Maybe I am the outcast but I like the front and would move the back forward so you didn't have to do the big comp cut. My preference would be to open up the back but keep the round corners so the body tub keeps it's shape.

Intersting, which reminds me i must dig out your hub nut sockets and send em back

You may want to give your original steering a try before making up your mind on what to do. You should notice that the steering arms on the new axle should be longer then the original TJ ones. Whit the stock steering box you will have more leverage but the steering impute is slower.

Any issues you had while running the 35's will be reduced so you will be able to focus on other problems and get it back on the trails.

Add to that you now have my GC pitman arm drilled for 1 ton tre's
Tis an 1" longer so leverage and full lock are back

Looking like we may be 4 linking the front now to get rid of the panhard rod and clear up some space for the steering bars

4 link front

Are you sure you want to go down this route??

what have we not thought of now

I looked into this with Gasser, basically he told be it does not work on the front application!!

The Mafia has so much flex bumpsteer is a constant battle, 4 link will only compound this.

King CJ has 4 link on the front...... And mog axle weight.....works well with hydro steering.....and a lot of lift...

also works if you cut chassis in front of engine mounts and tube upwards at 45 degrees..... You are now talking buggy Juggy stuff and kerching.....there goes another body part....
Oh and you will deffo need an atv winch to control axle height or lack of when climbing....

so its off to Pirate Hardcore for another night of research for you

How's the work left to do/looming start date of the KOTV working out?

willo · « **Reply #261 on:** June 07, 2012, 09:01:37 PM »

we will be there

No panhard will be a nightmare with conventional steering as said above. The axles centre point will never alter, so everytime your passenger moves the length of the steering arm will change. Meaning flex steer, bump steer and an impossible to correct feel all the time even when going slow.

As nice as 4 link can be on the front it only works with hydro

Although on the front of the auverlander as standard they ran 3 link which should cause the same problem, cant say I have ever driven one to find out.

willo · « **Reply #263 on:** June 08, 2012, 08:03:52 AM »

when I say 4 link, I mean with the upper triangulated, will this also cause the same issues?

Delk · « **Reply #264 on:** June 08, 2012, 08:14:50 AM »

4 link front equals full hydro.

4 link suspension travels straight up and down so conventional steering will creates masses of bump steer.

3 link with a pan hard bar travels in an arc that should be matched to the steering so you don't get bump steer.

willo · « **Reply #265 on:** June 08, 2012, 08:22:17 AM »

Thanks, I also just looked on Pirate and everyone saying the same thing, so pants to that plan, presuming they haven't done it already...

Delk · « **Reply #266 on:** June 08, 2012, 08:54:27 AM »

With a three link front you have to focus on the following to get it to work correctly.

Pan hard and drag links need to be the same length and angles.
There is a highly technical relation between mounting points and body roll.
Lower down on the axle end helps reduce wheel lift when side force is applied.
Flatter angles are better to reduce side to side movement of the axle.

You are not going with a very high lift so this helps.

wildwood · « **Reply #267 on:** June 08, 2012, 11:56:25 AM »

Also with 4 link front you will find that the axle will move to the left and right when articulated...(hence full hydro your only answer)
To get around this if axle far enough forward and diff is clear of stuff like sump and rad then 4 link double triangulated is the way to go.......tis good for rear as well but most just have lower links going straight forward or angled in just a bit.....
Bottom line double triangulated four link is king........

willo · « **Reply #268 on:** June 11, 2012, 06:59:54 PM »

some progress:

Jeep is sitting at full bump, and will go up 3-4" when done, airshox fit inside the arches and will lean forwards, battery's will go in trays level with bottom of new rear bumper, so LHS one fits under the winch brake

hole cut in tub will stay open to stop mud filling up in silly places

and all will be heavily braced so I can use the rear as a middle winch
[attachment=1]

Oh and rear wheels will go out 30mm each side, rear winch housing is future proofed for a twigglepin

willo · « **Reply #269 on:** June 11, 2012, 07:11:59 PM »

And then onto the front, winch will be mounted other way round and low down inline with the new steering box location
