rear wheel bearings

[pen9jamie]

hi,,had my m3 since october..and the bearings felt good...come november they were very tired....so replaced them plenty of grease...i got back today after a 2hr run and there is play in the back wheel,,,(only very slight),, i was told they like to eat bearings but is this the norm,,,600km,,,i do ride lots of quarrys but still seems harsh... maybe just bad bearings

Sounds like bad bearings to me, did you get them from a bearing factor? they maybe the correct size but not for high speed use, also check you haven't missed any spacers out etc when you put the wheel back in.

Don't use your jet wash near the bearings, they will last much longer. I used to go thru' bearings like mad until a tip off some years ago.

It is possible that you over-greased them (though admittedly unlikely). If you put too much grease in it overheats.

Personally I always use the -2RS variants of bearings, as they come with just the right amount of the right kind of lubricant already installed, and the extra oil seals can only help.
