Hmmmm interesting. I was just glancing for the numbers, but looking again I definitely see the +- in my book. Adding to the confusion is the insistence on making a word sentence rather just just writing the specs.

service manual reads

Castor:3.5° +- 0.25° positive
Camber: 0.5° +- 0.25° negative

I referred to both, but the second I referred to incorrectly. I was just looking for numbers and ignored the +-, and also assumed that range would be correct because the range on the tsb is so large.

So all that established, you can definitely adjust your caster some, but going off of the original specs and tsb update, it shouldn't really be a big deal.

Def fix the camber though to avoid tire wear.
