E: ASSEMBLY
1) Precautions for assembling
(1) Assemble in the reverse order of disassembling.
(2) Check and adjust each part during assembly.
(3) Keep the shims and washers in order, so that they
are not misinstalled.
(4) Thoroughly clean the surfaces on which the shims,
washers and bearings are to be installed.
(5) Apply gear oil when installing the bearings and
thrust washers.
(6) Be careful not to mix up the right and left hand cups
of the bearings.

(7) Replace the oil seal with new one at every disas-
sembly. Apply chassis grease between the lips when
installing the oil seal.
G3M1037
2) Adjusting preload for front and rear bearings
Adjust the bearing preload with spacer and washer
between front and rear bearings. Pinion height adjusting
washer are not affected by this adjustment. The adjustment
must be carried out without oil seal inserted.
(1) Press rear bearing race into differential carrier with
ST1 and ST2.

(2) Insert ST1 into case with pinion height adjusting
washer and rear bearing cone fitted onto it.
CAUTION:
Re-use the used washer if not deformed.
Use a new rear bearing cone.
(3) Then install preload adjusting spacer and washer,
front bearing cone, ST2, companion flange, and washer
and drive pinion nut.
