airbag height gauge

I checked my airbag height today. I was using a tape measure and went into my old toolbox and found my old Aamco 8650 brake shoe gauge I set the distance at 8.5 inches and went to checking worked great. Measured from top of bag plate to bottom of lower bag plate!

With our "new-to-us" coach, I received a piece of plywood cut in nearly the same shape, for the same purpose.  Yours is much fancier!

Another inexpensive "custom tool" is a piece of quarter round with long nails sticking out 8.5" apart.

I keep one on my coach and one in my "inspection tool box".

What's the audience think of an angle finder on the trailing arms? Goal is to have them parallel to the chassis.

It does mean you are able to check how level the frame and the ground are but it might actually be too sensitive of a measurement. That being said if an airbag mount had moved or been repaired it would be the method required.

There are a couple of these on ebay for $9.99. The shipping is the killer...

@Brett,

Like your idea of a stick with 2 nails. Redneck engineering at it's best!

I use a 1/8 inch Dia welding rod bent to the appropriate height and keep it in my tool box.

We use a 12" framing square that we picked up at a thrift store.  Use white paint pen to mark go/no go. This makes it easy for me to use as dear hubby makes adjustments.

I went all fancy and made one out of engraving plastic.  Will post a picture when I go to the coach later this week.
