Broken axle after accident. Safe?

I don’t see any problem with replacing all the damaged parts, is your insurance company comfortable with it?

The body shop may well subcontract the axle repair to mechanical shop, possibly even a dealership. That’s how ours operates.

 

Replacing an axle.... IMO no big deal.
Ditto for the A-Arm.
I would say safe.

What to look for?
Are the mounting points for the A-Arm bent?
Was the transmission case isolated from the breaking of the axle (assuming you meant the front)?
Will they relace any rubber suspension components too?
Does the car align within spec?
No mention of the struct being damaged?
In those regards, if you wish to go "a step further", yes, bring the car to a different alignment shop for an inspection and measurement after the repair. But that cost will be your responsibility unless they find issues then you'll re-involve your insurance.

So, A-Arms and axle replacement IMO does not require selling/ trading the car.[these are standard repairs].
But collision damage, and its tendency to bend things, is more concerning to me.

Good luck with your decision.

 

Again, you shouldn’t need to oversee the body shop. If there’s suspension or mechanical damage, beyond their scope of expertise, they will (or should) take the initiative, subcontract that work to a shop competent in those areas.

 

Beware of clunking, popping, and squeaking over rough roads. If you experience any of that, take it back for a rework. Also look for your anti-skid lamp turning on abnormally or more frequently; that's also an indication that the suspension isn't set-up correctly.
