Hello again.
Yes, an alignment after the repair is a good idea after having the suspension taken apart and put back together. It's hard to guess the life of an axle because of so many variables like road debris, weather, etc. My mothers Lincoln had an axle fail at 40,000 miles due to a plastic bag wrapping around it and tearing the boot. It then lost all the grease and started making noise. I've also seen them last the life of a car. You never know. Keep us updated and let us know if you have any further questions on this issue. Hope this helps and thanks again for using 2CarPros.
