left wheel until the wrench goes all

Tighten or loosen the diff only in 1/8
turn increments, checking the diff
tightness with each adjustment.
The initial setting should be that the differential action is smooth, but tight
enough so that it takes high effort to rotate the left wheel when the right one
and the spur are held tight. Run the car for approximately one minute. Then
recheck the diff adjustments by again
following the steps above. Your diffs
should be ready.
Hint: The chassis is designed so that
you can very easily adjust the
tightness of the differentials without
taking the body off. Just turn the car
over and adjust the differential from
the bottom of the chassis.
ONE-WAY PULLEY ADJUSTMENT
The one-way pulley allows the front wheels to spin independently from the
rear wheels. Our unique one-way system lets you determine how freely the
front wheels spin. The plastic locknut on the spur layshaft can be fully
tightened to lock the front wheels to the rear (full-time 4WD) or loosened to
let the front free wheel off power (4WD on throttle, RWD off throttle). Or it
can be set somewhere in between to match your driving style.

The main effect of the loosened one-
way is more off-power steering.
However, it should only be used on
high traction surfaces or large tracks
where minimal braking is required;
since only the rear wheels are used
for braking, spins induced by a
locked rear tire are more likely. One
of the benefits of a loosened one-
way pulley is less drive train drag at
maximum speed. This can increase
top speed.

Place the car on the table with the
front end pointing towards you. To
check front diff tightness, hold the
spur gear with your right hand and
hold the left front wheel against the
table with your right forearm, and try
to rotate the front right wheel with
your left hand bbaacckkw
waarrddss. If the front
right wheel rotates too easily, you
need to tighten the front differential.
The diff output shaft on the left side
of the car has a hole in it. Place a
small hex wrench into the hole.
Rotate the front right wheel until the
wrench goes all the way through.
