The flywheel was also running with a bit of a wobble. A replacement arrived a few days after raising a support ticket and submitting a short video of the issue.<\/p>\n\n\n\n<!--more-->\n\n\n\n<p>I have been using that replacement ever since and have covered almost 2000km on it for almost the last year and a half.&nbsp;<\/p>\n\n\n\n<p>Last week it started to make a few slight noises that I didn\u2019t like the sound of and a vibration could be detected through the pedals. The noise was a slight click and a rubbing\/squeal from the belt drive. The squeal was noticeable when the flywheel was coming to a stop.<\/p>\n\n\n\n<p>As it turns out is seems that the noises it had been making had been developing for some time but as it was gradual I didn\u2019t really notice straight away until it was pretty bad. I didn\u2019t realise this until it was fixed.<\/p>\n\n\n\n<p>Given the current world wide lockdown situation all makes of turbo trainers are in high demand and I didn\u2019t want to be in a situation of being without a trainer. Or even worse receive an equally broken replacement as a few users on social media have reported. Wahoo are also no longer sending out the DIY repair kit (K118).<\/p>\n\n\n\n<p>Now to save you reading on I have diagnosed and fixed the issue with parts that are readily available and using tools that I had.<\/p>\n\n\n\n<p>There are lots of great videos online that show the Kickr taken apart so I haven\u2019t bothered to show that.&nbsp;<\/p>\n\n\n\n<p>Kickr have acknowledged there is an issue with some units. It looks like my replacement unit also fell within the window of the dodgy batch.<\/p>\n\n\n\n<p>Now the information below relates to what I did to my Wahoo Kickr. The same process can be used to repair a Kickr Core with the same issues.<\/p>\n\n\n\n<p><strong>Notice:<\/strong><\/p>\n\n\n\n<p>Taking apart YOUR trainer is at YOUR risk.

The trainer has been used more and more over the last month as outdoor cycling due to Covid and the weather. I completed the Rapha Festive 500 cycling over 500km on the Kickr during between Christmas Eve and New Year\u2019s Eve. The trainer remains quite.<\/p>\n\n\n\n<p>13th February 2022. After a few thousand KMs the Kickr started to produce a click when warmed up. I know that once there is an issue it is best to investigate straight away. A dry bearing on the drive side was at fault. As the trainer was apart I replaced both bearings. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Wondering how to handle your Wahoo Kickr&#8217;s noise and vibration woes?
