Do you have c.v. at t case?Also what is the driveline angle compared to the rear pinion angle.
No cv, standard two u joint shaft12* angle on the shaft itself 76* at the pinion90* at the TcaseSo that's 14* out of parallel? Right?And yeah I know that's really bad
im struggling to comprehend how 90* can be the number at the TCase. 90* is a right angle.
90* is like an L. Pictures would help.

Ok guy'a finally had time to get these pics uphttp://m.imgur.com/a/XPidPI did move to a more level'd surface and got different measurements but close to the ones beforeRear drive shaft angle reading @ 16*Rear pinion angle reading @ 76*T case angle reading @ 86*Give me some feed back. Also I've been trying to diagnose this for a while, I plan on installing chevy 63's in the rear and I know because of the longer shackles my pinion angle will slightly change but since I took the video of what's going on in the rear end it's got me thinking y'all might have some more input about what I can do
tcase 4*, rear pinion 14*,
Am I reading the angle finder wrong or something?
yes
1980firstgen20r,What do you think is causing your vibrations?When do you feel the vibrations?If the vibrations are caused by out of phase U-joints or driveline angles, it’s usually a fairly straight forward fix.If the vibrations are caused by bad U-joints, or pinion bearings, they usually can be detected by checking for excessive movement.Some axle wrap is normal. Excessive axle wrap may occur on heavy acceleration, braking, and on the trail while applying lots of throttle torque, like rock crawling.https://www.drivelinesnw.com/part-trouble-shooting/vibration-analysis/angle-analysis/measuring-and-correcting-angle-problems/https://www.4wd.com/p/pro-comp-degree-shim-99-200/_/R-DFCW-99-200?utm_source=google&utm_medium=cpc&utm_campaign=shopping&emlprox=out&ppcfon=1&gp=1&scid=scplpEXP99-200&sc_intid=EXP99-200&gclid=EAIaIQobChMInefJv_rO1QIVgYl-Ch18MgRZEAQYBCABEgLnsPD_BwEGnarls.
