Axle Alignment
Verify that the forward axle is centered on the trailer; W
1
= W
2
. Check the distance
from the coupler or faceplate center to the forward axle end on both sides, and adjust
the left radius rod if necessary (the right radius rod is of fixed length) so that X
1
is equal
to X
2
. Next check the W and Z distances for the second axle, and then do the same for
the third axle, if so equipped. Try to hold the measurements to within ±

, Section 7.
Axle End Component Disassembly
Whenever the hub equipment on your trailer must be removed for inspection or
maintenance refer to the Meritor Maintenance Manual 14,
Trailer Axles
, beginning with
Section 2.
Hub Inspection
Clean the hub with a commercial solvent for inspection. Check for cracks, elon-
gated holes, evidence of overheating or foreign object damage. The hub is crucial to
safe vehicle operation and any doubt about its condition should be cause for replace-
ment.
Broken or Damaged Studs
Typically when a stud is damaged it is due to under torque (loose capnuts), over
torque, or overloading. Because the studs act together to share the wheel loads, these
parameters must be followed:
1. If one stud is broken, replace the studs on either side of the broken one also.
2. If two or more studs are broken, replace the entire set.
3. A stud with damaged threads should be replaced immediately.
