2K-8K DEXTER AXLE ALIGNMENT
Axle Alignment – Alignment can be determined by measuring from the center of
the coupler to the center of each end of the axles. The difference should not vary
more than 1/16”. In the case of multiple axles, the axles must also be in line with
each other. The difference between the centers of one axle and end centers of the
other axle must not vary more than 1/8”.
How to measure:
1. Park trailer on level surface.
2. Measure from the center of the coupler to spindle center on each side. To
Simplify the process, plumb lines may be dropped from the coupler and
from the center line of each spindle end. Measurements “A” and “B” can
then be tapped on the floor to eliminate any miss measurement due to
sagging of the tape for long measurements. Compare A and B
measurements. (see Figure 1)
3. Measure the distances “C” and “D” between the front and rear tandem
axles. These distances must be within 1/8” of each other.

4. Measure from the center of the coupler to the front hanger bolt on each
side of trailer.
5. Measure from the front hanger bolt to the equalizer center bolt on each
side of trailer.
6. Measure from the equalizer center bolt to the rear hanger bolt on each
side of trailer. (Measure according to the number of axles on trailer.)
