshoot and completely dependent on mfg tolerances. Either use a press fit or just oversize the part. |
