Rugging while braking and driving

hi, for some time now I have heard the problem that when I drive straight ahead and when I steer slightly a light jerking, tocken(is hard to describe). it doesn’t always occur, only sometimes. same is the brake, when braking from high speed (from 100km/h) this jerking is also there and the whole austo viebriert during braking(braking only before about 5tkm new) When driving back this regularly gives off a loud noise, but I think the error is the transmission and not this now I have to find this mistake only I don’t know what can be yours. Wheel bearings feel something different and is in left/right curves louder or keep away(So I know that at least) has one borrowed a tip what it can be??
