WASHER
(a) Install the front differential case assembly, side gear, thrust
washer, (Temporarily install) 1.0 mm (0.039 in.) size No.2
thrust washer and No.2 thrust washer to the differential No. 1
case assembly.
HINT: Thrust washer 1.0 mm (0.039 in.) size is for check of back-
lash.
Engage the front differential side gear and pinion gear of
No. 1 case. (b) Using a dial indicator, measure the thrust clearance of front dif-
ferential side gear while holding the No.2
case on the left side.
Standard clearance: 0.14 ± 0.21 mm
(0.006 ± 0.008 in.)
HINT: Turning the side gear a bit, check the maximum value of
thrust clearance.
Referring to the table below, select the thrust washer which. will
ensure that the thrust clearance within specification. Try to select
a washer of the same size. . .
(c) Remove the differential No.2
case.
