...I'll stick my neck out there and say that if its "wobbling" I don't think its a bent axle....but I can't say its not bent either.
You haven't said if you checked the tie rod ends or pittman arm or other steering components. Hey, at this point I'd check to make sure the lug nuts are on correctly and that the rims are not warped ect ect. A good inspection may reveal more.
Just my thoughts. Not saying the mechanic is not good but even the best miss something once in a while

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
