niki says: the AC never worked (i think the PO fibbed about that), but otherwise she ran perfectly until last month. the heat is off, which i'm hoping is due to the alternator/voltage regulator problem. and of course--this supposed wheel bearing issue.
i'm trying to figure out: do this NOW, or wait for nice weather. how do i know if it's urgent?

You need a gauge with the little lever (i forgot what it's called) and a magnetic mount - I got mine at Harbor Freight for under $30 i think. It took a little math to convert the metric units in the manual to the gauge units but basically you are checking for play outside the spec. It's a pretty damned precise way to set wheel bearing load - on mine, an eighth of a turn of the nut was all it took to make it go out of spec. Otherwise, new seals, Mercedes green grease if you like (one tube for two wheels I think it is) and off you go.
