could axle cause a vibration?

[Mustang Ricky]

ok, i have a speed related vibration. the tranny and mount are new. the driveshaft is the aluminum Ford Motorsport. i still have a vibration via the gear shifter at around 70-75 mphs. could the rear axles cause the vibration if they're bent? anything else that I could check?

I had the exact same problem you have. It ended up being a worn out pinion bearing and race.

the pinion bearing and race are located in the rear, right? I'm pretty sure those were replaced when i had the gears done. it vibrated before and after the gear work.
