The way I look at it that the grease gets semi-liquid as it warms up ..
so the bottom of the housing is say, an inch deep in semi-liquid grease
and it naturally is getting to the ball and roller bearings.
I am amazed at how well wheel bearings last with the grease that they get.
I sure don't think just greasing either bearing and leaving the housing
pretty empty of grease will work very well.
the grease I have used lately ..
the last couple of years on several wheel bearing jobs is ..
either ....
Lucas brand 'Red N Tacky # 2'
Mulit-purpose EP Grease,
fortified with Anti-seize .
For maximum surface protection
540 F drop point
NLGI Automotive wheel bearing and chassis lubricant GL-LB
OR ..
Valvoline Crimson Heavy-Duty Grease Applications ....for
trucking, mining, construction, agricultural
NLBI No 2.
it also says NLGI Automotive chassis lubricant LB ..
those both work for me.
I do not use Disc Brake wheel bearing grease in the rear wheel brgs..
I use this more 'agricultural' red grease in the rear wheel bearings
..on german bearings..
and a good amount of it.
