hub assembly. Using flat-blade pry bar, carefully remove left axle
shaft from differential carrier. DO NOT damage oil seal. On right axle
shaft, remove axle shaft-to-inner shaft flange retaining bolts. Remove
right axle shaft.
CAUTION: Replace circlips on BJ/DOJ splined shaft end.
Installation
1) Install right axle shaft on inner shaft flange. Install
new circlip on DOJ side of left axle shaft. Carefully install left
axle shaft into differential. DO NOT damage oil seal.
2) Reinstall knuckle with front hub assembly. To complete
installation, reverse removal procedure. Install shim and snap ring.

mm). If end play is not within specification, install correct shim.
Page 373 of 1501
into left side axle housing. Install left axle shaft assembly into
axle housing, and tighten nuts to specification. See
TORQUE SPECIFICATIONS.
2) Install right axle shaft assembly into axle housing
without shim or "O" ring. Temporarily tighten nuts in diagonal
sequence to 51.6 INCH lbs. (5.8 N.m) in 2 stages. Measure clearance
between bearing case of right axle and rear axle housing end with
feeler gauge.
3) Select shims equal to sum of measured clearance plus .002-
.008" (.05-.20 mm). Remove right axle shaft, and install selected
shim(s) and "O" ring into right axle housing end. Install right axle
shaft assembly into rear axle housing. Tighten nuts in diagonal
sequence to specification. See TORQUE SPECIFICATIONS.
4) Using dial indicator, check end play of axle shaft. End
play should be .002-.008" (.05-.20 mm). If end play is not within
specification, change shim(s) to obtain correct end play. Reverse
removal procedure to install remaining components. Adjust parking
brake, and bleed brake system.

flange-to-pinion flange position. Remove drive shaft. Remove axle
shafts. See AXLE SHAFT R & I . Support differential carrier with jack.
Remove differential carrier retaining nuts. Remove differential
carrier.

CYLINDER BLOCK
* PLEASE READ THIS FIRST *
NOTE: Always refer to appropriate engine overhaul article in the
ENGINES section for complete overhaul procedures and
specifications for the vehicle being repaired.
BLOCK CLEANING
Only cast cylinder blocks should be hot tank cleaned.
Aluminum cylinder blocks should be cleaned using cold tank method.
Cylinder block is cleaned in order to remove carbon deposits, gasket
residue and water jacket scale. Remove oil galley plugs, freeze plugs
and cam bearings prior to block cleaning.
BLOCK INSPECTION
Visually inspect the block. Check suspected areas for cracks
using the Dye Penetrant inspection method. Block may be checked for
cracks using the Magnaflux method.
Cracks are most commonly found at the bottom of the
cylinders, the main bearing saddles, near expansion plugs and between
the cylinders and water jackets. Inspect lifter bores for damage.
Inspect all head bolt holes for damaged threads. Threads should be
cleaned using tap to ensure proper head bolt torque. Consult machine
shop concerning possible welding and machining (if required).
CYLINDER BORE INSPECTION
Inspect the bore for scuffing or roughness. Cylinder bore
is dimensionally checked for out-of-round and taper using dial bore
gauge. For determining out-of-round, measure cylinder parallel and
perpendicular to the block centerline. Difference in the 2 readings
is the bore out-of-round. Cylinder bore must be checked at top, middle
and bottom of piston travel area.
Bore taper is obtained by measuring bore at the top and
bottom. If wear has exceeded allowable limits, block must be honed
or bored to next available oversize piston dimension.
CYLINDER HONING
Cylinder must be properly honed to allow new piston rings to
properly seat. Cross-hatching at correct angle and depth is critical
to lubrication of cylinder walls and pistons.
A flexible drive hone and power drill are commonly used.
Drive hone must be lubricated during operation. Mix equal parts of
kerosene and SAE 20w engine oil for lubrication.
Apply lubrication to cylinder wall. Operate cylinder hone
from top to bottom of cylinder using even strokes to produce 45 degree
cross-hatch pattern on the cylinder wall. DO NOT allow cylinder hone
to extend below cylinder during operation.
Recheck bore dimension after final honing. Wash cylinder
wall with hot soapy water to remove abrasive particles. Blow dry with
compressed air. Coat cleaned cylinder walls with lubricating oil.
DECK WARPAGE
Check deck for damage or warped head sealing surface. Place
a straightedge across gasket surface of the deck. Using feeler gauge,
measure clearance at center of straightedge. Measure across width and
Page 996 of 1501
DISTRIBUTOR
NOTE: Eclipse, Mirage 1.8L, Montero, Montero Sport 3.0L and 3000GT
DOHC use Distributorless Ignition System (DIS). All other

non-serviceable distributors on which only the rotor and
distributor cap can be changed.
FUEL SYSTEM
* PLEASE READ THIS FIRST *
WARNING: Always relieve fuel pressure before disconnecting any fuel
injection-related component. DO NOT allow fuel to contact

torque arm splines, anchor arm bolt threads and inside of dust cover.
Check for left and right identification marks on torsion bar ends.
Ensure torsion bars are installed in correct locations.
2) Install torsion bar in torque arm, with identification
mark toward front of vehicle and the slit in the anchor collar facing
downward. Align mark on torque arm with mating mark on torsion bar.
When installing a new torsion bar, align White paint spline with index
mark on front anchor arm.
3) Tighten anchor arm bolt adjusting nut to obtain correct
final bolt protrusion. See FINAL ANCHOR ARM BOLT PROTRUSION table.
Final bolt protrusion depends upon curb weight of vehicle. With
vehicle unladen, measure distance from bump stopper bracket to bump
stopper. Distance should be 0.83-0.91" (21-23 mm) on Montero, 0.7" (1\
8
mm) on Montero Sport. If not, adjust anchor bolt nut.
