5. For 2WD models
 Put matching marks on propeller shaft rebro joint with final
drive companion flange.
CAUTION:
For matching mark, use paint. Never damage propeller
shaft and companion flange.
For AWD models
 Put matching marks on propeller shaft flange yoke with trans- fer companion flange and on rebro joint with final drive com-
panion flange.
CAUTION:
For matching mark, use paint. Never damage propeller
shaft flange yoke, rebro jo int and companion flanges.

REAR PROPELLER SHAFT
 Inspect propeller shaft runout at measuring points. If runoutexceeds specifications, replace propeller shaft assembly. For mea-
suring point, refer to PR-4, "
On-Vehicle Inspection".
 As shown in the figure, while fixing yoke on one side, check axial play of joint. If outside the standard, replace relevant propeller
shaft.
 Check propeller shaft for bend and damage. If damage is detected, replace relevant propeller shaft.
CAUTION:
Never disassemble joints.
 Check center bearing for noise and damage. If noise or damage is
detected, replace center bearing. Refer to PR-11, "
Disassembly
and Assembly of Center Bearing".
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Avoid damaging the rebro joint boot, protect it with a shop towel or equivalent.
 Align matching marks to install propeller shaft to final drive and transfer (AWD models only) companion
flanges, and then tighten to specified torque. Refer to PR-8, "
Component".
 Install center bearing mounting bracket (Upper) with its arrow mark
facing forward.
 Adjust position of mounting bracket sliding back and forth to pre- vent play in thrust direction of center bearing insulator. Install
bracket to vehicle.
 After assembly, perform a driving test to check propeller shaft vibration. If vibration occurred, separate propeller shaft from final
drive. Reinstall companion flange after rotating it by 60, 120, 180,
240, 300 degrees. Then perform driving test and check propeller
shaft vibration again at each point.
 If propeller shaft or final drive has been replaced, connect them as follows: Propeller shaft runout limit : 0.8 mm (0.031 in)

POWER STEERING FLUID
Checking Fluid LevelINFOID:0000000001327709
 Stop engine before performing a fluid level check.
 Ensure that fluid level is between the MAX range and MIN level.
 Because fluid level differs within the HOT range and the COLD range, check it carefully.
CAUTION:
 Do not overfill the Max level.
 Do not reuse any used power steering fluid.
 For recommended fluid, refer to MA-9, "
Fluids and Lubricants".
Checking Fluid LeakageINFOID:0000000001327710
Check the hydraulic piping lines for improper attachment and for
leaks, cracks, damage, loose connections, chafing or deterioration.
1. Run engine until fluid temperature reaches 50 to 80 ° C (122 to
176 °F) in reservoir tank. Keep engine speed idle.
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each “lock” position for five seconds to check fluid leakage.
CAUTION:
Do not hold steering wheel in a locked position for more
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loos en flare nut and then retighten. Do not over tighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to PS-27
.
6. Check steering gear boots for accumulation of fluid indicating a from steering gear.
Air Bleeding Hydraulic SystemINFOID:0000000001327711
Incomplete air bleeding causes the following. When this happens, bleed air again.
 Generation of air bubbles in reservoir tank.
 Generation of clicking noise in oil pump.
 Excessive buzzing in oil pump. NOTE:
When vehicle is stationary or while steering wheel is being turned slowly, some noise may be heard from oil
pump or gear. This noise is normal and does not affect any system.
1. Stop engine, and then turn steering wheel fully to right and left several times. CAUTION:
Do not allow steering fluid reservoir tank to go below the low-level line. Check tank frequently and
add fluid as needed.
2. Run engine at idle speed. Turn steering wheel fully to the right and then fully to the left, and keep for about
three seconds. Then check whether a fluid leakage has occurred.
3. Repeat the 2nd procedure several times at about three seconds intervals. CAUTION:
Do not hold steering wheel in the locked position more than 10 seconds. (There is the possibility
that oil pump may be damaged.)
4. Check generation of air bubbles and cloud in fluid.
5. If air bubbles and the cloud don't fade, stop engine, hold air bleeding until air bubbles and the cloud fade.
Perform the 2nd and the 3rd procedures again. HOT : Fluid temperatures from 50 to 80
°C (122 to
176 °F)
COLD : Fluid temperatures from 0 to 30 °C (32 to 86 °F)
