2007 DODGE DURANGO oil change

Axles
Refer to Fluids, Lubricants and Genuine Parts for correct
fluid type.
The manufacturer does not recommend regularly sched-
uled oil changes for axles in vehicles whose operation is
classified as normal truck service.
NOTE:The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Rear Axle
Rear Axle fluid levels should be 1/4(6.4 mm) +/- 1/4“
below the fill hole for 8 1/4, and 9 1/4axles.
Front Axle
Front Axle fluid level should be 1/4” (6.4 mm) below the
level of the fill hole.
Selection of Lubricating Grease
The National Lubricating Grease Institute (NLGI) has
developed a symbol (Certification Mark) to aid the
vehicle owner in the proper selection of grease for chassis
components. This symbol, an example shown below, is
located on the grease container and identifies the appli-
cation and quality of the grease.
There are two groups
identified, those for wheel
bearings (Letter “G”) and
those for chassis (Letter
“L”) lubrication. Perfor-
mance categories within
these groups result in dual
letter designations for
each group. The letter des-
ignations shown in the ex-
ample are the highest
quality level available and when combined as shown can
