Depending on the vehicle type, it can be useful/necessary to use
a camber spreader, as shown below:
In some rare cases, it is required that you unload the wheels
before being able to adjust camber. In these cases, you have to
use the Jack&Hold function coherently, i.e. from the measurement
position, you call Jack&Hold, but only press continue after the
vehicle is raised, and the wheels unloaded, e.g. using a Laserjack
(1 987 009 G02N, special accessory).
If you raise the vehicle without using the Jack&Hold
function, at least the camber values will change, even
with a lift that is levelled in up and down position. Please
do never adjust a car without Jack&Hold, as there may
result values completely out of range after setting it
down and pusing the suspension in
Most of the vehicles of the VAG brands allow adjustment of
camber by unscrewing moreorless the whole axle. Camber is then
equalized right-left, just by remounting the axle slightly different
from before. The wheel centers and thus the symmetry line and
thrust line. Of course, the system does continuously update these
changes and calculates the according toe values.
Whenever the use of special tools is required, like e.g. the camber
adjustment gauge VAG1941 for many VAG vehicles, it will be
shown to you in the adjustment information screen.

Concerning the camber specs, please note that normally all
manufacturers supply camber speccs that are equal left and right.
In reality, there are a lot of vehicles, that will give you a camber
difference of around 20'. Always more negative on the driver's
side. The reason behind this gets clear when the driver takes his
seat. The camber values will be moreorless symmetrical. Real
experts will be able to feel the difference in the drive-straight or
pulling behaviour: Test drive the vehicle on a perfectly even piece
of road, once with and once without a passenger next to the driver.

Adjusting Caster
There are only a few cars where caster is adjustable. Adjustment
is mostly done with excentric screws (e.g. Mercedes),
