    Hey Gil,

    Sorry for the delayed response. I lifted my tag axle before I turned off the coach and it seems to be holding? it has stayed up for a day now.

    Thanks Pablo.

    Pablo before u raised the tag did u go to level low and manually raise the rear of the bus up first?
    . If not your results were potentially incorrect.

    Without first going all up rear and u dump the tag the back squatts so much it may alter test results.

    If after u try my suggestion and the lean is in fact gone away........... that means your lean is either.

    The 2 position spool valve between the drive bags and the tag bag.

    OR
    The tag bag

    OR

    The tag bag ping tank ( football)

    OR
    A fitting or line associated with those components.

    I did not do that. But after a day or two it did leak down. I read your explanation of the fix and I do not think I would be able to correct it myself.

    It looks like I'm headed to the shop.

    Thanks for the information.

    You're close to the Prevost shop. I'd use them and make sure you are assigned a good air system tech. It shouldn't be too hard to troubleshoot based on what you've said.
