Replace the RH side by the same procedures as the LH side. 1. INSPECT LOWER BALL JOINT ASSY FRONT LH
(a) Jack up front side of the vehicle.
(b) Check that there is no looseness on the ball joint by shak-ing the lower arm up and down with a force of 294 N (30
kgf, 66 lbf).
2. REMOVE FRONT WHEEL
3.SEPARATE FRONT AXLE HUB LH NUT (See page 30±6) SST 09930±00010

8.SEPARATE FRONT SUSPENSION ARM SUB±ASSY LOWER NO.1 LH (See page 30±22)
9.REMOVE FRONT AXLE ASSY LH (See page 30±22)
10. REMOVE LOWER BALL JOINT ASSY FRONT LH
(a) Remove the cotter pin and nut.
(b) Using SST, remove the lower ball joint assy front LH.
11. INSPECT LOWER BALL JOINT ASSY FRONT LH
(a) As shown in the illustration, flip the ball joint stud back andforth 5 times, before installing the nut.
(b) Using a torque wrench, turn the nut continuously at a rate of 3 ± 5 seconds per 1 turn and take the torque reading
on the 5th turn.
Turning torque:
0.98 ± 4.9 N´m (10 ± 50 kgf´cm, 9 ± 43 in.´lbf)
