Bent wheel studs!! No it is not safe to drive. Now way would I drive this vehicle until I replaced the bent studs.

It is never safe to travel with a bent subframe. Once a major suspension piece is damaged you run the risk of further damage to parts that may not be damaged already but once structural parts are damaged they must be replaced because they are not going to hold up in another accident.
Yes, it could may mean the car is not safe to drive, have it checked/repaired by a good garage.
No, if you get into another accident the frame will collapse further, and could cause damage to the occupants. Driving a vehicle with a bent frame is also harder to steer because it interferes with your alignment in most cases.
If it is a rear wheel drive car you could have a bad U joint, bent drive shaft or a broken tooth or two on the ring and pinion gear. If it is a front wheel drive vehicle you may have a bent rear axle or bad bearing. If it is four wheel drive or all wheel drive you may have a bent drive shaft.
Yes, it is.
No
Remove the Subframe. Subframe should be removed but it can be done by lowering Subframe down. I recommend removing the Subframe. Do not pry in oil pan with a screwdriver, get a rubber mallet, it is glued in place.
The opposite of drive safe is careless driving.
Yes you need to remove the subframe to remove the gearbox on elantra. the motor must be supported at the top before u remove the subframe.
Can be tire out of balance, bent wheel, defective tire, broken motor mount, or bent drive shaft.
