check rubber bushes on ends of rear shocks or the main axle bushes - these can knock when driving if they are badly worn
To replace the rear bushes on a Vectra, start by safely lifting the vehicle and securing it on jack stands. Remove the rear wheels, then use a socket set to unbolt the rear suspension components as needed to access the bushes. Press out the old bushes using a suitable tool or a hydraulic press, clean the area, and then press in the new bushes. Finally, reassemble the suspension, ensuring all bolts are torqued to the manufacturer's specifications before lowering the vehicle back to the ground.
To replace the rear subframe bushes on a 2002 Renault Laguna, first, securely raise the vehicle and remove the rear wheels. Then, support the rear subframe with a jack and undo the bolts securing the subframe to the chassis. Remove the old bushes using a press or suitable tools, and then install the new bushes in the subframe. Finally, reassemble everything by reversing the removal process, ensuring all bolts are torqued to the manufacturer's specifications.
In short you can't change the bushes on a Seicento rear arm, the design simply does not have provision for pressing the old bushes out and you can't purchase bushes for this purpose except from specialist poly-bush suppliers. It is substantially easier and more cost-effective to just replace the arm as a unit. If you do choose to replace the bushes you will need to cut/drill the old ones out and be prepared for a fight as it really isn't easy to do. The inner and outer bushes are identical.

rear suspension bushes worn, I had the same problem, a common fault easily fixed.
Can be a number of things, the first thing to check would be the Subframe Bushes
It means the rear trailing arm bushings are worn out and if that is the case the rear end won't track properly. The vehicle will appear to "dog" track.
The rear are easy enough and the front drop links but for the front anti roll bar bushes you need to drop the front subframe, quite a big job.
