206 Torsion Problem

I bought my 2001 model pejo 206 about 2 years ago. When I bought it, the back of the car & nbsp; was standing too high in terms of appearance. & nbsp; About 6 months after using the tool in this way, the torsion was distributed, and excessive noises began to come from the back. For the solution of the fault, the steel bracelet & nbsp; on the right side of the shaft was dressed and the torsion ball was changed on both the right and left sides, and the sound was cut off. But now the tool & nbsp; obviously & nbsp; jumping and bouncing like a ping-pong ball in the back & nbsp; distortion of comfort. Tab bounce occurred after repair, & nbsp; this is because & nbsp; the rear shock absorbers may be off or not working, I am waiting for your help on the subject.
