I am putting in a Spring Over Axle kit and add a leaf on my wrangler. The
drive shaft falls out at full extension. My question is:
1.) If I stay with my factory style drive shaft (non CV) why does the
angles in at the transfer case and the rear end have to be the same? I'm
99% certain that I have seen instance where the rear end angle is near zero
and the transfer case angle takes up all the angle. I can pitch the rear
end as much as needed to obtain near 0 angle, because I still need to weld
in my spring perches.

2.) If I can find the money for the CV style does any one have a good
lead on a place that I can get the slip Yoke eliminator kit and shaft?

Thanks for your time,
Tim

 

With the factory driveshaft, the transfer case output shaft angle and rear
axle's pinion shaft angle must be exactly the same, +/1 a degree or so. In
other words, they must be parallel to each other. They must be the same or
they will accelerate in and out of position at different speeds from each
other which is what causes driveshaft vibration which ultimately causes
failed seals and bearings in the drivetrain.

Only when the driveshaft is an aftermarket CV driveshaft can the rear pinion
shaft be raised up... it needs to be pointed directly up and in line with
the driveshaft. Technically, with a leaf-spring vehicle, the rear pinion
angle should be 2-3 degrees under that of the driveshaft to counteract the
effects of axlewrap. :)

Hi Tim,
With the use of Constant Velocity Universal Joints at the Transfer
end of the driveshaft you may aim the pinion directly at the transfer
yoke: http://www.4xshaft.com/driveline101.html Of course, this is the
time upgrade the yoke as your driveshaft won't fit any longer:
http://www.4x4wire.com/jeep/reviews/aasye99/ Replace the shaft don't
weaken yours.
God Bless America, ßill O|||||||O
