Avoid unnecessary removal, installation, disassembly and replacement. • Vehicle components are extremely hot after driving. Be wary of receiving burns from heated parts. • Use grease and oil of Subaru genuine or the equivalent products. Do not mix them of different grades or manufacturers. • Be sure to tighten fasteners including bolts and nuts to the specified torque. • Place shop jacks or rigid racks at the specified points. • Before securing a part on a vise, place cushioning material such as wooden blocks, aluminum plate or cloth between the part and the vise. • If the steering wheel and steering angle sensor are removed, perform the 0 point setting mode for the steering angle sensor. <Ref. to VDC-20, ADJUSTMENT, VDC Control Module and Hydraulic Control Unit (VDCCM&H/U).> (1) Bracket Tightening torque: N·m (kgf-m, ft-lb) (2) Oil pump T1: 16 (1.63, 11.8) (3) O-ring T2: 21 (2.14, 15.5) (4) Joint T3: 33 (3.36, 24.3) T4: 36 (3.67, 26.6) PS-01065 T1 T2 T3 T3 T4 (2) (3) (4) (1)
