Wheel Bearing Grease Question
« on: November 05, 2013, 01:44:45 PM »
Is there any problem using wheel bearing grease specified for wheel with disk brakes on our cars with drum brakes?  I have heard that wheels with disk brakes operate at higher temperatures, and if used on wheels with drum brakes teh grease might not flow properly in the bearings.  The reason i ask is I like to use synthetic grease because it is more stable and will last longer, but I have not found synthetic grease for drum brakes.

For over 50 years I have used a product called MolySlip. I believe it was at one time called Mr. Moly in the U.S. It uses molybdenum as the slip coefficient modifier in a base that will not melt even with a torch blasting at the stuff. (I've tried it.) You simply melt out all the original mineral grease with a propane torch and then push the bearing down in the MolySlip can until it oozes out the race. Reinstall with a good smear on the race faces before putting everything together. You will NEVER have to grease the bearing again and it will NEVER chew down it's races. NEVER. And the vehicle will move easier with this stuff in the bearings. I don't know why more people don't use the stuff. It's been around for many years and can also be bought under house brand names at different automotive stores although I prefer the original MolySlip. NAPA handles the MolySlip brand up here. They also put the stuff in cartridges for grease guns. I shoot this stuff into steering knuckles and such and NEVER have any failures or wear. It's all I've ever used since the mid sixties. You see people sitting by the side of the road with small utility trailers disabled with burnt bearings? I've never had that happen and I load the trailer with a 1/3 of a bush cord of wood in Summer 30C weather to bring home 5 or more cords of hard wood. And I have never reloaded the bearings in 20 years. MolySlip also makes this stuff in an oil carrier called "MolySlip G" for gears. The G is used as an additive for manual trannies and rear ends. The tranny will shift easier especially these old crash boxes. I shoot it into universals and never have to service them again. When I buy another "new" modern daily driver,the 1st thing I do is pull all the bearings and put this stuff in. Same with the steering knuckles. And 5 or 6 years later when I sell it I have never had any bearing  or steering wear out.
