Did 1h 40m and no squeak 🤞
The noise problem has not happened again since, so I can only assume it was resolved as a result of my cleaning and fettling.Did 1h 40m and no squeak 🤞
That squeak sounds like dried out ball bearing. Collapsed axle would either seize up or grind.I would have a look at the ReAxle kit. It replaces the non drive side axle, which is prone to cracking and collapsing. It's not "cheap" but it's not over £600 either
Fair enoughit is not just for the bearing because I don't have the required tools to replace the individual bearing cartridge.
The £66 is for a bearing assembly kit which is the part Garmin will provide, this is basically both inner & outer bearings and the circular metal assembly into which they fit (which I can replace).
If I had the requisite bearing press / removal punch tool and crucially the specific tool to remove the notched section that the hub pawls bind against during drive I would be happy to do just the outer bearing but alas this is the quickest and easiest route.
If the magnets & inside is all perfectly clean I can’t think what the noise could be. I’d be tempted to push another Rubber spare O ring next to the existing one just to put more space between metal on metal. I did that & it stopped a whump whump noise.Yebbut I don’t have the special tool to remove the serrated ring that the pawls bite into. anyway I borked the disk or magnets now since the original issue, see above lol. I will probably carry on tinkering to see if I can fix it eventually now I have a replacement trainer but don’t hold out that much hope.
Put the bearings in the freezer for 30 minutes or so prior to installation. It shrinks them a bit and helps.If you’re good with a little mallet & aluminium round bar you can actually tap the old bearings out. Then use a socket which fits over the bearing it might have been a 19 to gently tap the new bearings in. Carefully circling around to keep things flush. Saves you £60 for the full housing as the bearings are a couple of pounds each. You do need that special tool Shown to gain access though. I had it milled out specially.
Note the Zwift engraving 😎 eh?
I might try this but there are already 2 o rings on the spindleIf the magnets & inside is all perfectly clean I can’t think what the noise could be.
