Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / November 2004Can't find drum bearing grease - will disk grease work?
Hi. I've been searching through the car newsgroups on this topic without much luck. Some topics come close but no cigar. :-) I'm replacing the rear break shoes on a 95 Tercel. I figure I may as well repack the wheel bearings while I'm at it. All the greases at the auto parts store said "good for disk brake wheel bearings", but none mentioned anything about drum wheel bearings. The guy behind the counter at the parts store said you can use disk wheel bearing grease for drum bearings, but not the other way around. The grease I picked up is Valvoline moly synthetic grease. It's very black, thick stuff. The last grease I used was Mobil Synthetic grease which was red and not nearly as thick, and specified drum brakes on the tub. It seems to have held up fine, but now I can't find the stuff anywhere near where I live. Is the Valvoline synthetic grease ok for my rear drum brake wheel bearings? Why would the containor specify disk bearings, and say nothing about drum bearings? (I assume it's because drum brakes are going away?) Thanks, Stan > Hi.

If a bearing is used on a wheel that has either drum or disc brakes there is no difference in them. Providing their both of the same type. What does differ is that disc brakes create and dissipate more heat than drum brakes. That being said grease for a bearing that's used for a disc brake application needs to be able to hold it's lubricity properties in a higher operating temperature. So we can say that the parts guy is correct in that you can use grease labeled for disc brakes in a drum brake application. The grease just has a higher melting point and will actually hold up better in the drum brake application. You have to be sure to get the grease worked into the bearings well how ever. Brian Thanks for the info Brian. I figured it was because of the extra heat generated from disk brakes, but being the worrier that I am, thought it best to confirm that suspicion. :-) You have a good point about being sure the bearings are packed properly. Frankly, I don't care for this particular grease. It feels like sawdust mixed with peanut butter, and it's difficult to get it worked into the bearing. Do you recommend any particular bearing packing tool, if any? Thanks, Stan > > Hi. I've been searching through the car newsgroups on this topic > > without much luck.

But to be honest with you unless I have a lot of bearings to pack I usually sit down next to the truck and just slowly work it in by hand. By the time I've put the grease in a grease gun and then cleaned up all the grease mess that the packer makes it's about even as far as the time it takes. I little tip is to place the grease tub in the sun for awhile, depending on where you live that may not be possible this time of year. So next option is to set it next to some type of heating devise for awhile to soften it up. By the way I like to use the "Kendall Super Blue" bearing grease. It's easy to work with and holds up good, just my 2?.

Yeah but Amsoil is over priced crap! > "Yeah but Amsoil is over priced crap!" How's that if it lasts longer and works better? I can think of lots of other "crap" that fits your description. > > "Yeah but Amsoil is over priced crap!" > How's that if it lasts longer and works better?

Oh that's right it isn't, even Red Line, Spectro and a few other independent names can be readily found in auto and bike shops around the country. el Diablo >> "Yeah but Amsoil is over priced crap!" >How's that if it lasts longer and works better? I can think of lots of >other "crap" that fits your description. It's probably not crap but it is overpriced. And hardly any of it is API certified so you could void your warranty. Before the Scamsalesdroid jump on that with "Moss-Ferguson" ask yourself if you really want to have to fight a court battle over this when you could have just used the less expensive Mobile One and gotten all the same benefits. -- Elbridge Gerry, of Massachusetts: "What, sir, is the use of militia?

It's typically thicker and stringier, but has a lower melting point. Old-timers who know the difference will try to keep a can for rear wheel bearings. Most shops only use the one kind. I'd go with what you got. But if you run across some fibre grease, buy it for next time. Texas Parts Guy |
