Here is the situation.

I got bubble on my goodyear after being towed away.
so I went to goodyear shop to get warranty on the tire.
while it was getting replaced, I found the bend on my pass side front wheel.
So I went to fix the wheel at local wheel repair shop and the wheel got cracked by then.
After fixing, one of the guy working there said the thread of the hub is damaged and showed the messed up lug nut to me.
and he said he can't do anything but cleaning inside of thread might fix the problem.

I had an appointment at dealer after two days.
so I thought it wasn't big deal and probably solved by dealer easily.

now. my car is at dealer. after the inspection SA told me the thread of wheel hub is wrecked up and needs to be replaced.
and the cost of doing so is almost $700 plus tax.
I got the estimate paper and part were like $400 but the labor was $300 (didn't start the job yet)
Is it reasonable labor fee they are charging me?

after I heard the price and damage, I talked to goodyear store manager about that.
he said he can fix it, so bring the car to the shop.

what do you guys think?
should I just replace it for safety matter?
or give the goodyear chance to make thing corrected? (he said if something goes wrong, they gonna replace it)

if the replacement is the way to go, should I do it dealer for that cost? or any alternative way?

any helps/recommendations/comments appreciated.
thanks
