It came without an axle, but I found some for it.The bearings on the axles seem fine, but should I change them anyway? What about the seals, change them too? Am I forgetting anything? Please help, I want to be driving again real soon.

You know what ya need to do. Yes replace the bearing or at least the seals on any part you buy used. Why would you want to take a chance with any of that being bad? Make sure the axels are not bent!!! Don't forget to used posi safe fluid and change it before you put it into the car!

Also, make sure to use some loctite on the axel retainers. Hope this helps!
