Does your pitman arm clear the spring pack when you turn right and are flexed like that?

[camcruiser13]

yes things are clear and i have no clearance issues, i made sure of all that.

Cam nice writeup. Looks like a good job.

[camcruiser13]

thanks for all the replies,

i loved doing this mod, easy and way worth it. cant wait to hit the trails. ill be putting the top on this weekend, getting chilly around here

[camcruiser13]

so i got the rig out over the weekend, to test all the changes such as

sr
new driveshaft
axle moved foward

and such
all can be found in my write up, ok heres the link and a few pics

Looking good!!! Who done your front driveshaft? Specs? Costs? Thanks.

SWEET.. looks like a nice place to play!

Was that the Mini-Moab trip I missed? I'm missing all the good ones this year. It's ok though I'm going to CM07 and that's final. Just need a cage, antiwrap and locker...oh and fix those damn leaks and I should be all set

Good lookin 40!!

You not getting any vibration from the uneven angles on that driveline? How close is your pitman arm swing to the tierod? I pulled mine forward & decided to bend up some 1 1/2" 1/4" wall DOM for my tierod instead of going hydro which may have been easier. Nothing hits here:

driveshaft is high angle drivelines ( awesome customer service) , it was 279 for retube and 12" slip joint







the pic below is close to full droop and you can see the angle arent to shabby,


its tizzight

my dirveline is perfect, angles are good no vibes whatsoever, nothing hits on the steering. 4x4labs has me covered. i want to go ram assist would be very helpful

Up to what speed? How about with the hubs locked at 60mph? I can't believe that there's "no vibes whatsoever"...

why do you not believe. does your rig vibe that bad?

i rarely drive 60 in 2 wd. but yes at 50-55 no vibrations, jesse does good work.

No it doesn't, but the angles are close to factory. Regardless of how well Jesse does when it comes to making drivelines, the reason I am skeptical is because of the different angles of your driveshaft at the pinion and the 'case.

U-joints are designed to operate in phase with each other, and when one is out of phase you're going to have a lot of vibration by the fact that the driveshaft is moving up and down the splines as the turns. A CV, by keeping the driveshaft in phase (since your pinion u-joint isn't really moving) cancels each other out. Since you don't have a CV at the transfer case, your pinion at the diff is point at the case, your angles are therefore not the same, hence my skepticism when it comes to you saying you have no vibrations.

On the truck I currently drive, no vibrations. But on other trucks that I built because of a differnce in angles, yes I had some bad vibration.

What do you mean you usually don't drive 60mph in 2wd? I'm curious as to whether you have vibration in 4wd, at speed (trail speed is not the point).

Sweet pictures! Looks like you almost went over there. I just finished my spring over and have the same issue of it being really tippy where it wasn't a problem before.

[Ndbbm]

Wait until you feel the ride mine went from rough as hell to buttery smooth, how much lenth did you gain on your shaft, (mine was about 8") & are you going to lenthen the spline and yoke thingie?

why does this keep posting to the wrong thread!!!!

uh who knows,

as far as driving fast my rig is not built for speed
i feel no vibes and am not worried about the quality of the workmanship and parts on my rig, angles are fine no binding which is the bigger issue. i have no need to drive 70 in 4wheel drive or 2wd, if you want to start a debate on wether or not it vibrates in 4x4 come test drive it and judge for yourself.




as far as the write thanks everyone for your feedback. i hope this helps those that are about to enbark on the sr mod journey. feel free to ask for help

i was actually suprised, i thought it would be more tippy than it is, you can notice your higher but not a big deal. i did almost go over. that crack was deeper than i thought, i wish i had a pic before that my fender was kissing the ground on the driver side, talk about clinch

[Ndbbm]

Sorry, thout I was posting to the end of page 1 I hadn't seen page 2 or 3 yet, great write up.

I think for me, therein lies the problem. While there's a difference of opinion in terms of how to build something, (SOA, SR, V8, etc) the advice offered does not always mean that it is the correct way to go (that's not saying you're wrong either). There'll always be people who go against the grain in terms of how something should be done because the application works for them, but suggesting something always, even though collectively the concept doesn't function as well as intended though it might for one specific user, does not mean that all should do it. (Hence, YMMV.)

For instance, most would agree that a CV joint is needed at the case when doing a cut and turn, yet not needed if not cut and turned since your front shaft is long enough and the u joint operating angles are the same.
A more extreme example would be hysteer steering units instead of zlink'd draglinks. Most would agree to stay away from a z style drang link. But that doesn't mean that people still don't use it and swear by it.

For me, your driveshaft defies my experience and theory of how a shaft operates. For your intended use, I'm glad the truck turned out exactly how you wanted it with no issues. Glad to hear there is no vibrations to speak of, and that you're enjoying the hell out of your 40.

Sorry if I seem to be pissing all over your thread, and I will gladly remove the above for statements for your technical contribution and posterity's sake.

no need to remove it, i dont get pissed when someone finds something they are not used to or disagree upon, with out this difference of opinion all fjs would look the same and we would all dress the same etc.. my 40 rides fine (not the way i want it to be yet ie bigger tires, more mods). we are all here to learn and help each other out right
