Any insight about whether molybdenum grease (used for CV joints, etc.) is compatible with other types of grease that might be used on wheel bearings. I've read that some greases are not compatible with one another and that mixing two such incompatible greases in the same application can result in grease breakdown and zero lubrication. I'm curious about this now as I am preparing to replace my rear wheel bearings ['82 245]and would like to pack them with a high-temperature molybdenum grease, but the new bearing sets arrived with a light application of something lighter which appears to be a lithium grease. I can't get what's in there out, so I want to know if I should be concerned about producing a bad mix. Thanks for your help!
