REAR SUSPENSION ASSEMBLY
Revision: 2006 January2006 M35/M45
THE ALIGNMENT PROCESS
IMPORTANT:
Use only the alignment specifications listed in this Service Manual.
When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
–The alignment specifications programmed into your machine that operate these indicators may not be cor-
rect.
–This may result in an ERROR.
Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). DO NOT use this “Rolling Compensation”
method.
–Use the “Jacking Compensation Method”. After installing the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
–See Instructions in the alignment machine you're using for more information on this.
CAMBER INSPECTION
Measure camber of both right and left wheels with a suitable alignment gauge.
Adjust in accordance with the following procedures.
If outside the standard value, adjust with adjusting bolt in front
lower link.
NOTE:
After adjusting camber, be sure to check toe-in.
TOE-IN
If toe-in is not within the specification, adjust with adjusting bolt in
rear lower link.
CAUTION:
Be sure to adjust equally on RH and LH side with adjusting bolt.
If toe-in is not still within the specification, inspect and replace any
damaged or worn rear suspension parts.Standard value
Camber : Refer to RSU-18, "
