ASSEMBLY
NOTE:
Make sure piston rod on strut is not damaged when attaching components to strut.
1. Install strut attachment (SST) to strut and fix it in a vise.
CAUTION:
When installing strut attachment (SST) to strut, wrap a shop
cloth around strut to protect it from damage.
2. Compress coil spring using a spring compressor (commercial service tool), and install it onto strut. CAUTION:

Face tube side of coil spring downward. Align lower end
to spring rubber seat as shown in the figure.

Be sure spring compressor (commercial service tool) is
securely attached to coil spring. Compress coil spring.
3. Apply soapy water to bound bumper and insert into mounting insulator.
CAUTION:
Do not use machine oil.
4. Install mounting insulator bracket, mounting bearing, bound bumper, spring upper seat, spring upper rubber seat and spring
lower rubber seat.

Installation position of spring upper seat is as shown in the fig-
ure.
5. Fix mounting insulator, then tighten piston rod lock nut with specified torque.
CAUTION:
Be careful not to deform mounting insulator bracket.
6. Gradually release spring compressor (commercial service tool), and remove coil spring.
CAUTION:
Loosen spring compressor while making sure coil spring
attachment position does not move.
7. Remove strut attachment (SST) from strut.

Swing Torque Inspection
NOTE:
Before measurement, move ball joint at least ten times by hand to check for smooth movement.

Hook spring balance at ball stud. Confirm spring balance mea-
surement value is within the specifications when ball stud begins
moving.

If it is outside the specified range, replace transverse link
assembly.
Rotating Torque Inspection

Attach mounting nut to ball stud. Check that rotating torque is
within the specifications with a preload gauge (SST).

If it is outside the specified range, replace transverse link
assembly.
Axial End Play Inspection

Move tip of ball joint in axial direction to check for looseness.

If it is outside the specified range, replace transverse link assembly.
INSTALLATION

Refer to FSU-8, "Removal and Installation" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

After removing/installing or replacing suspension components, check wheel alignment. Refer to FSU-6,
"Wheel Alignment Inspection" .

After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" .

Description NAS00068
This volume explains “Removal, Disassembly, Installation, Inspection and Adjustment” and “Trouble Diag-
noses”.
Te r m sNAS00069

The captions WARNING and CAUTION warn you of steps that must be followed to prevent personal
injury and/or damage to some part of the vehicle.
WARNING indicates the possibility of personal injury if instructions are not followed.
CAUTION indicates the possibility of component damage if instructions are not followed.
BOLD TYPED STATEMENTS except WARNING and CAUTION give you helpful information.
Standard value:Tolerance at inspection and adjustment.
Limit value:The maximum or minimum limit value that should not be exceeded at inspection and adjust-
ment.
UnitsNAS0006A

The UNITS given in this manual are primarily expressed as the SI UNIT (International System of Unit),
and alternatively expressed in the metric system and in the yard/pound system.
Also with regard to tightening torque of bolts and nuts, there are descriptions both about range and about
the standard tightening torque.

ALPHABETICAL INDEX is provided at the end of this manual so that you can rapidly find the item and
page you are searching for.

A QUICK REFERENCE INDEX , a black tab (e.g. ) is provided on the first page. You can quickly find
the first page of each section by matching it to the section's black tab.

THE CONTENTS are listed on the first page of each section.

THE TITLE is indicated on the upper portion of each page and shows the part or system.

THE PAGE NUMBER of each section consists of two or three letters which designate the particular sec-
tion and a number (e.g. “BR-5”).

THE SMALL ILLUSTRATIONS show the important steps such as inspection, use of special tools, knacks
of work and hidden or tricky steps which are not shown in the previous large illustrations.
Assembly, inspection and adjustment procedures for the complicated units such as the automatic tran-
saxle or transmission, etc. are presented in a step-by-step format where necessary. Outer Socket Lock Nut : 59 - 78 N·m (6.0 - 8.0 kg-m, 43 - 58 ft-lb)
