Repair Yakima Carbonite Rear Hinge Area 

Just repaired my Sears X-Cargo Sport 20 after watching a few of your videos and ordering the small repair kit. I had a stress crack near the rivets for the top right hinge. I drilled out the rivets, used the fiberglass and patch kit on the inside and exterior, and re-riveted the hinge back to the box. Couldn't have done it without the videos!! Thanks! PS - I am now proudly displayng my MammothMend sticker on my box.

I had the exact problem that you illustrated in this video. Your instructions were clear, camera angles were excellent and pitfalls were clearly explained. I had to separate the top and bottom. I purchased the small repair kit and was able to repair my cargo box easily. I also watched a few of your other videos. Between those and this one I repaired my cargo box with confidence. Thank you for these videos and an excellent product.

Thank you for sharing your repair! I’ve been struggling to perform a different mend to the latching system on a similar box (Skybox 21). I’ve drilled out rivers and dissected the latch assembly. A plastic pin sheared off of a collar which slides onto the latch shaft. Normally this pin links the external open handle to the rotating latch shaft…so the box will not open. There are no OEM replacements available from Yakima, have you found a mend?

What size rivets should be used?
