< SERVICE INFORMATION >
FRONT LOWER LINK
• Check the ball joint. Replace the front lower link if any of the follow-
ing conditions exist:
- Ball stud is worn.
- Joint is hard to swing.
- Play in axial direction is excessive.
INSTALLATION
Installation is in the reverse order of removal.
• Tighten the nuts and bolts to specification. Refer to RSU-21, "
Component" .
• Perform the final tightening of the nuts and bolts for the links (rubber bushing) under unladen condition
(unladen condition means that the fuel tank, engine coolant and lubricants are at the full specification, and
the spare tire, jack, hand tools, and mats are in their designated positions) with the tires on level ground.
• Check the wheel alignment. Refer to RSU-23, "
Wheel AlignmentInspection"
Swinging force “A” : Refer to RSU-43, "Ball Joint" .
Turning force “B” : Refer to RSU-43, "
Ball Joint".
Vertical end play “C” : Refer to RSU-43, "
Ball Joint" .

STARTING SYSTEM
• Starter relay [within the intelligent power distribution module engine room (IPDM E/R)]
• Harness for open or short
2.CHECK VOLTAGE DROP ON MAGNETIC SWITCH CIRCUIT
1. Turn the ignition switch OFF.
2. Connect starter motor connector F28.
3. Check voltage between starter motor connector F28 terminal 1
and battery positive terminal using a digital circuit tester.
OK or NG
OK >> Magnetic switch circuit is OK. Further inspection is nec-
essary. Refer to "WORK FLOW" .
NG >> Check harness between the battery and the magnetic
switch for poor continuity.
