I’d been having issues with one of my roof bike racks (Yakima King Cobra) not holding the wheel securely … although it would “lock” into place for a specific wheel diameter, I always found it had migrated up towards the larger size after travel, leaving the bike able to move around in the tray.
I had asked Yakima if they sold the parts separately but they’re unavailable apart from buying a whole new roof rack. Looking at it closer, even if I had new parts, it wasn’t clear to me how I could get a new plastic holder in between the metal tubes. Customer service did offer to work out a deal on a new rack, but first I tried to save the $$ and come up with a fix.
Seemed to me the red locking cams had too much play, and if I could tighten up that clearance things might work.
A trip to Lowe’s for clevis pins and pin clips. Just a bit larger than the original rivet (seen at the right – drilled out)
Next I had to drill out the red cam and the plastic wheel holder a bit for the larger diameter clevis pins. Installed with a pin clip to keep it from backing out… voila! Both cams lock into place much tighter and the wheel holder doesn’t slide.
Not bad for $5 in parts. Before and after (right) below:
