Rear trailing arm bushes.

I recently changed poorly fitted poly bushes for OEM. Should I have fully tighten the bolt which holds the bush, or just take up the slack to allow the bush to move?

It has to be tightened to over 100nm iirc and it needs to be done at a particular angle so that when the suspension is at rest there's no twisted preload on the bush. There is even a special alignment tool but I simply measured the angle of my cage before I took off the old bush and put the new one on the same.

That'll do for me. Thanks
