• If a bearing assembly is accidentally separated when
servicing the brake rotors, it should be replaced.
Rear Wheel Bearings
Clean and repack when brake linings are replaced or

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 the
lubrication of wheel bearings and chassis components.
This symbol (an example shown below) is located on the
grease container and identifies the application and qual-
ity 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
be used for both wheel bearing and chassis lubrication.
Use only those greases that have the NLGI symbol on the
container along with the proper quality level for your
application.
