Detach the center gear

and the center shaft and

replace the small bearing

on the center shaft with

the new metal one.

Tweezers may be helpful

for this step.

Place the center gear back onto the center shaft.

Lightly press and rotate the center gear so the flat

side of the center shaft and the center gear mesh.

Align the front arm shafts with the proper holes,

then attach the front drive unit—with differential

gear installed—to the chassis. Replace the tie rod

and tie rod holder.

Restore the center gear and shaft into their original

positions and rotate center gear so the rear center

gear meshes with the shaft.

Use the lug wrench supplied in your Starter Kit to

detach the lug nuts and wheels.

Loosen and remove the

screw on the knuckle cap

(or disk brake if you have

changed it). Carefully

unlatch the claw on the

knuckle cap and pull out the

wheel shaft along with the

knuckle cap.

Remove the bearings on

both ends of the wheel

shaft. Wipe the grease off

the wheel shaft and install

the metal bearings. The

grease ensures smooth

operation with the original

bearings. When you use the metal bearings, grease

is not necessary.

Replace the bearing on both sides of the differential
gear.

Attach the front drive shafts, as

shown in the illustration.

Loosen the two screws from the tie rod holder and

the screws on the tie rod to remove the tie rod

holder and tie rod. Loosen the two screws from the

front gear case to release the front drive unit and

detach the front gear case cover.
