Third Member Installation
1. Clean the mating surface of the axle housing and the
mounting surface of the differential carrier.
2. Clean the inside of the axle housing to remove all
foreign material. This step is very important because metal chips
can interfere with the operation of your new LOCK-RIGHT.
3. Remove metal chips from the drain plug if it is mag-
netic.
4. Install a gasket and/or sealant as appropriate.
5. Lift the third member into the axle housing and
shove it into the studs.
6. Install and torque the hardware.
7. Re-install the axle shafts and finish the remaining
vehicle re-assembly steps.
Tire Diameters
To help assure a long life for your new LOCK-RIGHT, tire
diameters should be as nearly equal as possible. DO NOT change
the inflation pressure to vary the rolling radius of the tire! This
practice can be dangerous if one of the tires is under-inflated,
producing excess heat, faster tire wear and more difficult vehi
cle control. The best way to equalize the rotation is to measure
Vehicle Final Assembly
Add gear oil. Note that we suggest using medi-
um-to-heavy oils as recommended by the manufacturer, unless
the vehicle will be used in very cold weather. Thicker oil, such
as 85-140, reduces the “clicking” noise somtimes heard during
tight turns and provides adequate lubrication when the assem-
bly becomes hot. Also see the section in the Vehicle Operator’s
Manual regarding temperature.
Your LOCK-RIGHT installation should now be complete.
As a preliminary test, rotate the tires back and forth (trans-
mission out of gear and driveshaft free). The drivers should
randomly unlock and “click” as the tires move. Note that the
tires will NOT lock together—this easy-unlocking characteristic is
a unique feature of the LOCK-RIGHT and is perfectly normal.
