the 75 grams of grease recomended (on mine anyway) is likely to be more than you would do by eyeballing it leaving you with less than recomended amounts in the car.

1 more or less won't kill you but assures you have enough.

I repack wheel bearings by placing bearing in a small ziploc bag with a wad of greese and work it in slowly. Hands stay greese free and I believe you do a better job this way.

This is probably true. I don't think you can get more than about 50 grams into the bearings and the raceways. The remainder would need to go in the cap. Anything more than 50 grams is a complete waste IMHO.

Cap is suppostd to have like 15 or 20 grams in it. full to the line (ridge)

50 total would leave bearings potientially dry or under lubricated when grease levels out under heat and centrifical force.

Stuffing more grease into the raceway than the bearing can actually sit in will not provide any benefit. You can probably get about 40 grams into the bearings. The remainder will sit outside the bearing, either inboard or outboard of the bearing, or it will sit in the cap. The cap can take quite a bit if you fill it up. I suppose you could use up 75 grams if you completely empty the cap of the old grease and refill it.

yes, you should clean out all old grease when you repack.

My wheels had no play in the bearing as adjusted, but I was rebuilding the front end and was doing new bearings and seals also. My old grease was as hard as soft margerine fresh out of the refridgerator. Replaced it with fully synthetic wheel bearing grease. ANd yes the pile of hard goop I scraped out was about the 75 grams manual calls for.

Definately the ugliest looking uncontaminated grease I ever saw.
