To cv or not to cv (rear drive line)

[zukijames]

so its about time to start thinking about drivelines for my buggy..

here are some numbers.


inches from t case flange to axle flange: 33.5 inches

center of pinion flange from ground: 25 inches

center of t case flange from ground: 29 inches

axle offset: 3.75( thats what i just read i thought it was 4 )


the t case flange is over a inch maybe a little more from center but oh well lets just figure axle flange 4 inches offset from t case flange



so I have about 4 inches vertical difference and 4 inches horizontal


8 inches total..but is that the same as having just 8 inches vertical?


the reason i bring this up is because i spent an hour talking to jon at gaylons drivelines about this and af first he said no problem.. then he said there is no way i wont burn up u joints.. then he said he doesn't think i need a cv because the angles are not very drastic so it shouldn't vibrate..


one thing i can see is with out a cv(double cardigan) that would lessen the angle on the joint at the axle side.. since the cv eats up a few inches of shaft.



anyone running a drive line around that length?

do you have a cv or no cv?

what are your angles like?

does it vibrate?

I'd run one. Yes, it eats up a few inches of shaft, like your mom, , but it also lets you point the pinion at the t-case, so you lose a bunch of angle there anyway. 33" is a decent length though, and that's also a pretty flat driveline if I'm reading your numbers right. Take a hard look at travel and go from there.

i will have lots of travel.. but if i have issues i will limit it..

he just made me feel dumb but he had a hard time realizing my t case was that low..

hes like well how many inches of lift do you have..

well i basically have 0 suspension lift and yeah. i think big truck guys have a hard time visualizing big tires with out big lift. he's thinking this kid has 40 inch tires his truck must be tall!
