Yes, the aluminum strut on that rack is less than optimum, I think. You're not the first person I've heard having trouble with that rack. I had that rack but didn't use it much, so sold it off a few weeks ago.
Tubus makes a similar rack in cro-moly, by the way. But the steel strut should help the Axiom be more reliable.
