VEHICLE DIMENSIONS
The Vehicle Dimensions chart provides the dimen-
sions for each type of Grand Cherokee vehicle.
INTERNATIONAL VEHICLE CONTROL AND DISPLAY
SYMBOLS
The graphic symbols illustrated in the following
chart are used to identify various instrument con-
trols. The symbols correspond to the controls and dis-
plays that are located on the instrument panel.
FASTENER IDENTIFICATION
THREAD IDENTIFICATION
SAE and metric bolt/nut threads are not the same.
The difference is described in the Thread Notation
chart (Fig. 3).
GRADE/CLASS IDENTIFICATION
The SAE bolt strength grades range from grade 2
to grade 8. The higher the grade number, the greater
the bolt strength. Identification is determined by the
line marks on the top of each bolt head. The actual
bolt strength grade corresponds to the number of line
marks plus 2. The most commonly used metric bolt
strength classes are 9.8 and 12.9. The metric
strength class identification number is imprinted on
the head of the bolt. The higher the class number,
the greater the bolt strength. Some metric nuts are
imprinted with a single-digit strength class on the
nut face. Refer to the Fastener Identification and
Fastener Strength Charts.
METRIC SYSTEM
WARNING: USE OF AN INCORRECT FASTENER
MAY RESULT IN COMPONENT DAMAGE OR PER-
SONAL INJURY.
Figure art, specifications and torque references in
this Service Manual are identified in metric and SAE
format.
During any maintenance or repair procedures, it is
important to salvage metric fasteners (nuts, bolts,
etc.) for reassembly. If the fastener is not salvage-
able, a fastener of equivalent specification should be
used.
The metric system is based on quantities of one,
ten, one hundred, one thousand and one million (Fig.
4).
The following chart will assist in converting metric
units to equivalent English and SAE units, or vise
versa.
Refer to the Conversion Chart to convert torque
values listed in metric Newton- meters (N·m). Also,
