3. DRIVE TRAIN AND CHASSIS2. BRAKE SYSTEM
The brake system is one of the most important safety components. Always follow the directions and
notes given in section BR of the repair manual for the relevant model year when handling brake
system parts.
NOTICE: When repairing the brake master cylinder or TRAC system, bleed the air out of the TRAC
system.
The drive train and chassis are components-that can have great effects on the running performance
and vibration resistance of the vehicle. After installing components in the sections listed in the table
below, perform alignments to ensure correct mounting angles and dimensions. Particularly accurate
repair of the body must also be done to ensure correct alignment.
HINT: Correct procedures and special tools are required for alignment. Always follow the directions
given in the repair manual for the relevant model year during alignment and section DI of this manual.

3. INSTALL RING GEAR ON DIFFERENTIAL CASE
(a) Clean the contact surfaces of the differential case, the
threads of the ring gear and differential case.
(b) Heat the ring gear in boiling water.
(c) Carefully remove the ring gear from the boiling water.
(d) After the moisture on the ring gear has completely evapo-
rated, quickly install the ring gear to the differential case.
HINT:
Align the matchmarks on the ring gear and the differential case.
(e) Temporarily tighten the 2 bolts so that the bolt holes in the
ring gear and differential case are not misaligned.
(f) After the ring gear has cooled sufficiently, install new ring
gear set bolts to which thread lock has been applied.
Thread lock:
Part No. 08833-00100, THREE BOND 1360 K or equiv-
alent.
NOTICE:
New ring gear set bolts should be used in every case.
(g) Torque the set bolts uniformly and a little at a time.
Torque: 64 N´m (650 kgf´cm, 47 ft´lbf)
(h) Tighten the bolts an additional 60 - 90 °.
NOTICE:
Tighten the bolts in diagonally opposite pairs.
4. INSTALL SIDE BEARINGS
(a) 2JZ-GTE M/T:
Using SST and a press, install the side bearings.
SST 09710- 30050, 09726- 36010, 09950- 70010
(09951-07150)
(b) Others:
Using SST and a press, install the side bearings.
SST 09710- 30050, 09950- 60010 (09950- 00560),
