Introduction
Welcome to the growing family of LOCK-RIGHT owners!
This manual will help you install your new LOCK-RIGHT automatic
100% full-locking differential. When the installation is complete,
your vehicle will have extreme traction! We trust that you will be
pleased with its performance and thank you for your confidence
in our products.
LOCK-RIGHT installation simply involves disassem-
bling and re-assembling the differential case, replacing a few
parts in the process. These instructions are detailed to the
point that a person who is reasonably familar with automotive
work can install a LOCK-RIGHT into a third member in about
three to four hours; please read them carefully before you start
to be sure that you thoroughly understand them. Do not at-
tempt shortcuts unless you know exactly what you are doing.
These instructions also assume that you have the proper shop
manual for reference to instructions about axle removal, torque
values, settings, clearances, etc. Our manual is a general guide
to operations but does not repeat all the shop manual details.
This manual primarily describes the assembly of the
two- or four-pinion two-piece differential case that has a cap
held on by the ring gear bolts. Some references may be made to
the front axle or to 4x4 operation; if your vehicle is a 4x2, ignore
them. Note that most of the photos are of a Ford® 9-inch assem-
bly; however, the installation of the LOCK-RIGHT itself into the
differential case is the same for VW® differentials and for others
as well.
We suggest that your first installation be done in the
rear axle. This is because the initial weight of the engine over
the front axle is reduced by weight transfer to the rear as your
vehicle climbs a hill, meaning that more and more weight is being
applied to the axle with the locker in it as more traction is need-
ed. If the locker is in the front, tractive weight becomes less as
the hill becomes steeper.
