Once the suspension system checks
out, keep it that way by using proper
driving techniques. That means avoid-
ing sharp turns while driving in first
gear on sand or mud.
If you don’t, debris sprays onto the
track. When enough accumulates, the
track works free of the sprocket. End
connectors break, center guides bend
and you’re broken down.
So, keep your vehicle on its tracks
by taking those turns in second or third
gear. That keeps build-up to a mini-
mum and keeps you on the way to com-
pleting your mission.

t’s slow and time-consuming, but
walking the track is something that
every M88A1 and AVLB driver

thrown track—a far more time-con-
suming prospect.

walk around your vehicle and look
for these potential suspension system
