Changing hubs from oil to grease

[Scott & Heather]

I know this has been discussed before, but it now is relevant to me. My front hubs keep dumping oil. The inner oil deal was replaced but they still dump the oil out on the inside of the tire and rim and brakes. How involved is it to jus convert them to greased hubs?

Scott, I had mine converted by Choo Choo garage last time I had the brakes and seals done. Seemed simple then as everything was already apart. But then again, I wasn't the one having to do it. Craig

There is really no reason to change if the shop installed the wear sleeve,seal the proper way and checked the run out end play on your wheels they don't leak ? are they over filled people have a bad habit thinking one should fill till it runs out of the fill plug.I never have a problem with the wheel oil seals leaking (knock on wood)

If the new oil seals are not holding, it might be because parts of the hub are worn or corroded, or the spindle. Going to grease seals might slow the leak down, but grease gets mobile when it gets hot. My guess is that the surface that the seal mates to is scored, and wears the seal out quickly. Did that garage that messed up the hub bolts on one side do the seals too? There are thin stainless sleeves that can be put on in some cases.

Being an old truck driver, and virtually all front axle bearings on trucks are oil, I had my bus changed to oil bearings. That was 23 years ago and not one leak yet. Good Luck, TomC

I agree with Clifford, Walter and Tom!
There is no reason to change to grease if the seals are installed properly they won't leak!
And also as said there are "wear sleeves" to correct worn/damaged spindles.
Some mechanics call them "SPEEDY SLEEVES" (DON'T ASK ME WHY, just know that I've heard more than one grease monkey call them that!)

Some times the speedy sleeves are called two piece seals. That's the only way I go when I replace seals on OTR trucks. Using a proper seal installer is a must as well on those big seals. Some stores loan or even give seal installer away, just ask

Yes this is the same shop. They want the bus to come back in on Monday. I can't afford to keep having these mistakes happen. They waste my time even on the shop is covering them financially. I wonder if I can just fill them with oil and try to make it to another shop maybe choo-choo or something

That's your call, but it's a long way to choo-choo's, and depending on how quick it is losing oil, you are getting brakes wet and possibly suffering bearing or spindle damage. Maybe give them one more chance, unless there is someone else close by. If you run it knowing there is a problem, it will gnaw on your conscience all the way to the breakdown site.

I know this is kind of a Ford/Chev thing but I never had any luck with Stemco seals.  If they're not CR I won't use them.  The Stemcos always leak for me.

Sounds like the shop had a new guy work on your coach - Maybe he over-stated his abilities. Maybe they didn't know they needed to babysit him during the whole job.

At least they are trying to stand behind their work . . .


Maybe they are called speedi-sleeves because that is what they were called when SKF developed them  -

BTW, if the seal won't hold oil, then it will allow the oil in the qrease to leave also - leaving the soap base behind. Grease looses almost all of its lubricating properties when the oil is gone. . .

His MCI will have some are calling spedi seal,wear sleeve etc , but MCI calls it a  spacer the seal rides on I just replaced mine you take a ball peen hammer and tap round and round and you can pull it off with your fingers,clean the spindle up spread the sealant on the spindle and drive the new spacer on

Get Scott Crosby to come up and fix it !
Cody needs Scott's assistance up in the UP with his Iggle (rear end issuses) so you guys could split the transportation costs and just pay the labor your job and Cody could pay his labor! Win win for both!

I don't why people don't spend the 20 bucks on a C/R centering tool and install the seals I never have problems with leaking seals using the right tools
