The Stovebolt Site Forums The Shop Area Driveline Issues with T5 swap- vibrations, etc᠁

Caster shims should work to pull the axle into alignment. Get one of the magnetic angle finders, they are fairly cheap, and use it to check motor to driveline angle then compare that to driveline to pinion angle. 3 degrees +/- a degree or so on both ends. Having four mounting point may be part of the vibrations and clutch issues, could be not enough flex between the driveline and frame.
