ParticipantIf its making bad/loud noises its likely that the bush and bearing are shot.
Before you tear it down, grab the big sprocket on your cassette and rock it to check for play. If you see movement your hub probably has the chronic Mavic bush wear. They use a nylon bush as the inner bearing, and once enough road frass finds its way past the inner seal that bush wears down. The best solution is to rebuild it with ceramic bearings using this kit – http://www.ebay.com/itm/NEW-HUBDOCTOR-PRO-MAVIC-FREEHUB-REBUILD-KIT-HYBRID-CERAMIC-BEARINGS-/330940493909
I did mine early this season and its been silky smooth ever since. Here’s a bit more info – http://bikearlingtonforum.com/showthread.php?7034-Rebuilding-Mavic-freehub&p=85786#post85786After being stumped by the fact that Mavic’s mineral oil and Perdo’s Road Rage mineral oil are both unobtanium, I went hunting. Turns out LQ5 is a good weatherised and filtered lubricant that works perfectly on the Mavic freewheel hub.

McLean Hardware has it in stock – 4oz bottle for $5.00, but you are welcome to use mine for the few drops it takes to lube the pawls. I’m in McLean.Likewise if you are a bit antsy about rebuilding the hub just grab the kit and bring it over to my place. It takes a bit over an hour to do it, and most of that is cleaning parts.

Thanks. I may try the re-lubrication first because I have spent enough on my bike lately.
August 19, 2014 at 2:49 pm #1008265ParticipantIf the bush and bearing are worn then no amount of lubrication will solve the problem. Check the play by rocking your cassette. If there is movement, you now know why. It will also be wearing your cassette and chain at a higher rate too.
August 20, 2014 at 3:18 am #1008351ParticipantThe hub is pretty solid, which brings me back to the original question – is drug store mineral oil the same as the bike store stuff? I’m guessing not.

ParticipantI don’t think all mineral oils are the same. Google result suggested sewing machine oil would be right viscosity – but may not last as long?

ParticipantAs a woodworker and owner of soapstone counter tops (which like to be oiled occassionally) I can say that drug store mineral oil is a little different than regular mineral oil. Drug store mineral oil pours thicker; it’s sold as a laxative and is fortified with certain vitamins. 100% mineral oil without additives can be found at Woodcraft, a woodworker store with 4 or 5 locations around the fringes of the Beltway.
Johnson & Johnson baby oil is just mineral oil with fragrance. It’s viscosity is probably closer to 100% mineral oil than the laxative kind is.

I’m in McLean.Thanks for the offer, and thanks to you and Brendan von Buckingham for the information. I’m in Alexandria so I may see what I can get at the LBS or the hardware store, or maybe try Amazon.
August 28, 2014 at 6:33 pm #1008851ParticipantFYI, pulled the hub apart, re-lubricated it, and it seems to be working fine. I used sewing machine because my LBS did not have a specific oil that they sold for hubs and we had the sewing machine oil around our house. I wasn’t sure whether I would be able to get a wood oil with the right viscosity. Apparently, a lot of shops use Shimano disc brake oil. Thanks to everyone for the encouragement and advice.
