Alignment of the MR IS is not done by bending axles, tubes, cross members or whatever you call them.
I seriously doubt you can get the same precision of alignment the IS affords by bending axles, which is how most trailer axles are aligned.
From MOR/ryde's manual "any alignment shop that can handle full size trailers with multiple axles should be able to handle the job".
MOR/ryde uses a standard Hunter Laser Alignment unit.
How do you think they align them? The only way you can do it is to bend them unless they were bolted on which ususally is only on small trailers.
