4.8 Final Air Locker Assembly
c Remove the seal housing, shim pack, and master shim, and clean
all parts of the differential assembly. It is very important to make
sure the seal housing grooves are free from any contaminants (eg:
water, dirt, metal fillings, etc.)
c Generously lubricate the O-rings with oil prior to assembly, then
insert them into the grooves of the seal housing.
NOTE : When assembling the O-rings, be careful not to leave
them twisted when seated in the grooves as this could
cause excessive wear and leakage.
c Lubricate the seal housing running surface on the Air Locker carrier
with oil. Assemble the seal housing by sliding it all of the way onto
the bearing journal with a gentle twisting motion. This will allow the
O-rings to engage gently.
c Assemble the shim pack and master shim.
c Spread the differential housing again (Refer to section 2.6).
c Point the seal housing tube straight out of the housing, hold the
shims and tapered roller bearing cups in place, and insert and hold
the Air Locker into the differential housing.
c Install the bearing caps oriented as they were marked before they
were removed.
c Check to see if the bearing cap on the seal housing side fits over
the tube without fouling.
c Install all bearing cap bolts and tighten with a torque wrench to the
torque specified in your vehicle manufacturer’s service manual.
c Relieve all tension on the housing spreader.
