when its happen to me whit my old 5gc 1991, (paid 300 buck) i didnt want to spend money , so i fix it for 0$ in 10 minute, putting whit hammer some little nail inside around the bushing,

and cut some rubber in circlev( buy strap rubber and cut it) and put it on the back of the bushing and put back the bolt whit some washer to push the rubber , it will affect the movement if you tightened too much, but
pro- its work, no shaking no more
cons- u lose comfort and stability, since its metal to metal, and no more bushing
but u feel more the road from the rear, not a big difference for normal driving,
u have keep the wheel centered to keep alignement- tough (u can change the alignement later whit some more pin inside the bushing
but i wont suggest to do that,
but for someone who dont have money or want to fix it now, it can help
that least on my old celica till she died
