DIFF ASSEMBLY
Insert the long hub assembly into the short hub assembly, making
sure you line up the bolt in the hub and the bolt threads into the
#3904 locknut.
CHECK ALIGNMENT OF THE HUBS
Tighten the diff with your 5/64" Allen wrench, but not completely.
Screw in the diff bolt a few turns then stop to rotate the diff hubs in
opposite directions.Then screw in the bolt some more. Follow this
procedure to check proper alignment of the parts. The following
note clarfies this.
READ THE FOLLOWING CAREFULLY.
As you tighten the diff bolt, pay close attention to the feeling when
the spring is fully compressed. Do not overtighten the bolt. When
you feel the spring fully compressed, loosen the diff bolt 1/2 turn.
No more, no less. After you have driven the car for one pack,
recheck the diff adjustment as above so that when you feel the
spring fully compressed, loosen the diff bolt 1/2 turn. Never adjust
the diff any other way.
Now assemble the second diff the same way.
