Hi Steve,

I don't have any experience with rotors, but a car repair shop is going to 
charge you an arm and a leg for something you can probably do yourself.

Go to AutoZone and pickup a can of heavy engine degreaser (the red can w/ 
orange lid is the good stuff).  You can also pickup a can of wheel bearing 
grease (should say that on the can), and use that to repack the bearing.  If 
you don't see the grease just ask one of the employees and show them what 
you are using it on.  You can also get this stuff at any store that carries 
auto supplies.

Hope that helps...

Subject: [amsat-bb] Thrust bearing maintenance

I have an Yaesu GS-050 thrust bearing that has been installed for about 15 
years.  The thrust bearing turns, but requires a lot of force.

I disassembled the thrust bearing to find that the grease is very sticky 
(think candy apple sticky), and not lubricative (if that is a word).

Should I take it to an auto repair shop and ask them to degrease and then 
lubricate similar to repacking a wheel bearing?

What kind of grease should be used?

Thanks and 73, Steve N9IP
