Checking Driveling Vibration & Calculating It.

[Port&PolishMan]

Now this is Relative to the Ground and Chassis is Sitting on Current Stock Ride Height .
This Doesn't allow for Rear Suspension Compressing over the Last 60 Plus Yrs.

OK so the Numbers as Read :

1. Eng. Trans . 3 Degrees Down
2. 1st Drive Shaft Driven - Trig. Out the Angle to be 4.854 Degrees .
3. 2 sec. Drive Shaft Driven Trig. Angle to be 3.7456
4. Rear Diff. 3 Degrees .

Using the Link I Noted a few post back : Gives
Operating Angles of : 1st 1.85
2nd 1.1
3rd .75

Trig. the Carrier Mount _ to be 3/8 inch Shorter the First Driven goes to 4.35
the Second Drive Shaft - would - move to 4.0 Degrees seeing it's almost Twice longer it moves Less .
This would change the Numbers Too : ~

1st Operating 1.35
2nd Operating .35
3rd. Operating Angle 1 Degree .

Please Add You Comments & Corrective Inputs ..
I Might also be able to Lift the Rear Chassis 1/2" _ 5/8 "at least by Adding Spring Assist Shocks . .
Axle to the Carrier bearing being approx 62 inches . .
Which would NOT change the Trig Angle going to Ground - But - Seems like it would change Chassis Position
Which in Turn Should Rotate the Bearing Carrier just a - Nudge - Less on Driven 1 & More on Driven 2
