13. CHECK FRONT BEAR ING PRELOAD
Using a torque wrench, measure the preload of the backlash
between the drive pinion and ring gear.
Preload:
New bearing
Reused be«ing
12 - 19 kg<m
(10.4 - 16.5 in.·lb, 1.2 - 1.9 N.m)
6 - 10 kg-<:m
(6.2 - 8.7 in..lb, 0.6 - 1.0 N·ml
(a) If preload is greater than specification, replace the
;' - - - - - -- -- - -- - - "' .. "'"'"' bearing spacer.
SST
(b) If the preload is less than specification, retighten the
nut 130 kg-em (9 ft·lb, 13 N.m) at a time until the
specified preload is reached.
1 f the maximum torque is exceeded while retightening the
nut, replace the bearing spacer and repeat the preload pro-
cedure. Do not back olf the pinion nut to reduce the
preload.
Maximum torque: 2,400 kg-<:m (174 ft·lb, 235 N.m)
14. CHECK RUNOUT OF COMPANION FLANGE
Using a dial indicator. measure the lateral and radial
runout of the companion f'-nge.
If the runout is greater than the maximum, inspect
the
bearings.
Maximum lateral runout: 0.10 mm (0.0039 in.)
Maximum radial runout: 0. 10 mm (0.0039 in.)
