I don't think they'll fit. It'll be cheaper to buy new ones, which you can get for under $100 both on Amazon https://amzn.to/4apIBZM Look around, maybe even cheaper.

I'm surprised you are having so many issues with aftermarket axles. Vibration and shaking is usually caused from the axle being out of balance. Try rockauto and carid to see how much the axle is. Also go to a carquest store and see if they can get you an axle from worldpac which will be like OE but cheaper.
