Inspection
BALL JOINT AND SWIVEL JOINT
1. Check joints for play. If ball or swivel stud is worn and play
in axial direction is excessive or joint is hard to swing, replace
as a complete unit.
Swinging force (Measure point: Cotter pin hole) ``A'':
Ball joint
15.7 - 147.1 N (1.6 - 15.0 kg, 3.5 - 33.1 lb)
Rotating torque ``B'':
Ball joint
0.5 - 4.9 N´m (5 - 50 kg-cm, 4.3 - 43.4 in-lb)
Swivel joint
1.0 - 5.9 N´m (10 - 60 kg-cm, 8.7 - 52.1 in-lb)
Axial end play ``C'':
Ball joint and swivel joint
0mm(0in)
2. Check condition of dust cover. If it is cracked excessively,
replace as a complete unit.
CAUTION:
Be careful not to apply grease or oil to taper of joint.
IDLER ARM ASSEMBLY
lCheck rubber bushing of idler arm for breakage, wear or
play, and if necessary replace.
lLubricate idler arm assembly with multi-purpose grease, if
necessary.
CROSS ROD AND TIE-ROD
Check tie-rod and cross rod for breakage, bends or cracks, and
replace with a new one if necessary.
FIXING LOCATION
lCheck fixing location (nuts and cotter pins) for looseness,
play or breakage.
lWhen looseness or play is found, check for wear on tapered
portion of joints, gear arm of idler arm.
lWhen reassembling each joint, use new cotter pins.
