[TowerTalk] Best Grease for Rotor bearings ?

[Bob K6UJ]

I also use wheel bearing grease to lube my thrust bearing.  25 years of service, no problems.

From what I've read, mechanics advise NOT to mix grease types, so I stick with wheel bearing grease which is usually available in both sizes of tubes to fit a hand pumped grease gun and a lever action one.  I've also redone the front wheel bearings in my car with the same grease.
