My 9-3 is dead need input please

hello,

i pulled my 04 9-3 linear out the driver way then 2 BIG BANG sounds & now the check engine light is on and i can not go faster then 5Mph wheels are still solid
engine has oil i can for forward & i still have reverse

anyone have any idea what this will set me back? it got well over 250k miles on it not sure if i should just get a new car or not

.. oh yeah the wheels are still making a snapping sound when i turn left or right bad axle?

Thanks,
