ADDITIONAL PARTS USED
You will use your existing side gear thrust washers and cross shaft(s), assuming that they are in excellent
condition. These parts must be replaced if your differential is high-mileage or if wear is evident. If you are
also replacing axle shafts as part of this installation and if your differential has a thrust block, check to see
if it needs to be changed or if end-play adjustment is required.
Note: Thrust Blocks: Toyota Land Cruiser installations do not use the factory thrust block; Jeep AMC-20
differentials do use the thrust block. (If axle shaft end play is involved (AMC-20), the thrust block is required
for correct installation.)
Also note that for all differentials the spider gear thrust washers are NOT used.
Before starting the installation be sure that you have replacement gear oil of the type recommended by
the vehicle manufacturer, and any seals that will need to be replaced. If the vehicle is to be used in hot
weather we recommend the use of 85-140 gear oil, which will provide adequate lubrication and minimize
any sound. Also, synthetics can be used with the Aussie Locker. A dial caliper or a micrometer and set
of feeler gauges are also needed for checking the various existing parts to determine if they
need replacing.
SHOP MANUAL PROCEDURES
As stated above, it is important for you to have your shop manual available and know the R&R proce-
dures that apply to your particular vehicle. The Aussie Locker instructions will describe in detail how to
install your new locker, but they will only mention in general terms about how to remove backing plates
(if even necessary for your vehicle), pull out the axle shafts, remove the differential case, etc. It is up to
the installer to determine the proper method for axle housing and differential disassembly, and be able to
remove the pinion shaft from the differential case so that the locker can be installed.
DIFFERENTIAL DESIGNS
These instructions will assume that the installer has already consulted the shop manual and/or the
internet and various club resources and determined what type of differential design is in his vehicle. There
are two types of axle housing designs in which the Aussie Locker is used. These are: (1) Integral carrier,
such as in the Spicer (Dana) line; and (2) Removable carrier (third member), such as in Toyota Land
Cruisers (although in these vehicles the rear carrier generally is not removed from the vehicle). In turn,
these two types of axles have several differential designs, including: (1) C-Clip axle shaft retention (Ford
8.8, Spicer 35, Land Cruiser with thrust block, etc.); (2) Bearing retainer axle shaft retention (Jeep AMC-
20 with thrust block); (3) Full-floating axles (Land Cruiser fronts, some rears, early Dodges, etc.). The
Aussie Locker design will operate with all these various types of differentials.
