The Grove gear axles and axle mounting pads are machined after the gear is bent to shape as I understand it, so the axles after installation should be properly aligned as well as a machinist can do it. So the chances of having properly aligned wheels right out of the box are very good, compared to the "bush" style gear where everything is a weldment.

That said, I agree 100% that the wheel alignment should be checked before any flight or hi speed taxi because an alignment problem can be quite serious. My Grove gear alignment checked out nearly perfect without any shims, but the factory told me they do find the need for 1 shim occasionally, so apparently they do an alignment check on their SLSA's.
