CX-9 OEM Roof Cross Rails Installed

:
Mazda CX-9 Grand Touring 2016
And, the bars are tear drop shaped in cross section. The fat round edge goes forward; the slim sharp edge goes back. Yes, you want some ability for the bars to move in the end pieces.

My crossbars were very snug even without being tightened down. The crossbars have a very specific position. One each for the front and back. And, they have designated left and right attachment points. Either you may have reversed them front to back or turned it around… Or maybe the roof rails are not snug?

I also purchased used factory crossbars that came with no hardware. This is what I ended up buying. It’s a really tight fit due to the length of the hardware and the curve/contour of the cx-9s roof.

My eBay link didn’t work. The title of the item is:

(x4pcs) M6 x 25, Button, Torx, Black, Washer, Screw, Shoulder, UTV, 6mm​

The installation of the cross bars was super fun for me. I ended up using a lighted mirror so I could see what I was doing. Just installed my Thule ski rack today as skiing starts here at the end of next week.
