42-39


Rear axle, servicing (all-wheel-
drive vehicles) WARNING!
CAUTION!
Do not attempt to move a vehicle from which
the drive axle has been removed. Otherwise
wheel bearing damage will result. If the vehicle
must be moved, install an outer CV joint in
place of the drive axle.
Do not attempt to weld or straighten the load-
bearing or wheel locating components of the
rear suspension.
Do not re-use fasteners that are worn or
deformed in normal use.
Some fasteners are designed to be used only
once, and are unreliable and may fail if used
a second time. This includes, but is not
limited to, nuts, bolts, washers, circlips and
cotter pins. Always follow recommendations
in this manual-replace these fasteners with
new parts where indicated, and any other
time it is deemed necessary by inspection.

Information on weight codes (code number)

From model year 1998 , spring/shock
assemblies will be classified according to weight
codes (code number) so that suspension
components can be matched easily. The spring/shock assembly installed in the
vehicle is indicated by the weight code on the
vehicle data label.

Example of vehicle data label
The vehicle data label is located in the spare wheel well and in the vehicle
Maintenance booklet.
The weight codes can be used to identify the correct spring/shock
assemblies on the parts catalog microfiche. A - Weight code for front suspension
B - Weight code for rear suspension
