I just recently got a replacement bearing for my Dv888. It worked great, reasonably quiet and totally unresponsive. But now it got loud all of a sudden. It is still unresponsive, just loud. Is this a normal part of a SPEC breaking in?
also, don’t all SPEC bearings have a little “YYF” engraved on the side? because mine doesn’t.
The noise coming from the bearing is fine. If you wanted to quiet it down, you could put a drop or thin lube into the bearing. SPEC bearings don’t have to break in, because they already come dry.
