SUSPENDING THE M9 FOR SUSPENSION SYSTEM CHECKS
While troubleshooting the hydraulic components of the suspension system, the pressure tests are more reliable if
the vehicle is supported by the suspension. If conditions do not permit this, pressure tests should be rechecked to
insure accurate readings. If the suspension must be supported, perform the following procedure:
Place the vehicle on support stands to allow a safe working area under the vehicle while performing procedures
that require working through hull access plate openings. If vehicle support stands are not available, use two long,
parallel timbers, or similar supports, between 12 and 18 in. (30 and 46 cm) high.
