Is this a type-o or do I just not understand. I am reading the service manual for an '09 FXDL about Chassis and wheel alignment. There is a short link with 2 heim joints that is under the gas tank. One end goes to the engine and the other goes to the top of the frame under the tank. They call this a stabilizer link. This link is adjustable in length. After you adjust the length of the link for engine comfort, they say to "check rear disc brake to ensure that it is parallel to the front brake disc" and "if the rear disc brake is NOT parallel to the front disc, adjust the stabilizer link until they are" This makes no sense to me. How does pulling of pushing the engine against the frame align the rear & front wheels.
