Toyota Sienna Service Manual: Inspection
1. INSPECT PRELOAD
(a) Using SST(s) and a torque wrench, check the initial torque within the backlash range.
SST 09326-20011 Torque: 0.9 to 1.4 N*m (9 to 14 kgf*cm, 8.0 to 12.4 in.*lbf)
HINT: Use a torque wrench with a fulcrum length of 160 mm (6.30 in.).
(b) Using SST(s) and a torque wrench, check the initial torque while the driven pinion is in contact with the ring gear face.
SST 09326-20011 Torque: Preload +0.15 to 0.30 N*m (+1.6 to 3.1 kgf*cm, +1.3 to 2.7 in.*lbf)
HINT: Use a torque wrench with a fulcrum length of 160 mm (6.30 in.).
2. INSPECT DIFFERENTIAL RING GEAR BACKLASH
(a) Set the dial gauge perpendicular to the tooth face of the ring gear, fix the driven pinion and inspect the backlash while moving the gear.
Backlash: 0.10 to 0.15 mm (0.0039 to 0.0059 in.)
NOTICE: Inspect it at 3 points or more on the gear's periphery.
3. INSPECT TOOTH CONTACT BETWEEN RING GEAR AND DRIVE PINION
(a) Apply red lead primer thinly and uniformly to both faces of the ring gear and rotate several times.
NOTICE: Inspect the tooth contact on the ring gear at 4 places or more.
4. INSPECT RUNOUT OF TRANSFER RING GEAR MOUNTING CASE
(a) Using a dial gauge check the transfer ring gear mounting case runout.
Maximum runout: 0.03 mm (0.0012 in.)

Front Clearance Sonar Sensor RH Circuit
DESCRIPTION
An ultrasonic sensor consists of a sensor portion that transmits and receives
ultrasonic waves and a preamplifier
that amplifies them. The ultrasonic sensor outputs the ultrasonic waves and
sends the reveiced
signals to the clearance warning ECU.
