How to Correct Rattling Hitch on 2021 Mazda CX-30
Question:
FYI the recommended rack for my Mazda CX30 turbo is causing noise. It sort of fits, but does not seem to provide enough clearance on the drivers side for the muffler bracket. You guys might want to look into it.

We've actually seen this before on other trailer hitches, but it's likely going to fall into one of the same fixes for the # DT64MR on your 2021 Mzda CX30. I've linked a helpful article we've put together on fixes like this but you can either re-position the exhaust hanger by unbolting and repositioning to adjust the exhaust so that it is not coming into contact with the hitch. This can be achieved by unbolting the hanger, flipping it and bolting it back to the frame; you can also do this by adding washers or spacers to lower the position of the hanger in order to move it to the left or the right.
If the rubber exhaust hanger has been stretched out and that is causing the rattling, you can get a replacement at your local auto parts store. Replacing your isolator with a shorter one will raise your exhaust's position. Replacing your isolator with a longer one will lower your exhaust's position.
