3 Installing the Air Locker

3.1

Insuring Adequate Oil Drainage

IMPORTANT:

Some Salisbury axles were manufactured with poor oil drainage

between the axle tubes and the differential housing. This can

often result in one of the axle tubes filling up with differential oil

while running. In most cases this will result in a blocked air vent

which will cause the differential housing to pressurize and expel

oil from the axle seals at the wheels or force oil into the air

system of the Air Locker, eventually expelling oil at the solenoid

valve. This is a design flaw which was corrected by most

automakers in the later releases of their axle assemblies. If no

lower drainage point is present in the differential housing then it

is critical that you modify the housing to include one.

 Inspect the differential housing for the presence of adequate

drainage in both axle tubes (refer to Fig.4.).

Figure 4.

 If no drainage slot is present at the left-hand side (refer to Fig.4.) of

the housing at all, then a slot will have to be created as clearance

for the seal housing tube (Refer to Section 3.8 Reinstalling the

Bearing Caps).

 If drainage exists but is inadequate then a slot or hole should be cut

into the housing on the lower side of the tube(s) to allow oil out of

the axle tube area.
