Some flex pics of SOA

Just did some quick test on the wood pile in my backyard. There is at least 5" more travel all around but I didn't want to go too far at first. It drives pretty well actually. I took the doors off too! /wwwthreads_images/icons/smile.gif There is a pic showing the Ford 8.8 in the back. Mmmmm, beef ... /wwwthreads_images/icons/smile.gif

Well as I found out the steep angle on the draglink is a bummer. It rotates before the tires move whenever I make an input so there is a major dead spot at the center. It also creates a bad bump steer. Oh well, I new this is going to happen so now I'm considering optinos for a cross over steering setup. I get by with this for the short term, it's time to tie up the loose ends.

Are you sure it is the draglink that is causing the bumpsteer?My SOA has the same setup with no bumpsteer or dead spots.It actually works better than it did w/aal before the SOA.RH

Boy, questions. OK, I'll try to answer all.

Rock-Hog: regarding the bump steer, I had a little before the SOA and that was fixed by removing the track-bar. I think the current problem stems from the combination of steep angle and rotation of the draglink. I can see it twist fore and aft before moving the tires. With the locker in the back it likes to lurch sideways on acceleration as it is and with this loose steering it gets hairy. The S-draglink would at least fix the twisting part eliminating the play caused by it. I think just for kicks I'll try the method suggested to make one out of the rear track-bar with pressed and welded in draglink ends.

Mangler: I'm using 2.5" lift springs (probably old rough-country) and a 4" dropped pitman arm. The onroad ride is fine actually in a straight line. I'm using a swaybar disco and it helps. The total lift is about 10".

Will: I have 6" extended flares with a deep lip and it's kind of decieving on the pictures but there is a ton of room under them. At any rate I'll try my buddy's 36 Swamper's on for size next week to check things out. I'm really fine with the 33s as it is they work well and they force you to drive smartly and pick a good line.

Jamgood96: the shocks are Doetsch Tech from RE, the ones they sell with their SOA kit. I just put the front ones on the stock mounts with the RE upper shock pin-to-eye adapter. For the rear I measured up and down travel relationship to rest position. So if up travel is 5" and down travel is 4" I extend the shock about 60% it's full extention and weld the bottom mounts on like that. If that makes the mount hang down too much you can lift it and use the MORE upper extention bracket to move the upper mount further. This shifts the whole shock position up clearing up things below the axle but retains full shock travel.

Now that's what I call flex! /wwwthreads_images/icons/smile.gif What's the setup?
Btw, I mounted the shocks today and took it for a spin. MUCH BETTER! /wwwthreads_images/icons/smile.gif Duh, I guess you need shocks. Ride is nice and smooth at speed, the squirrelness is gone but the steering is still loose but it's another matter. Fortunately I kept the stock caster so it tracks nice and straight you just need to correct a lot when turning. There is some vibration though that I have to investigate. The front driveshaft is also rubbing against the exhaust pipe so maybe that's it. I wonder if the pipe can be rerouted? I also messed up by forgetting to mark the yokes before removing the front dshaft so that could be also. I'll go through some tests.
Also the rear has walked on me a bit after driving. Initially I set the rear pinion 2 degrees lower than the dshaft but it's now at the same degree as the shaft. I guess the springs must have shifted a bit. Now I have to check how much axle wrap I have and if moves up any more during load I have to shim it since everything is welded down now. /wwwthreads_images/icons/mad.gif
On the positive the 4wheel disc setup rocks! It's not even bled properly but I have much more stopping power. Looks like the e-brake will be fairly easy to fit too using the Ford e-brake cables. I just have to lengthen the threaded rod of the adjuster by 3-4 inches. Overall I like it. Once the bugs are worked out it should be fun. The 4.10 gears work well too. Now I can smoke'm 33s. /wwwthreads_images/icons/smile.gif
Here's a pic of the front dshaft clearance:

I wonder what can be done about it.
This is of the rear driveline angle:

This is of the draglink angle after all is done:

Alfred, do you have any problems with your steering set-up that way? I posted a drawing of doing the same thing months ago, and the conclusion from those on the board that it is not the way to go.

Yeah, I was drafting up the exact same thing and some people here said that it'll flex/rotate fore and aft just the same. Actually, right now with the steep draglink it is the tie rod that rotates fore and aft which is easy to imagine. Just move all angles to the extreme for illustration so you can imagine it. Let's say the draglink is actually vertical (I said extreme) then it will push down or pull up on the tie rod creating a rotating force. Now that I think of it I don't see how Alfred's setup would create the same rotating force since there is no downward push on the tie rod. Anybody agrees?
