Pinion angle/Shim Axle/CV Shaft install
83 CJ7 w/ 4" lift installed.
Well, I have my CV Shaft back from the driveline place, the yoke installed,
and so I go to put in the CV Shaft. Too Long. The driveline place created
the shaft too long and they measured it. I called and they said no problem,
measure and bring it in and they'll fix it no charge. Anyway, it was kinda
a good thing because I had forgotten I still had the transfercase drop kit
on the jeep when I had it measured the first time. So last weekend when I
installed the yoke I took out the transfercase drop kit spacers. As a
result though I noticed the pinion isn't pointing at the transfercase as
nicely as it was before. The axle is shimmed at 4 degrees so looks like I
need to increase that slope.
Question:
1. With both of the yokes in a vertical orientation I measured from top to
top and bottom to bottom. I got 23 3/8" at the top and 23 3/16" at the
bottom. As I mentioned I have 4 degree shims in there now. Is there a way
I can determine the degree value of the new shims to get the pinion more
pointing to the transfer case? I have an angle finder but cannot find a
good place to lay it for a clear determination. Anyway based on the numbers
above can the increase in slope be determined?
Thanks,
Bill

Re: Pinion angle/Shim Axle/CV Shaft install
You mean the yokes in a horizontal position? I measure center of
U-J to center of U-J. then measure my present shaft with t slip joint in
the centered position the figure the amount have to shorten/lengthen
that tube, and chalk it, with instructions on the tube. Works perfect
ever time.
Forget the angle just aim the pinion at the transfer.

Re: Pinion angle/Shim Axle/CV Shaft install
Hi Bill,
The measurements I have below are with the yokes both in vertical
orientations, not horizontal, with no drive shaft installed. So I measured
from the top to top and bottom to bottom arriving at the numbers below.
Regarding the pinion. How can I determine the shim degree value of the shim
to correct the pinion slope? I guess since the only degree value above the
current 4 degrees I have on there now is 6 degrees (that I can find in a
shop locally), I could just get the 6 degree shims and try them since
they're not that expensive for a pair.
Bill.

Re: Pinion angle/Shim Axle/CV Shaft install
Hi William,
Assuming you were happy with the angle with a 4 degree shim and the one
inch tcase drop, a very rough trig estimate suggests you should try a 6
degree shim without the tcase drop:
x = inv sin((23*sin(4))+1)/23.375) = 6.4 degrees
If you ever need to measure the slope of your pinion you can place the
angle finder on the perpendicular flat surface that the diff cover bolts to.

Assuming you were happy with the angle with a 4 degree shim and the one
inch tcase drop, a very rough trig estimate suggests you should try a 6
degree shim without the tcase drop:
x = inv sin((23*sin(4))+1)/23.375) = 6.4 degrees
If you ever need to measure the slope of your pinion you can place the
angle finder on the perpendicular flat surface that the diff cover bolts to.

Re: Pinion angle/Shim Axle/CV Shaft install
Hi Bill,
Horizontal is like horizon. Use a square on the pinion yoke, if you
can't eye ball it in. Might be best to cut and reposition the perches,
as the thicker wedge may slip off the alignment pins.

Re: Pinion angle/Shim Axle/CV Shaft install
not sure....I think he's letting them hang down and so measuring them that
way...hence vertical and the top/bottom measurements.
