*** PLEASE READ THIS FIRST ***
NOTE: Information in this article only applies to models with
independent rear suspension. For other models, see
appropriate DRIVE AXLE - INTEGRAL HOUSING
article.
DESCRIPTION & OPERATION
Axle shafts transfer power from differential or transaxle to
driving wheels. All axle shafts consist of a shaft and flexible
Constant Velocity (CV) joint at each end. Inner CV joint is bolted or
splined to differential or transaxle. Outer CV joint is splined to hub
assembly and secured by axle shaft nut.
Inner CV joint is a plunging tripod joint. The plunging
action allows for axle shaft length change as suspension moves up and
down.
Inner and outer CV joints are enclosed by a CV joint boot.
Boot maintains lubrication in joint and prevents contamination of CV
lubricant. Boots must be replaced if leaking or cracked. Inner CV
joint can be repaired without replacing assembly; outer CV joint must
be replaced as an assembly.
TROUBLE SHOOTING
NOTE: See TROUBLE SHOOTING - BASIC PROCEDURES article
in the GENERAL INFORMATION section.
REMOVAL, DISASSEMBLY, REASSEMBLY & INSTALLATION
REAR AXLE SHAFT
Removal

disc brake hub, remove cotter pin and lock nut. See Fig. 1. Place
match marks on inboard axle shaft flange and differential flange.
Remove nuts (4) securing axle shafts to differential flange.
Disconnect axle shaft from differential. Slide axle shaft out of wheel
hub and remove from vehicle.

Inspection
Ensure no play exists in inboard and outboard joints. Inboard
joint must slide smoothly in thrust direction and be free from
excessive play in radial direction. Check for torn or damaged boots.
Disassembly
1) Remove inboard joint boot clamps and slide boot off of
inboard joint tulip. See Fig. 1. Paint match marks on inboard joint
tulip and axle shaft. Remove inboard tulip from axle shaft.
CAUTION: When removing tripod joint, DO NOT use brass drift on
tripod roller.
2) Remove snap ring from tripod spider. Paint matching marks
on tripod spider and axle shaft. Drive tripod spider from axle shaft
using hammer and brass drift. Remove inboard boot. Remove outboard
boot clamps and slide boot from joint.
NOTE: Toyota does not recommend overhaul of outboard CV joint
assembly.
Reassembly
1) Wrap axle shaft splines with vinyl tape. Temporarily
install new boots and clamps. Inboard and outboard boots are not the
same design. Outboard joint boot and clamp are smaller than inboard
boot and clamp. See Fig. 2.

CAUTION: When installing tripod joint, DO NOT use brass drift on
tripod roller.
2) Aligning matching marks made at disassembly, install
tripod spider onto axle shaft. Install snap ring. Pack inboard joint
tulip with CV joint grease supplied in overhaul kit. Grease capacity
is 6.3 ozs. (180 g). Slide tulip over onto axle shaft. Install inboard
boot, but DO NOT tighten clamps at this time.
3) Pack outboard joint with CV joint grease supplied in
overhaul kit. Grease capacity is 4.2 ozs. (120 g). Slide boot over
joint; DO NOT tighten clamps. Ensure boots are not stretched or
compressed with shaft at standard length. Standard length for both
axles is 18.07" (459.1 mm). See Fig. 3. Tighten boot clamps.

REAR AXLE HUB & CARRIER
Removal
1) Raise and support vehicle. Remove rear wheel. Remove
cotter pin and lock nut cap. Remove disc brake caliper without
disconnecting hydraulic line. Place matching marks on rotor and axle
hub. See Fig. 4. Remove rotor.
2) Check hub bearing end play and axle hub runout. See
Fig. 5. If bearing end play is greater than .002" (.05 mm), replace
bearing. If hub runout is greater than .003" (.07 mm), replace hub.
Apply parking brake and remove bearing lock nut. Release parking
brake. Remove parking brake assembly and cable. Remove rear speed
sensor (if equipped).

axle hub. Remove backing plate from carrier. Remove inner and outer
oil seal from carrier. Remove retaining snap ring from carrier. Press
bearing from axle carrier. To reassemble axle carrier, reverse
disassembly procedure.
Installation
To install axle carrier, reverse removal procedure. Tighten 2
axle carrier-to-strut nuts to 188 ft. lbs. (255 N.m). After attaching
suspension strut rod and lower suspension arms, DO NOT final tighten
bolts. Reinstall wheels, lower vehicle and bounce several times to
