(d) Using a brass bar and hammer, install the drive shaft.
NOTICE:
Be careful not to damage the dust cover and oil seal.
HINT:
Whether the inboard joint shaft is in contact with the pinion shaft or not can be known from the sound or feel-
ing when driving.
(e) Check that there is 2 ± 3 mm (0.08 ± 0.12 in.) of play in the axial direction.
(f) Check that the drive shaft cannot be removed by hand.
2. LH drive shaft:
INSTALL LH SHOCK ABSORBER (See page SA±70)

NOTICE:
Be careful not to damage the oil seal, boots and dust seal.
4. CONNECT LOWER SUSPENSION ARM TO LOWER BALL JOINT
(a) Connect the lower suspension arm to the lower ball joint.
(b) Install the nut and a new cotter pin.
If the holes for the cotter pin are not aligned, tighten the nut further up to 60°.
HINT:
Face the hole for the cotter pin forward.
Torque: 140 N´m (1,450 kgf´cm, 103 ft´lbf)
5. INSTALL DRIVE SHAFT LOCK NUT
