Vehicle Final Assembly
When everything is correct, clean the axle housing gas-
ket surface and install the cover using a gasket and/or sealant as
appropriate, and torque the bolts.
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 lubrication when the assem-
bly becomes hot. Also see the section in the Vehicle Operator’s
Manual regarding temperature.
Section 4: 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
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
more worn than the other one, they both should be replaced for
safety reasons.
