Most recent axles have an aluminum tag on them, or stenciling, with the
axle manf, the
axle plant ID (in the case of Dexter for sure) and the order number. Using these numbers, the
axle manf can be queried and a replacement ordered that matches all the specs and variable measurements that are on the original.
A COMPETENT axle shop knows how to reference the Dexter materials and make the proper measurements.
Scamp worked up a particular code to describe the axle to their various suppliers, but unless your supplier deals with
Scamp, they may not even understand the code (that includes a Dexter plant that
Scamp may not deal with. I believe Redneck Trailer Supply can translate the code.
Craig, check with Redneck regarding an axle -- I believe they are in your neck of the woods. BTW, the way you stated it, sounds like you are wanting the full 3,500 lbs -- Is that what
Casita uses? The axle have a range (#9 is somthing like 600-2,200 lbs) and can be "rubbered" at 100 lb intervals during assembly by cutting the rubber to length. I believe the "3,500" axle has a range of 2,300 - 3,500, but I'm not sure. There is an awful lot of tech info in PDF form on the Dexter site.
