    There was a pretty steady leak from the rear suspension leveling valve on my 660 from where the connector bracket bolts on.

    Get to the shop and now it's not leaking at all..

    Is this common?

    Would it be advisable to replace it anyway to prevent future leaks?

    Thanks.

    Disconnect it and move lever up and down I’d suspect leak is still there but not in current position.
