Axles; Selection Of Lubricating Grease - Dodge 2006 Durango Owner's Manual

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 7/8 (22 mm) below the
fill hole for 8 1/4 axles, and 1 1/4 (31 mm) below the fill
hole for 9 1/4 axles.
MAINTAINING YOUR VEHICLE 365
Front Axle
Front Axle fluid level should be 3/4" (20 mm) below the
bottom 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.
