My front seals are leaking. Because the front hubs on my 06 are oil-lubed rather than grease , do I need special seals . Also the RH seal was replaced when I took delivery about 10K mile ago. Because they are leaking so soon (10K miles), might I find a bad spindle or something when I disassemble, or is that about what I should expect?
Thanks, Joe |

Like most things on a coach , Sitting unused is Death.
The old style trucks and coaches used simple seals & grease , and worked fine.
Then the ability to have a "see thru" cap made the use of oil in bearings a better deal as the rolling resistance was a tiny bit better , and a driver could check the unit , with out bending down .
However well these work in a commercial unit doing 200,000 miles a year , they suffer from two problems , long sits make them leak , and when they leak , you HAVE to replace the linings that get oil soaked.
Today life is better due to chemistry, synthetic grease resists water so the old style simple seals , that suffer less from sitting, can be used.

Hey Fred is dead on it there. Only thing he forgot is that they also collect water, I think it is from condensation, when sitting.
Changing back to grease is highly recommended, one greasing with good grease will last for years and years, even if it sits, and it never leaks. |

I see no evidence of leaking on my '74 Flxible transit seals. And I don't know if I have grease or oil seals. However, my bus sat for 9 years before I bought it. I think I should take it in and have the seals replaced just as good PM. Does this sound prudent or should I inspect something before I have work done?
BTW, I do most of my own work, but removing wheels is not something I can do in the storage yard without raising some eyebrows. . . So I have to pay a garage to do it. Or can it be done without taking the wheels off?

scott, your seals more than likley are grease, the oil type covers have a round plug in the center that you take out to check and add oil if required. as fred stated for us bus types the grease ones are the best as we sit for long periods of time without the wheels revolving to keep a coating on the bearings and moisture getting in as condensation rusts the rollers and cages of the bearings so i would stay with the old tryed and true i took mine off and went back to grease. mel 4104 |

hi john, no it is very simple to go to grease, if your front wheel covers on the front hubs do not have therubber plug in the center then the chances are that they are grease seals in the hubs now it is very simple to pull the front wheel off then undo the 6 bolts that hold the hub cover on ,pry the cover off with a screw driver now undo the nut on the hub , bend the retainer ring back first,undo the nut and the hub will now be free to pull off ,be carefull as it is HEAVY it is best to have help with removing it. on the inside of the hub you will see the seal with a number stamped in it , phone your local truck supply guy with the number and he should be able to tell you if it is a oil or grease seal.some times guys will put in a oil seal even if they use grease which will work but never use a grease seal with oil as it will leak after a very short distance. if f you can get ahold of some fire extinger pyrine wash the brake shoes using rubber gloves, wash them 2or3 times and it will kill any oil or grease on the shoes. when you have the hub of change the seal to the proper one and it should last as long as you have the dream on wheels hope this helps mel 4104 |

Joe the most likly reason the seals are leaking after being replaced 10K ago is that they were not replaced. I had the same thing done and it lasted two years. When they were taken off this time by a different shop they told me the there was a lot of silicone around the seal. t
The shop would not come out and say that they hadn't been replaced.
These seal are hard to find. that's why they used the old seals after replacing the bearings. I have been looking for some for a month now.
i have a '67 4107 which is probably not much different the your 06. |

Your seals are but a phone call away ,
call LUKE at US Coach 1-888-COACH 34.
Because most big trucks are only a few years old , truck stops or truck parts shops have no books and no idea where to obtain almost anything , esp. for a coach.
(Frankly or how to repair them either), bring Da BOOK for all work!
The wheel seals are under $20 and buy TWO sets , one to install, one for the parts box , should it be needed (by yourself or a buddy).
On boats most folks have been burned often enough by BAD parts matches that a spare has a different meaning.
On a boat we install the "spare" part and keep the one that was working as a spare.
With extra nuts or bolts that could be needed when reinstalling the origonal.
Overkill perhaps on a coach, BUT if you have purchased a new,, say,an air compressor gov. it sure is nice to have already DONE the job, and not be at some "mechanics" mercy.
