I have had exactly the same experience as Bluevost. I had mine replaced at Mira Loma two years ago and have not been able to lift the front properly since. I discussed this issue with them several times, until they finally convinced me that I was crazy and the bus never lifted any higher than it does now. I guess it is probably too late to do anything about it now, but it is gratifying to know that they were gaslighting me and that I am not actually crazy. I won't back down to their B.S. in in the future. Thanks, guys.
My bags were replaced before Volvo took over, so I can't blame the new owners. But I must say that I have been not just disappointed, but actually disgusted by Prevost service at Mira Loma over the past year. Disgust notwithstanding, my bus is there right now, as there are few other options.
Bryan,
Give me a buzz (949-463-0707). We have a new service option in Southern CA who actually wants our business, and according to Steve Bennett is doing a much better job.

Prevost Jacksonville changed all of ours last year. We have full travel front and rear. Only issue was they twisted an airline going to a tag bag and cut the air to it. It was several weeks before I even noticed and the line does not seem to have been damaged and the bag fills normally now.
I guess every repair and technician is different.
Checked my invoice from Prevost..heres what it says:
2 - #630151 AIR SPRING 12 IN. W/TANK
2 - #630259 AIR SPRING
4 - #630260 AIR SPRING ASSY
Apparently they threw in the air leaks for nothing. Any thoughts? I am unfortunately around 700 miles from the coach so I can't check ride height.
Gran,
This is not a crisis. We should measure it in OKC and compare it to other coaches. If it does not raise to the maximum height Bill Jensen can address that.
Since you have IFS and slides I would like to see how your lift compares to other IFS, with no slides with the 630259 (front air bags)
Granvil,
Those are the same part numbers for the air bags that were used on our bus when we replaced the air bags.
Everything appears to be operating OK, but I didn't actually measure the lift of the old bags before ours were changed.
Prevost has adopted the position that the coach was supplied with the correct air bags, and that if Prevost supplies the correct air bags when replacing them if the coach does not rise to the full design height, then the problem is not with Prevost, but the converter who exceeded the axle weight limits.
I fully support Prevost's position on this. As far back as 1990 or 1991 Prevost made it clear that the axle weight limits were critical and must be observed. They went further to state the responsibility lies with the converter or owners who load the bus so as to exceed limits. There position is important and correct because everything from bearings to brakes to wheels and tires are designed to handle specific loads. Exceeding those limits could cause premature failure, dangerous handling, compromised braking, and problems such as the leveling problems.
However, this discussion which is intended to take place at OKC is not to address coaches that exceed the Prevost limits, but to discuss the loss of utility on the coaches which are not in excess of limits and which have previously operated within the full range of operating heights.
For anyone experiencing problems associated with air bag replacement and compromised suspension travel as a result, please bring whatever data you can to the discussion. For example, make sure you have you axle weights, both the actual and the Prevost limits from the data plate. If you had full travel prior to air bag replacement and know how high the coach would go, please state that and relate that to the new maximum height.
Even if you now have the problem resolved, please bring a list of the part numbers of the air bags involved. This will help all of us learn if this issue is easily resolved.
This issue will not go away unless we can demonstrate that coaches within axle weight limits are now not leveling properly. Bring all the data you can find to support those experiencing the problem, including your model year and serial number so we can see the extent ot the problem.
For this discussion we need to be prepared to present facts. Can someone volunteer to gather data at the rally. Email me or PM to discuss.
Jon,
Good idea. Data collection can be very valuable.
Would there be any benefit to having someone receive the info from various owners and compile the data in an Excel spreadsheet or some other tabular form?
Paul,
Any format that can be distributed would be an excellent idea. I sense we owners are going to be on our own regarding this issue unless we can prove by our data and numbers of affected owners that coaches within the weight limits are not operating as intended and that Prevost needs to address this issue and make it go away.
In the absence of a favorable response from Prevost I would urge we use the information to gather listings of suitable air bags from other sources, including service facilities that will change them for those owners that choose to not do the work themselves.
