I have a curt hitch on my 2013 CR-Z
I don't use it to tow anything so don't give me shit about that. I use it for a hitch mounted bike rack to hold my mtn bikes. My rack and bikes are well within the tongue weight limits and all that crap.
The hitch mounts to the "frame" with two bolts and uses a bolt and bracket to mount to the tow hook. The tow hook brackets are approximately 3/16" too far apart and they are too thick for the bolt to squeeze them together to pinch the tow hook.
Part of me thinks it was designed this way on purpose, I'm thinking the bolt through the tow hook is only there to keep the entire hitch from falling off the car.
But at the same time it can't be designed that way because the "frame" is too flimsy so the whole hitch moves. It moves so much that my bike rack will move about 4" up and down.
I solve this problem by using a cam strap to pull the rack up so it won't bounce all over, but I'd really like to fix the actual problem.
First thing I tried was adding washers in between the brackets, but the bolt can't squeeze the bracket tight enough to pinch the tow hook.
I tried wedging something in between the tow hook and brackets perpendicular and parallel, but that didn't work either.
I've tried everything I can think of except cutting the welds and welding the brackets closer. I'm not sure that will work either since the brackets are so thick the bolt can't bend them anyway.
Do any of you have ideas before I take this shit to a shop and have them weld the brackets directly to the tow hook.
