Big Country 6 x 4 and 4 X 2 Update
7
4.2.
The manually operated lift bed now features a
gas charged lift assist cylinder on the 6 X 4 as
well as the 4 X 2. See Figure 4.2.
4.3.
The heat shield will move from the bed to the
muffler tor reduce vibration noise.
4.4.
The dashboard and glove box are now a single
piece instead of two. See Figure 4.4.
4.5.
The engine and transmission support bracket (6
X 4) are solid mounted to the frame. Early ver-
sions (prior to serial number 1A013B000001)
used rubber isolated engine and transmission
support brackets. The solid mountings maintain
more consistent alignment between the trans-
mission and the suspension. Mis-alignment
allows drive-shaft whip, causing vibration under
load, and accelerated wear.

4.6.
The two mounting systems are not interchange-
able. The rear mounting points on the frame are
not drilled and cut to accept the rubber isolator
mounts. The front mounting points have
changed substantially. Inserting rubber isolator
mounts between the frame and the the engine
and transmission support bracket on a Big
Country 6 X 4 that was not meant to have them
will also create clearance issues between the
bed and the intake system. See Figure 4.6.
NOTE:
The solid mounts may allow slightly
higher vibration at idle than the rubber mounts.
4.7.
All of this year’s production will have the smaller
headlights with better optics than last year. This
was a running change during ‘03 model year
production.
