Caster Adjustment - Front

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If caster adjustment is necessary to resolve a vehicle alignment issue, then installing a revised upper control arm(s) is an acceptable method. This procedure should not be routinely performed with all alignments and only after all other possible sources have been inspected and corrected as necessary.

Using alignment equipment and the manufacturer's instructions, measure the caster.

Use the following table and the measurements taken in Step 1 to determine which front upper control arm should be installed.

PART SPECIFICATION TABLE

Part Number	Degree of Change
3084 RH	+ 0.4 degree
3084 RH	- 0.4 degree
3091 LH	+ 0.4 degree
3091 LH	- 0.4 degree

NOTE: The revised upper control arms have the same base part number, but they are identified by the amount of caster they change (for example: + 0.4 degrees or - 0.4 degrees).

Install a revised front upper control arm(s) as necessary. For additional information, refer to INSTALLATION .
Recheck the front caster settings and adjust as necessary.
Check and, if necessary, adjust the front toe. For additional information, refer to TOE ADJUSTMENT - FRONT .
