DLukes,

When I got my 2002 aligned, the mechanic got the spec's from a list he had, based on the information he got off of the front axle. Ours was a 34 also and I had him give it more caster to help with the tracking.

I have a 2002 38' and it uses the same front end. I received the specs from WRV and have scanned it into a PDF file.
Check your email!

Gary, Could you send me a copy of the specs please. I took my rig into a truck alignment place last week and they said they couldn't do it because they didn't have any information on the Alpine. Do you have any information on the ride height adjustment?

If at all possible, please post the specs on the forum.

Also, I'm pretty sure Engineer Mike would be interested in them so they can be entered to the library.

Thank you.

Here are the alignment specifications for a 2002 from WRV.
It has been posted that all coaches by WRV use the same specifications. I do not know if this is true


Left Front –Camber, Min -0.1deg, Max 0.7deg
Left Front –Caster, Min 4.2deg, Max 5.2deg
Left Front- Toe, Min 0.02"¯, Max 0,05"¯

Right Front-Camber, Min -0.1deg, Max 0.7deg
Right Front-Caster, Min 4.2deg, Max 5.2deg
Right Front-Toe, Max 0.02"¯, Max 0.05"¯


Front-Cross Camber, Max 0.5deg
Front-Cross Caster, Max 0.5deg
Total Front-Toe, Min 0.03"¯, Max 0.09"¯ (0.06"¯ would be 1/16"¯)


As 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).

Gary,
Based on the information you sent me I have a couple of minor comments on your posting.

Total front toe in is 1/16" (not 1/8").

Also there appears to be a distinction between "ride height" and "spring height". Your data is correct but the manual calls this the "air spring height" not "ride height". The ride height is 3" to 3.5" lower.

Excuse me for being a pedant!

John,

You are correct! I have modified my post to reflect these changes.

I just spent the afternoon under my coach trying to adjust the ride height. After reading this post I have a couple questions. On the front I have a .5 inch metal plate on top of the I beam axle supporting the air spring. Is the correct measurement from the bottom of the frame to the top of this plate since the numbers are for air spring height i.e. as opposed to the top of the I beam axle?

Also, if I have the height adjustment to its limit and it is still too high do I have to change the linkage rod to get the proper height?

Finally, the drivers side body rides lower than the passenger side when the air spring height is the same for both sides. How can this be?
