Trim Height Specification – Laden Vehicle
Should excessive spring deflection be reported when the
vehicle is laden, then the procedure detailed here, should
be followed.
Checking Procedure
1 Have the vehicle presented in the laden condition
where the spring deflection occurs.
2 Check that all tyre pressures are as spec ified on the
tyre pressure label.

3 With the vehicle on a weighing platform, check
whether the specified Gross Vehicle Weight (GVW)
axle loadings, are achieved. If not, then adjust (using
sand bags if necessary), to achieve the GVW axle
loading specifications shown.
4 After achieving the recommended front and rear axle
loadings, check and note the dimensions, indicated
in the following diagrams.
Important: Ensure that all measurements are taken with
the vehicle on a flat surface.

The links attach to the vehicle with bolts and bushings at their inner pivot points and to the steering knuckle, which is
part of the front wheel spindle, at their outer points.
The knuckle is mounted to the upper and lower links each of which has a ball joint to permit pivoting of the knuckle for
steering operations. The hub is supported in position on the knuckle spindle by means of the two bearings and the rotor
is mounted to the hub.
The front suspension is an independent type utilizing torsion bar springs (4×4, 4×2 (High ride suspension)) and coil
springs (4×2 (Except High ride suspension)). The torsion bar spring has splines on each end. Height control is provided
on the third crossmember. Both the upper and lower links are pressed steel and the torsion bar is supported at the ends
by lower link in front and by height control arm in rear.

Suspension, 4×4 please refer to Section 3C-1 FRONT SUSPENSION (4×
