that the axle has a very small amount of side to side play in it. The thickness

1 - Locate the tree of ride height inserts [81]. Select an insert that will work best with your
tire size
. Save the
left over inserts as you will use these to adjust rear ride height as the tires wear.
2 - Insert a 1/4” x 3/8” [82] Flanged Bearing into each of the ride height spacers.
3 - Now insert the ride height spacers into the rear pod plates with the bearings up.
4 - Slide the rear axle [83] through two 1/4” shims [84] and into the 2 rear pod bearings.
5 - On the protruding axle, slip two more 1/4” shims over the axle. Then slip the hub [85] on
as shown in the picture.
(example - the #2 spacers will give you about 5mm of ride height with 2.20” tires)

NSTALL AND GREASE THE DIFF BALLS
Pop the 1/8” diff balls [87] into each of the outer ring of holes in the
diff gear [88]. The balls snap into the socket. Place a small dab of
silicone diff grease [89] on each ball. Use very little!
*(Holding the car on it’s side, with the rear axle pointing upright will
ease assembly of the diff.) Place 1 diff ring [90], and then a 1/4” x
3/8” plain bearing [91] over the end of the axle. Align the diff ring so
that it notches into the axle flange. Place the assembled gear with
the greased diff balls over the axle and push it down over the plain
bearing. Next, insert the other plain bearing into the back of the diff
hub [92]. Then, align the second diff ring with the notch on the back
of the diff hub. *(place a small dab of the diff grease on the hub first
to hold the ring in place.)* Now, slide the hub, bearing, & diff ring
down over the axle. Next, slide a flanged bearing [82] over the axle
and into the front of the diff hub.

The diff spacer [93] has a small machined
lip on one side, point that lip toward the
bearing. Now, place the spring washer [94]
so that the cone points away from the gear.
The outside of the washer should be
against the diff spacer, and the inside of the
washer should be against the diff nut [95],
which now goes on last. *Be sure the 2 “D”
rings have settled into their notches. Just
snug the nut so the parts stay together on
the diff axle. Correct diff tension needs to
be set with tires on the car. We will do this
later.

to not pinch the bearings.
