Think they may have gear oil with special seals and would not use grease--at least my bus has that type. Not sure what kind of coach you have.
One way to tell is if there is a small diameter hex drain plug on one side of the front hub outboard of the seals. This would be the hub oil drain/fill plug. Good luck. Henry |

Substitute the word "setup" for "coach". I hate getting middle aged. He he he. Thank you. Henry |

The manual for the 4104 calls for grease on the rear wheel bearings. There should be an inner hub seal and an outer seal that seperates the bearings from the axle lube at the end of the axle tube.
The manual also calls out grease for the front bearings.
I recently disassembled my 4104 rear hubs/bearings and found the same condition you describe. I suspect that the outer seal was not doing its job. The fronts were converted to an oil bath. (apparently this was Greyhounds prefered method for front bearings)
However, both front and rear wheel bearings can be converted to oil bath lubrication instead of grease. For the fronts to be oil bath lubricated a 40w or 50w oil is added through a plug hole in a special sight glass hub cap bolted to the end of the hub. For the rear the outer seal is removed and the bearings are splash lubricated by the axle lube. In both cases the inner seal needs to be changed to a oil bath seal in place of the grease lip seal. The Chicago Rawhide substitute oil bath seal is a "Scott" seal. These seals are also a good choice anytime there is wear present on the spindle seal sufaces.
The choice of grease lubrication or oil lubrication appears to be both a manufacture and maitainance opperator decission.

Put differential lube, 85-90 wt is all you need. Don't put motor oil-- it does not mix with gear lube.

For the old PD-4104 wheel bearings front and rear.
The wheel bearings need to have a good quality wheel bearing grease.
Some folks change the front bearings to oil instead of grease but in the case of using the bus every day this will work fine.But most of the 4104's are now in use as a motorhome conversion.
The oil drains down from the top of the wheel bearings leaving them dry till you use the bus.
Where as the bearing grease stays where it's at.
The rear wheel bearings need the same grease not 90 weight gear oil.
The fill plug on the differental is lower than the axle tubes so no oil can get to the wheel bearings.
So this means you have to use wheel bearing grease.
The old PD 4104's work fine this way it's hard to improve on something that has been working like this for 50 years. |

Oil Seals -- I think my 4106 came with oil bath system on the front (the sight glass hub cover & rubber plug) but had grease only in them & grease on the rear. I too have read for the not daily use grease is better...so I have been using all grease for front and rear. Be advised there is at least one brand of oil seals (Stemco) that comes with a slightly oversized seal and a new "rub" ring that press fits on over the old ones (most vehicles of this age will probably have bad groves and / or rust pits worn in the original one). If you need to find part numbers remember to bring the existing bearings (preferably cleaned) to the truck parts place you shop at -- they can tell what seals you need by the size of the bearings. Of course if you're lucky enough to have a parts supplier specializing in bus stuff would be even easier. |
