1997 SUBARU LEGACY torque

3) Install rear drive shaft to rear housing and rear differen-
tial spindle.
G4M0453
4) Install rear sensor harness on rear trailing link.
Tightening torque:
32±10 N⋅m (3.3±1.0 kg-m, 24±7 ft-lb)
5) Place a thickness gauge between ABS sensor’s pole
piece and tone wheel’s tooth face. After standard clearance
is obtained over the entire perimeter, tighten ABS sensor
on back plate to specified torque.
ABS sensor standard clearance:
0.7—1.2 mm (0.028—0.047 in)
Tightening torque:
32±10 N⋅m (3.3±1.0 kg-m, 24±7 ft-lb)
CAUTION:
Check the marks on the harness to make sure that no
distortion exists. (RH: white, LH: yellow)
NOTE:
If the clearance is outside specifications, readjust.

SUPPLEMENTAL RESTRAINT SYSTEM“AIRBAG”
Airbag system wiring harness is routed near the center
brake pipe.
CAUTION:

All Airbag system wiring harness and connectors
are colored yellow. Do not use electrical test equip-
ment on these circuit.

Be careful not to damage Airbag system wiring har-
ness when servicing the center brake pipe.
A: REMOVAL AND INSTALLATION
CAUTION:

When removing and installing the brake pipe, make
sure that it is not bent.

After installing the brake pipe and hose, bleed the
air.

After installing the brake hose, make sure that it
does not touch the tire or suspension assembly, etc.
