I installed a Curt 120663 trailer hitch on my V60 today but don't know whether I did something wrong because I had to use a lot of force to pull the bumper cover into position behind the back wheels. I cut out some fascia where the receiver sticks out so I know that's not the issue. The thickness of the plates where the hitch attaches to the body of the car plus the spacers has moved the steel bumper back about 5/8 of an inch. Would that might be far enough to push against the inside of the bumper cover? I don't know whether to take the bumper cover off again to figure out what's going on or just leave it alone. Has anyone else had a similar problem?
