If the bearings are that loose, there may well be damage to the races
& rollers. You really need to disassemble them to look. No, grease
will make no difference to a wobble. There should be NO wobble.

If you can rock the wheel back & forth (in & out at top & bottom),
then the bearings need attention BADLY.

If there is no rock, then you mean the wheel is not straight at the
rim when spun. This could be a bent wheel or stubaxle or badly warped
drum. A bent wheel may cause a shudder at some speed range when
driving along (though my 57 had zero shudder but eventually I found
that BOTH rear wheels were severely bent, and looked horrible when it
was driven past me!). A bent axle or drum will almost certainly cause
a shake. Loose or worn bearings won't ; it will only make a noise if
the race is pitted.
