driveshaft measurements
is there a specific formula or equation to determine proper overall driveshaft length?
in the past i have just said screw it but this time i want to do it as right as possible. i want driveshafts to be the least of my worries.
i am trying to get ready for a ride coming up on the 20th and i am actually ahead of schedule
.
thanks guys.

Here is a decent read Fish, Even has kind of a neat little animation that is interesting. This also has many links too obtain the answers you are looking for.
I probably do not need to remind you about having enough travel for the slip joint. Hate it when a new shaft falls on the floor and messe up the splines cuz it was too short.

what do you mean measurements? as far as what? axle tube to bottom of frame? or completely articulated to completely compressed?
i can sure get some and it could be fun. might have to do some more poser driveway shots while i'm at it!

HaHa....well, I am not exactly sure what you are trying to get out of your driveshaft...
Do you need extended and compressed measurements? Are you trying to get a ride height measurement? Did you recently install a different lift? Why the need to change the length of your DS?

so i cut off one end of each shaft and about 2" last night on both shafts. the hard part is over with. later this week or prolly this weekend i am going to test fit and see. i was just wondering if there was a magical equation to figure up optimum length without pulling out too much of the splines or in danger of punching through my t-case from being too short!

I usually just measure center of u-joint cap at the t-case to center of u-joint cap at axle in the following three positions:
Sitting on level surface
Front Driver tire fully drooped
Front Driver tire fully stuffed
Any good DS shop should be able to make you a DS to fit those numbers.
I thought you were asking the question:
"I just added X amount of lift to my truck...how much longer should the DS be?"
If that were the case, then you could use a bit of geometry (similar triangles) to figure out the length.

lol i wish it were that easy!
i will just drag the bronco out this weekend and do some measuring. i figure our little skidloader should be enough to squat each end enough to get a max squat measurement. and i can pick up each end with the bucket to get a max droop. i know those will be 2 extremes but i think thats how it needs to be.
either that or just pick up each corner with the bucket... that might be more accurate.
