On a 2013 Cadillac XTS, the caster angle isn’t directly adjustable from the factory — it’s a fixed part of the suspension geometry.
If your caster is out of spec, it usually means something’s bent, worn out, or not sitting right. Could be from accident damage, worn control arm bushings, or a subframe that’s shifted slightly. In some cases, shops use aftermarket alignment kits or offset bushings to tweak the caster a bit, but that’s more of a workaround than a factory-approved adjustment.
If you’re getting a pull or weird steering feel, I’d start by checking:
-
Lower control arms and bushings
-
Strut mounts
-
Subframe alignment
-
And definitely get a printout from a 4-wheel alignment machine
In any case, the service manual should have the caster specs, suspension component diagrams, and steps for inspecting alignment-related parts — super useful if you’re chasing down uneven wear or pull issues.
