Almost greased a customer's thru axle last Tuesday, and I want to warn every new wrench about it
Last Tuesday at my bench in Portland I had a guy's gravel bike up on the stand for a creak, and I stood there holding the grease gun staring at two spots: the thru axle threads or the hub bearings. I picked the threads because it was the fastest thing, and the creak came back in two days, which meant he drove 40 minutes back to me for nothing. What I should have done was pull the hub apart first, because the bearings were dry as a bone and that was the real noise the whole time. So now the rule at my bench is diagnosis before lubrication, every single time, no matter how simple the job looks when it rolls in. If you are new and tempted to skip straight to the grease, don't, because chasing a phantom creak twice costs you way more than the ten minutes it takes to check the hub. Has anyone else gotten burned by fixing the wrong end of a noise like this?
