Finally....Da new rig..

My 2 piece front vibrates like a SOB anything past 30mph in 4wd. Rear 2wd, front drive in neutral, with front hubs locked I don't even notice it. It's the angles i'm working with for the flipped 300 to clear my clutch fork on the 4 speed.

I've debated doing the 1350 axle shaft lately as well. But isn't there still vibes with that at speed? It's an axle shaft not a driveshaft...

My front 2 piece is a 14 bolt pinion with the gear cut off and pressed onto the pillow block. Was an easy choice with a diameter of 1-3/4" no problem finding tube or weld yokes.

With 2 peice driveline it's the angles that cause the vibrations. Saying that if you can keep the angles flat as possible you will have less vibration. I ran axle shaft Driveshafts in my last S&N buggy that were kinda crudely built(but incredibly strong) and I was good to about 45mph then the vibes came on pretty bad. Jantz built me an axle shaft driveshaft in my TJ and I had zero vibration all the way to 70, saying that it was built on a lathe etc so tolerances were very tight. The set Richard built me I have no dough will be vibration free, but again not a 2 piece shaft setup. The only downside is that there may be a slim possibility that my front driveshaft may slightly rub the link on the drivers side at full drop. I really wanted to stay away from using a 2 peice in the front of my buggy as I like to keep things simple and less complicated but sometimes you have to depending on room/pinion location/axle width/etc. My guess is Crash won't but he will have to offset engine to drivers side at bare min, if he wants the engine perfectly centered in the chassis a 2 peice will be probably mandatory.

Clark's running a hp in the front with a 2 piece shaft. You could check out his build thread to see how his angles came out. His car hauls ass, with no vibrations that I'm aware of.

My drivetrain is perfectly centered, i'm running a two peice shaft. My angles are ok, not perfect, i put it where it fit. I have had it up to near 100mph with no vibrations. Shafts were built by Drivelinetech, still holding up.





I couldn't run a 1 peice, it would have hit my lower link before getting full droop when flexing out, and was kissing my starter bolt at full bump.

Thanks for the info/pics clark. Does the pillow block mount on the front x-support of the belly pan?

its mounted to the front edge of the skid, and tied into the upper link mount, straight below the carrier bearing. best i've got.

Thanks for the info clark :awesomework:

What did that setup run ya?

Also is your oil pan skid hard mounted?

I can't remember what i paid for the shaft, but it was worth every penny. Oil pan skid is hard mounted to the engine mounts, and to the skid between the links. I have the TM file for the skid, not sure how it would fit with a 4.3 though.



Sorry to clog your thread with pics, hopefully they help.

Not clogging a thing---I can use every piece of advise or help. Most of the time all I need is a small tidbit of info to figure something out :awesomework:

Driveline Tech also. As fast as you want to go no vibes.

Updates Sucka!

I still prefer build thread on forums---updates coming....:awesomework: Being sick has slowed me down the last few days.

My radiator finally showed up..

I agree. There tends to be more detailed info with the pics. And I hear ya on the sick part, it kicked my ass last week! uke: Hope you feel better

I just realized---they sent me the wrong radiator...

My heater showed up but damn if I didn't realize the vents were separate.. Thats ok those are added to me next batch of parts...

I get the lower part of the cab area started when I got sick with the damn bug...

So I poked along while being sick and got the lower portion of the cab finished up. Its finally starting to show signs of being a real rig,lol.

Next part I spent a few hours and even had the wife come out and help me do some measuring and nailed down some key measurements. So now I have my roof height and door bar height figured out I can keep rolling onward.
