I know what you mean! But...I bet you were installing on the ground doing one side at a time? And it was the second one you couldn't get in, am I right? You just have to let the whole control arm droop and install them both at the same time because it's a solid rear arm not IRS, and once it's all together on the ground again reach under and undo those trailing arm bolts on the chassis so its just loose then crank them back up nice and tight, you do this so the bush lines itself up to your new ride height and isn't trying to rip itself apart as it will be twisted until you loosen the bolt,
