characteristic as most early 4WD vehicles) because of the locking

feature of the differential. Note: This spinning at high speed on-

road can cause vibration if the drive shaft is unbalanced or if the

vehicle has a lift and the U-joint angles are not matched. If vibra-

tion occurs, carefully check the front end components.

Free-wheeling front hubs cannot be installed in some

vehicles because of the axle assembly design. With a locker in

the front end and the transfer case in the on-road 2WD position,

the only change in vehicle performance will be a slight decrease

in gas mileage and a shorter seal life for the drive pinion flange

and transfer case front output. The life of the drive gears and the

other bearings and seals will remain essentially unchanged.

If the vehicle is to be driven in cold weather, the drag

produced by the thick gear oil will cause a slight pull on the steer-

ing wheel. A solution for this problem is to engage the discon-

nect mechanism so that both axle shafts are spinning, or use a

lighter oil.

Vehicle Performance

General. The first thing that you will notice about the

LOCK-RIGHT installed in the rear axle is that it’s hard to notice.

Unlike some other designs, it is almost inaudible during cornering

and operates with hardly any noise or jerking when driven prop-

erly. In two-wheel driving around town, your vehicle will behave

quite similar to how it did before the LOCK-RIGHT was installed.

Traction. A LOCK-RIGHT installed in the rear axle of your

vehicle will result in much more traction than ever before because

it prevents any wheel spin at all unless both wheels spin. When

either wheel begins to slip, the LOCK-RIGHT immediately trans-

fers more torque to the other one to keep you moving instead

of getting stuck. Thus, with a LOCK-RIGHT, the wheel with the

most traction receives the most power. In a 4x4, this power-dis-

tributing characteristic is even more effective with another one

in the front axle—giving your vehicle the ultimate in traction. It
