I'm about to order a HD SYE kit and axle shims (or longer shackles) and have a few questions.
- Does the PORC HD SYE come with a new rear output bearing?
- Would a 6 degree shim point the pinion a hair under the TC output? I have around 3-3.5" of lift.
- I read that some early NP231 produced from 1987 – 1990 have the vacuum switch for the front axle disconnect housed in the rear output shaft housing, and that a new SYE housing does not allow for the vacuum switch to be reused. Does anyone have a picture of this so I can make sure that I don't have it?
