Topic: TECH: How I built my square driveshaft

Going out to start mine now. Thanks Mini I read both the eHow and here.

ok little confused on how to measure to get the right amount of tubing i will need....
 
anyone explain it better??

[BoG-ToY]

harbor freight carrys an 18" receiver tube (if your going 2") thats really all you need for the ONE side.
for the other side really, what I would do... is compress your front end as much as possible and measure how much tube you would need and cut off an inch or two (just  in case you compress FARTHER then what you did... then lift the truck up, let the axle droop and make sure you would still have plenty of engagement.

Maybe someone else can give you more info, I did mine, it worked great and it was VERY simple.

Build it long, cut it to fit.

1. Measure distance from flange to flange,(A)
2. Measure from flange to cv(B) and flange to u-joint(C)
3. Subtract B and C from A= D
4. Make each piece at least as long as D and weld it up.
5. After it is welded up, put it together.
6. Take dimension A, subtract how much compression you want(E) and cut each piece to make the overall compressed length = A-D

Clear as mud?

am I right in assuming that in 2wd there wouldnt be any vibrations?

[BoG-ToY]

hubs unlocked... tcase in 2wd the shaft is idle..... hubs locked or tcase in 4wd, some vibes... faster you go the worse they are... lol

[NorCalToy]

my shaft is good to 55 or so if im on the throttle. when im coasting its gets bad around 40-45.

[YERF]

Is it just not even worth it to build one with a later model CV?

[BoG-ToY]

grind it out and make it an early model one?

[yjay]

Mine is cv.
Why would this not be preferable?
Minisimp's example is cv. 

[BoG-ToY]

he said late model CV, they were mated to a fixed IFS diff, so although they are limited on droop, you have to remove the tight spots with a rotary file

[yotatough]

I always run 2 standard u joints, never had a real problem without the cv in there

[wakkjobb]

+1; regular U-joints work well so far... CV for rear shaft, yes.

[yotatough]

yeah I run the cv in the rear, my front is good up to 55mph so far.

[BoG-ToY]

sometimes I think its use what you have?

also, you have to change flanges too

[Zane]

can you swap out a 2nd gen front shaft on a first gen? does it bolt up?

This thread helped me in 2014 almost 10 years later. Now that's cool
