Front Disc Brake
everything from the knuckle out, including the birfield
and inner axle. You will not use the inner axle, but
you must separate it from the birfield. To do this,
you can put the inner axle in a large vise, and with
a block of wood and a large hammer or mallet, drive
the birfield off the axle. (wear safety goggles!)
you won't be using the Cruiser parts anymore, an easy
way to remove the knuckle assembly is to remove the
locking clip on the outer birfield, just inside the
locking hub, then remove the bolts on the back of
the steering knuckle. These bolts hold the gasket
seal on the knuckle. Now remove the steering arm from
the knuckle. You may need to pound the sides of the
steering arms to get the acorn nuts to pop out. Now
the whole assembly will slide right off, and you don't
have a mess of greasy parts to deal with!
pull the Cruiser birfield and inner axle out, and
perform the same procedure as separating the pickup
axles. Take the the donor birfields from a 79-85 toyota
4x4 truck and attach them to the cruiser axles. They
will just slide right together. If you happen to get
the Cruiser and mini truck inner axles mixed up, don't
worry. The mini truck ones are about one inch longer
than the Cruiser inners that you will be using.
you put the 79-85 toyota 4x4 truck birfield into
the Cruiser axle housing, you must do a little bit of
grinding on the lower inside of the knuckle ball for
the birfield to fit. Approximately 1/16" should be shaved
off in order to squeeze the bigger, stronger mini truck
'fields in. You should not have to grind the top part
of the housing.
you get the birfield and inner axle to slide into the
housing, you can start putting the mini truck parts onto
the housing. This should be done part by part, so that
you can inspect and repack bearings, and properly torque
every bolt. Don't forget to refill the knuckle chock full
Cruiser is a '68 or newer, then the brake lines will
fit right up. If it is older, then the threads are different,
and you will need to change them. Also, if it is older
than 71, then you won't have a brake booster and more
than likely want one. I recommend the booster and master
cylinder from the mini truck you got the front end parts
from. The booster and master cylinder from a later model
Cruiser will work as well. Some firewall modifications
will most likely be necessary for the new hardware.
you put the driver side steering arm on the knuckle, you
will need to cut it. Cut approximately where the white
line is marked in the picture.
both sides are complete, you can put the tie rod on. You
must use the mini truck tie rod because the ends are larger
than the Cruiser ends.
the brake system, and check everything over. Make sure
you fill your front diff back up with gear oil!
