Damn, I wish I could have a brand new motor in my X5 for free!
All BMW parts, including motor and and tramissions, etc. have a two year warranty. The motor has a two year warranty with unlimited mileage.

It's a no brainer... put the motor in!

Any shop can replace the axles and bushings. They are commom replacement items. I replaced an axle myself with an aftermarket axle for about $120.00
