Lower Arm
Lower ArmCOMPONENTS:
INSPECTION
1. Check the bushing for wear and deterioration.
2. Check the lower arm for bending or breakage.
3. Check the ball joint dust cover for cracks.
4. Check all bolts.
5. Check the lower arm ball joint for rotating torque.
A. If a crack is noted in the dust cover, replace the ball joint assembly.
B. Move the ball joint stud several times in a circular motion.
C. Measure the ball joint rotating torque.
Standard value: 0.4 - 2 Nm (4 - 20 kgf�cm, 0.29 - 1.45 lb-ft)
NOTE: Measure torque using the special tool (09532-11600) and torque wrench at the range of 0.5 - 2 rpm after moving the ball joint stud at degree 3° several times at room temperature.
D. If the rotating torque is below the lower limit of standard value, replace the ball joint assembly.
E. Even if the rotating toque is below the lower limit of the standard value, the ball joint may be reused unless it has drag and excessive play.
INSTALLATION
1. Install the lower arm mounting bolts (A, B).
Tightening torque Nm (kgf�m, lb-ft): 140 - 160 (14 - 16, 101.2 - 115.7)
2. Install the lower arm (B) fork mounting bolt (C) to the fork (A).
Tightening torque Nm (kgf�m, lb-ft): 140 - 160 (14 - 16, 101.2 - 115.7)
CAUTION: Be careful not to damage to the aluminum lower arm.
3. Install the lower arm ball joint mounting bolts (A).
Tightening torque Nm (kgf�m, lb-ft): 100 - 120 (10 - 12, 72.3 - 86.8)
4. Install the wheel and the tire (A) to the front hub (B).
Tightening torque Nm (kgf�m, lb-ft): 90 - 110 (9 - 11, 65.1 - 79.5)
CAUTION: Be careful not to damage the hub bolts (C) when installing the front wheel and tire (A).
REMOVAL
1. Loosen the wheel nuts slightly. Raise the front of the vehicle, and make sure it is securely supported.
2. Remove the front wheel and tire (A) from front hub (B).
CAUTION: Be careful not to damage the hub bolts (C) when removing the front wheel and tire (A).
3. Remove the lower arm ball joint mounting bolts (A).
4. Remove the front lower arm (B) fork mounting bolt (C) from the fork (A).
CAUTION: Be careful not to damage the bolts (A).
CAUTION: Be careful not to damage to the aluminum lower arm.
5. Remove the lower arm mounting bolts (A, B).
REPLACEMENT
1. Using the special tools (09214-32000 & 09216- 211000), remove the bushing from the lower arm.
2. Apply soap solution to the following parts.
^ Outer surface of the bushing.
^ Inner surface of the lower bushing mounting part.
3. Using the special tools (09214-32000 & 09216-21100), install the busing on the lower arm.
CAUTION: Insert bushing in the direction shown in the illustration.
Separation force is over 800 Nm (800 Kgf, 1763 lbf)
