My blazer will not go into 2hi anymore, when I tried to put it into 2hi it just blinked and went back to 4lo. When I drive it the car jerks and is very erratic.

my blazer was recently in a minor accident where a friend hit a curb and possibly did major damage. Any advice or help would be appreciated.

If you are driving in 4lo, it will be very jerky because of the low gear range you are using. The vehicle shouldn't be driven over aprox 25 mph in 4lo.

As far as the problem, have you checked to see if you are getting power to the actuator on the transfer case?

I did not, and I dont really know how. But recently my friend hit a curb with the front tires pretty hard. And 2hi stopped work and the jerking and wobbling started to happen Im thinking its off set or somethings wrong with the axel or wheel alignment but im not 100% sure.
