While driving my car, it shifts from the rear . on any little crack or hole.... What can it be i changed two parts already , the ball joints and four like arm parts that are under the car.. what can i do to this point .. car can not drive more thann 30 mph... most say alignment wont help
I would start with having the tires road force balanced to determine if there is an issue with the wheel or tire assembly that is contributing to the rear end shifting. A road force balance applies pressure to the tire as it is spinning to determine if there is a soft spot or other defect in the tire. A regular tire balancer will not necessarily assist in this.
If the tires are good, check the rear control arm bushings. Any excessive movement in the bushing can cause this issue.
Also check the struts. A weak spring/strut will also cause the rear of the vehicle to move around excessively.

I recommend taking your 1994 Honda Accord to a reputable auto repair shop. Make sure they can professionally diagnosis the vehicle for you to know what the cause of failure is and be sure to tell them all your concerns about the car. They might be able to give you repair options. Even though you already changed two parts, a new problem could have developed. . This way they will be able to tell you all the facts and you can make the best decision for your vehicle.
