4. Install a gasket and/or sealant as appropriate.
5. Lift the third member into the axle housing
6. Install and torque the hardware.
Vehicle Final Assembly
Finish the assembly of the remaining parts by reversing
the order of disassembly—in general, the axles/backing plates,
brake lines, emergency brake cables, drive shafts, tires. Note
that in some designs the last 1/8-inch or so of the backing plate
installation is a light press fit and the axle shaft may appear to
be hitting something. Tap the outside end of the axle housing,
check to be sure that they are in their correct positions. Refer to
the shop manual for specific instructions. Your LOCK-RIGHT in-
stallation should now be complete. As a preliminary test, rotate
the tires back and forth (transmission out of gear and drive shaft
free). The drivers should randomly unlock and “click” as the tires
move. Note that the tires will NOT lock together—this easy-un-
locking characteristic is a unique feature of the LOCK-RIGHT and
is perfectly normal.
Tire Diameters
To help assure a long life for your new LOCK-RIGHT, tire
diameters should be as nearly equal as possible. Contrary to
instructions that you may have read elsewhere, 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
the circumference of all the tires, including the spare. Choose
ones that are within about 3/8-inch or less of each other (do not
change from side-to-side if they are radials). If one tire is much
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
sometimes heard during tight turns and provides adequate lubri-
cation when the assembly becomes hot. Also see the section in
the Vehicle Operator’s Manual regarding temperature.
