Tank Straps
During normal operation of the truck, the
DEF tank straps may relax. Inspect the
spring on top of the strap. If more than ½"
(12.7mm) of the spring is exposed, the bolt
will need to be re-torqued between 70 – 80
in-lbs. (7.9 – 9 Nm). This distance (1) is
measured from the washer at the end of
the spring to the edge of the tube at the top
of the straps.

Rear Axle and Suspension
Your vehicle's suspension, by design,
requires a minimal amount of maintenance.
However, suspensions in over-the-road
operations require periodic inspection to
ensure trouble-free performance.
