My bus is leaning to the left, I recently had an air bag put on the right rear, not the right one for my bus but I believe it was the right hight. now I'm leaning to the left. does my bus have an automatic leveler or is that an aftermarket option? seems the same from front to back on each side. so I wouldn't think it is a bad air bag or the new bag was too tall. | ||

If your bus has stock air suspension, you've got leveling valves integrated into the system. Time to get out DA BOOK and adjust the valves and suspension ride height properly. If someone's installed manual leveling valves, anything goes. . . HTH, RJ PD4106-2784 Fresno CA | ||

Mis-matching air bags side to side is your 1st correction to address. I'm curious as to why you would knowingly install the wrong air bag except as an emergency measure for temporary purposes. While probably not as critical to operation as the fronts, mismatched air bags can cause all kinds of problems. Sort of like putting an F250 leaf spring on a Toyota, or vice versa. | ||

I had to be a few hundred miles away the next day and had an airbag that popped. so they put on what they had that was close to what I had so I could make the next gig. besides they were probably tired of hearing me whine so they just wanted me gone | ||

I can understand the emergency measure but I would now consider a new set of the correct bags across each axle. Seems preferable to adjusting to mis-matches and especially if the other bags are in the condition of the one that popped. Mohawk is a reasonable source for replacements and generally speaking they are not extremely difficult to R&R if u are set up to do it. | ||

I don't have a jack to lift my bus with other wise I could tackle the job. any recomendations on a reasonable priced jack? and remember I full time in my bus so I don't want a big comercial size jack that weighs a ton. I do pull a trailer but don't have a lot of room till I upgrade later this year. | ||

Like what RJ Long said, adjust or repair linkage or valve. About air-bag matching; If it diesel pusher. Mix-match rear suspension bag will not affect the height because air-leveler only apply or remove air to adjusted height. It control L & R side and rear height only. However both L & R front suspension bag should match because it control with one air-leveler. It control front height only. Why? If one front bag has larger square-inch surface area than other, it will lift higher than other. FWIW Sojourn for Christ, Jerry | ||

Harbor Freight has a 20-ton air-over-hydraulic unit that's reasonably priced for occasional use, item #4861-3VGA. www.harborfreight.com HTH. . . | ||

Sojourner has it exactly right. Air bags are not that big a deal to replace and with two jacks and a couple of open end wrenches even I can do it. Raise the air bags to their maximum height and then jack under the frame to get the suspension fully extended. Raise the axle enough to remove the wheel unless you can get access from under the coach. Remove the fittings and the nuts holding the air bag in place, collapse the airbag with a lever or whatever yoou need to get the threaded studs out of the holes and pry or pull the bag out. Just do the reverse to get the new bag in. I had trouble once getting the cap to seat in the top of the air bag so I built a small "cage" so I could air it up before I installed it to seat the cap. When I collapse it for installation or even removal I hold it that way with cheap tie down straps. | ||

If you're going to replace airbags, why not use the ones that do away with the airbeam? The kit for all of them, from MCI, is about $700.... Mohawk's cheaper. | ||

Is that MCI kit at $700 for just one axle ? Does it fit MC-8 | ||

I lost the url for the bag kit... Try a search here for "Now, let's talk airbags on MC8" There's some info there! | ||

Jon W: you have ommitted a MAJOR safety item. NEVER RELY ON A JACK TO KEEP YOU ALIVE. Don't get deep under there with just the jack holding it up - you MUST use something to prop it all up if the jack's potential collapse will kill you. Jackstands, and on a bus that means GOOD ones, are highly recommended. If you don't have those, enough high-quality lumber is a desperate half-measure that I will not recommend unless you are CERTAIN it's enough. A stack of railroad ties MIGHT do it. OK? | ||

Jim, I agree, and assumed everybody understood that. I use hardwood blocking. I will admit to using just hydraulic jacks when I have it suspended by the air bags, so I am placing my faith in the fact that the simultaneous failure of the air bag and the jack is unlikely. Jon | ||

Jon, I personally wouldn't do that. The reason is, if the airbags fail you'll have a sudden rise in stress that could *cause* the jack to fail. You don't really have true redundancy, you've got more like "one and a half". | ||

Not having a pit, I built a set of ramps for putting the bus on when I have to go under it. I parked a D7 on them, so I feel secure w/ them supporting the bus. Then I changed buses and the Neoplan clearances make it difficult to get on them; now I'm planning a concrete pour for 2 ramps, 18' long and 24"wide and 18" rise. Would love to have a 4'deep pit abt. 20' long, but can't overcome the drainage problem. I just don't trust cribbing and jacks. The air/hydraulic jack from HF is a good investment, just have to be careful of where u place it or u may collapse something; always use the jacking pads. | ||

I've mentioned this before on the board...I rented a trencher..dug two paralel ditches about 4 feet apart..about twenty feet long ,filled them with concrete...next day started shoveling out the dirt in the middle...pit has been there for 20 years...has a dirt floor | ||

"... if the airbags fail you'll have a sudden rise in stress that could *cause* the jack to fail." That's why I've been sending all my jacks to therapy twice a week for the past several months. Less likely to have a stressed out jack that way. | ||

Don't do away with the air beam!!! GM designed that beam as an air chamber to soften the ride. The beam holds about 8 times the air in the bellows. The air in the bellows squeezes up into the beam when you hit a bump, softening the ride. The only reason to plate the air beam is if it is so corroded it can't be fixed. Jim-Bob |
