V6 Capri Rear near side track rumble on acceleration after rear end rebuild.

Hi All, I have just renewed all the bushes on the rear springs / shackles / sandwich pads / diff location arms. Have not replaced rear shocks. When testing the car I now have a rear near side rumble tramping sound and feel upon acceleration. I assume I have not lined something up correctly or tightened wrongly. I did put car back on the ground before final tensioning of all bolts as per manual. I have noticed the centre bottom spring bolts through the sandwich pad are not completely centred through the centre hole. I found it too hard to move and centre it all when all connected. Could that be my issue?  Any advice well received.  PSR

    rear arm bushes are eccentric, there is a specified distance between mounting points you need to measure and rotate the bushes before pressing them in, so check your diff angle at the rear uni in case the tailshaft is not level

    Hi gtv6capri, rear arm bushes as in the rear spring bushes? So measure both side spring lengths between front n rear spring bushes so  that both side distances are the same?
