(Note: I'm deleting a similar post from Bicycle Mechanics due to no response. I know several who post here use WI hubs)
I've developed some lateral play in my rear hub(MI6). I've disassembled and understand that the lateral play can be taken out, and the sealed bearings appear to be very smooth. Anyone know what causes this play to occur? Something must be wearing one would think. Has anyone else experienced this? I know Tandemgeek recommended in one of his many excellent posts adjusting the hubs after some miles, but mine had gone almost 8000 miles without any problem whatsoever.
My (tandem) LBS has seen this when the hub was installed in spread dropouts, but I measured my dropouts with a micrometer and was only .7mm over 145mm. Left the wheel at the LBS to reassemble, but these hubs are obviously pretty easy to work on. I've been planning on buying a second wheel set in any event and will be using these as backups or for rough roads.
BTW, this explains why my RD shifting had deteriorated. What a relief.
