It's amazing. Sometimes I find that I don't even know what I don't know. I just found out that you can't mix different types of grease.
I started out with this red grease...
... and later, just because the local Pep Boys store had a tub on the shelf, switched to this red grease, which I can no longer find at any local auto-supply stores.
Now I see a warning on the back of the Mag-1 container that says, "IMPORTANT: Do not mix greases of different type. Use a solvent to remove and clean out all traces of incompatible greases before repacking." Oh, swell.
Okay—there's no way I'm going to be able to get the old grease out of the Hyatt bearings, so apparently, what I need to do is find a readily-available type of grease that is compatible with Mag-1's "High-Temp Disc Brake Wheel Bearing Grease."
And now, the know-nothing newbie's stupid question: What's compatible with this stuff?
My Favorite "compatible"grease.
Wolf's Head Red. High temp, the works. Available.
The Timken might be the same as the red grease sold at all auto parts stores. I think it's marked as Chrysler grease.
This is my favorite brand.
Made for cars from all over the world.
So it's just fine for "The Universal Car"
Use only period correct NOS lubricants......
I doubt you will have any problem mixing the modern red greases. I haven't. I have zerk fittings on the rear axle and use any modern chassis grease. If you mix modern grease with old style long fibre greases you might have some incompatibility. The long fibre greases have no water resistance and water quickly turns them to soap.
Both the Timken and Mag1 are lithium complex greases. You should have no problem mixing them.
You can find the spec sheet for the Timken at:
