Topic: drive shaft help

[pyrosnow911]

hi im putting the marlin 4" lift (5" springs in rear) and dual cases under my 4runner. i was gonna buy a front drive shaft from someone that was for a dual case set up and h said it has 6" of slip, but im also going to be running a hp elocker up front so would that add some extra slip to it and if so would that be enough to keep my shaft from disconnecting when im flexin?

build a square one

in a word  yes

[pyrosnow911 [OP]]

build a square one

but then im stuck going under 25 when im trying to 4h to go to the snow.

[OOPS]

6" is pretty short on slip. I know it would come apart on my rig.

[boggerunner]

ive ran my square front up to 50 with very little vibration

[pyrosnow911 [OP]]

really? you just made sure its perfectly centered?

[boggerunner]

yep, i double checked all my measurments, and it turned out pretty good, im rocking a square one on my crawler too, but the slip is still toyota, the shaft is just square

if you wanna do some 4 hi stuff I would actually steer away from a square shaft. even if you check and double check measurements it is still next to impossible to balance. this is going to turn into more of a debate really but if you already have the shaft, then cut out the tube thats on it and re-weld a piece that is longer so it will fit. you will be much happier with a round over a square

I've got 5" all pro's and I've pulled apart my front driveshaft with 10" of spline so I would say yes you need more slip.  I had it lengthened 2" and haven't had a problem since but 6" is cutting it a little close.  Square driveshafts belong in the Fontucky fab section, I would't recommend it.  Even if your local driveline shop doesn't work with long travel stuff it isn't that hard to go to a farm supply store and get farm implement spline and shaft and just have the shop weld it together and balance it for you.

Thats a pretty strong statement. I'd put my square shaft against a round one, implement, or profeshionally built, any time strength wise! Square round or triangle , it really is a matter of opinion.


Hey Steve  you gonna follow my lines at Flatnasty in a couple weeks?

Yea, it wont be hard to follow! We can hear your square shaft clanking from the other side of the park

We'll see Gittinit.  If I don't it ain't cus I'm worried about a driveshaft breakin.  Maybe if you would bend up a jungle gym on my truck like you got I would.  I just don't like square shafts cus I don't care what anybody says, they can't be balanced.  I hear it from everybody blah blah blah.  I can do 50mph and no vibration blah blah blah.  I just don't believe it.  I never said they are inferior strengthwise.

[79coyotefrg]

maybe some sch 80  tube

if Gittinit or WillyMammoth  builds  it  it will run true

I will find out next week if that was the square tube or the lockright. Wanna place your bets?

[Toymin8r]

OK guys.  We're hijacking this guys thread.  This discussion is better around a campfire after lots of  anyway.

dont make it sound like its the end of the world. i know many people have have run square d lines with no issues. it is a killer way to make a longslip shaft without droppin 300 bucks

[KDXSR5]

I didn't know a long travel driveline is $300... I was thinking more around half that.

[79coyotefrg]

i made my shafts myself  for the cost  of a new cv kit $30 and a box of 6011 rods
