98 ride height???

[2TALK42]

On our 98 36', we just replaced both front ride height adjustment valves and still cannot adjust one w/o the other....are they connected? If so, why two valves? I've ran out of ideas...good ones anyway. HELP!!!

I don't know this for sure, as I haven't done a proper trace on it, but my casual observation while staring at other stuff is that there is an air dump valve for the front which tackles air release for both bags. Other than that, I'm not aware of any other connection.

That would indicate some kind of problem w/that valve, which would be obscure to say the least. Can you describe what you have done, and how the rig reacts?

I got it adjusted...had a line hooked up wrong. I got the height of the air bags at 7.5". Will be driving it tomorrow. Don't know what proper height of bags should be....read somewhere 10 3/16...don't think the 98' model bags will go that high. If anyone has some specs on 98' ride height it would help a bunch. Thanks for the response...I really appreciate it.

You will find all the info on the ACA tech. page, Chassis & Brakes. "Neway Suspension Service Manual".
Alpine Coach - Technical Information

When I did mine I measured the wheel arch to ground distance and used that as a check after changing the valves. A lot easier than doing it the "correct" way.

For air spring height, the front and rear suspensions are made by Neway Anchorlok and now owned by Holland.

Front – 10.31"� model AS-120
Rear - 10.5"� model AD-200
Final air spring height must be within ¼ inch

Measurements for rear is taken from bottom of coach frame to bottom of airbag.
Measurement for front is taken from bottom of coach frame to top of axle I beam.
The coach MUST be an unladen condition (flat and level ground).

Thanks for all the info. Adjustments made and the ride is much better.
