Camber and Caster Adjustment
WARNING: This page is about a different car, the 2004 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
- Using an alignment rack and manufacturer's instructions, measure the caster and camber.
- For additional information, refer to ALIGNMENT SPECIFICATIONS for optimal alignment settings.
- Note any difference between the actual measurements and the specification. This information will be used to select the correct service adjuster.
- Remove the front wheel(s). For additional information, refer to WHEELS AND TIRES .
- Check the type and orientation of the installed adjuster.
- Production adjusters have a round flange, a side tab and the amounts of caster and camber stamped in the top of the adjuster.
- The first number is the amount of caster; the second number is the amount of camber in degrees if the adjuster is installed in the right-hand axle position.
- If the adjuster is in the left-hand axle, the caster number is the opposite sign of the number shown. For example, a positive amount in the right-hand axle is a negative amount in the left axle, and a negative amount in the right-hand is a positive in the left-hand position.
- Service adjusters have a hex flange, no side tab and the adjustment amount of the caster and camber stamped into the top.
- Production adjusters have a round flange, a side tab and the amounts of caster and camber stamped in the top of the adjuster.
- Select a new service adjuster and its orientation in the axle to obtain the optimum caster/camber. Refer to the CAMBER/CASTER SERVICE ADJUSTER . This chart shows the alignment changes that will occur if the vehicle was originally built with 0-degree adjusters
- Note that the caster change or camber change required to obtain the optimum settings must be added to amounts of caster/camber in the old or production adjuster.
- Use this example as a guide. If caster must be reduced 1 degree and camber increased +0.75 degree at the LH wheel, and the existing adjuster has +0.25-degree caster as installed, select the 1-degree service adjuster and orient the slot 225 degrees from the straight-ahead position. In all cases, select the adjuster and orientation that will bring the alignment closest to the optimal settings.
- Remove the pinch bolt and if necessary, use a suitable puller to remove the adjuster from the axle.
- Install the new service adjuster. Orient the slot as noted in Step 5.
- Position the new adjuster as specified in the chart.
- Install the pinch bolt.
- Install the front wheel. For additional information, refer to WHEELS AND TIRES .
- Check the alignment. If not at optimal caster/camber specification, additional adjustment of the rotational orientation of the adjuster is required.
- Once optimal caster/camber has been achieved, reset the toe and clear vision to optimal settings.
CAUTION:
Do not bend axles or radius arms to change alignment.
NOTE:
The assembly plant sometimes builds vehicles with adjusters that are not 0-degree type to control alignment.
