In the event that the diff has too tight or too loose gear mesh between the diff spur gear and the pinion drive gear, this is easily resolved by inserting 1 or 2 thin shims behind a
diff outdrive ball-bearing, depending on how much play there is.
GEAR MESH ADJUSTMENT
THE LOCATION OF THE SHIM(S) DEPENDS ON WHETHER YOU ARE TRYING TO CLOSE OR OPEN THE GAP.
To close a wide gap:
add 1 or 2 shims against diff spur gear

Note that to install the shim(s) you must disassemble the diff, install the shim(s), reassemble the diff, and check the gear mesh again.

After assembly the differential should have
a length of 32.15~32.30mm measured
from the ends of the installed ball-bearings.
If differentials are longer, retighten the 4
screws holding the crown gear.
Tight the screws equally
Finish tightening in this order
