LOCK-RIGHT Installations Covered
in This Manual
Capped case differentials, both removable third mem-
ber axles and integral carrier axles. Typical of these are those in
Ford® 9-inch rear axle-equipped vehicles; similar other applica-
tions, such as VW® 091, 002, etc.
Preliminary Steps
The following steps are only a general guide to prelimi-
nary operations used for preparing your vehicle for LOCK-RIGHT
installation. For detailed information, refer to your shop manual.
In general, the preliminary steps include:
a) Blocking the vehicle, putting transmission in neutral;
b) Loosening the wheel lug nuts (tire removal may be
optional; see shop manual);
c) Jacking up the axle; securely resting it on jack stands;
d) Removing the tires (some axles);
e) Disconnecting the brake lines and emergency brake
cables (some axles);
f) Pulling out both axles a few inches.
Differential Case Removal
NOTE: The parts shown in the various figures are typical
and may not exactly depict your particular model.
1. Remove the third member or differential case from
the vehicle as outlined above and described in the shop manual.
Follow all safety precautions.
2. Check to be sure that the gears are in good condition
and that nothing is loose, worn or scored. Rock the ring gear
back and forth to get a “feel” for the backlash and check to see
that it appears to be set up porpperly. If any out-of-spec condi-
tions exist, be sure to correct them before subsequent re-assem-
bly.
3. The differential can be removed and re-assembled
without changing the ring and pinion settings if you are careful.
Mark everything with a center punch! Don’t touch a bolt until
you have done so. we suggest placing the whole assembly up-
right (the same position as show in the vehicle), looking at the
