I had our 2006 F-53 chassis aligned when new and the alignment shop added wedges to adjust alignment. The alignment shop said that wedges allow them to adjust castor without bending the axle. My reading on this web says to get as much positive castor as specs allow to improve driveability.
I've heard this "added wedges" thing before and even heard it from my own alignment shop in South Florida.
The whole idea of adding wedges or bending axles makes little sense to me and I'd love for someone to explain why a chassis manufacturer would design their front suspension in such a way that adding wedges or bending an axle would be necessary, ever.
When I asked the expert alignment guys at Spartan about this, they said that it should never be necessary. They said that other alignment shops simply don't know what they are doing and if they work on both front wheels they should be able to synchronize them so that it isn't necessary.
I tend to think that it makes sense not to need them.
