34-18 AXLE AND PROPELLER SHAFT - FRONT DIFFERENTIAL ASSEMBLY

CHECKING & ADJUSTMENT

1. Check the driven gear runout
(a). Rotate the driven gear by hand.
(b). Measure the runout on the mounting
surface of the driven gear with a dial
indicator.
Standard : ≤ 0.2mm
If the runout exceeds the limit, replace a
new one. (Refer to "Chapter 34 Axle &
Transmission Shaft - Front Differential
Assembly, Overhaul")

2. Check the engagement mark of the driving
and driven gears
(a). Paint 3-4 teeth at 3 different positions of
the driven gear with red lead powder.
(b). Roate the driven gear clockwise and
counterclockwise by hand for several
rounds.
(c). Check the engagement mark of the driving
and driven gears.
Position: At the center of the driven gear
surface, near the smaller end.
Length: ≥ 60% of the tooth length
Width: ≥ 60% of the tooth width
If the engagement mark is incorrect,
replace the differential bearing and the driving
gear spacers.(Refer to "Chapter 34 Axle &
Transmission Shaft -Front Differential Assembly,
Overhaul" And "Chapter 34 Axle & Transmission
Shaft - Driving Gear,Overhaul")
NOTICE:
It is important to replace the left and right spacers of the differential bearing in pairs.
Meanwhile, the reduced thickness on one side shall equal to the increased thickness on
the other side, in order to ensure the pre-tension of the differential bearing unchanged.
