Outer Limits 4x4 Board

leave it to pongo. Mate we need to catch up.. you going to clean up day?
I think those photos are almost the same spot..

yeah same spot and illl be at the cleanup. If i can find time this week, ill make the 37's fit the shorty .

drove out there today to help out and within 10 mins i had no clutch fluid.

Hard day for the starter motor.

still rahter my patrol thank your jeep, only cause i dont wanna ride a puch bike again.

nice pics sasjeep, who took those?
only thing is i dont see any doors open

Well I must have opened them cus I was standing next to you when you snaped them there photos.

oh yeh, i forgot

ive just been informed that its the newer cherokees that have had the roofs crumple when opening doors whilst flexed up

if you are refering to KJs, thats the first ive heard of it. i think your informant is extremely dubious. considering that the KJs have apparently a more rigid monocorque body than the XJs. Someone i know rolled one, got out quite fine through the doors and suprised at how well it held up. Having an XJ and a KJ, I havent expereinced any problems with the doors during flex.

not sure of the model but my mate has a 94 and he was doing a lot of searching on the net etc... and came across a few pics and info etc...
just something for people with monocock 4wds to be mindfull off i spose

I know some people with some pretty big xj's and have had them at full travel at the wandin show and stuff and the whole body does flex! The gaps between doors stuff closes up and opens up but they just changed sides each day!

The only roof i have heard of buckling on an xj was one that got really air born and came down on the front !

Don't think it's a huge problem that you would have to think about though.

In the states they have up to 35's and bigger on them and that maybe why because they have alot more flex!

The monocoque will twist but not to the point of not being able to open and close the doors. The worst I've had is with the front right off the ground and the rear left of the ground. I opened the tailgate and it wouldn't shut easily afterwards until some of the weight was back on the wheels. The roof crumpling just sounds ridiculous to me especially since the KJ is more rigid than the XJ which in turn was made more rigid in the facelift it got in 97.

You've also got to remember that every 'frame' will flex. Why do you think rock sliders are only bolted to the frame? It's to allow the chassis and body to flex seperatley, you can watch the gaps open and close in a framed 4WD when worked hard off road particularily if its a ute, the tub can even touch the cab and was complained about recently but I cant remember the 4WD. The XJ is no different except it is torsionally stronger being a monocoque design

Even road cars flex on road, this is why people make suspension strut supports and can improve the handling, they cut down on the frame flexing.

So, what I'm saying is flexing is not limited to the XJ and that it has no adverse effects on it, Jeep did make the for 17 years and sold over 2 million so they must have got something right.

Cheers

I've got a photo somewhere of my Wrangler (which is heavier than the XJ's because of the big ass chassis) all twisted up on a track and my softop is showing signs of distortion as it's stretched tight. Way cool

that would be the "almighty" puslux mate

have a look at one that is used properly and you will see paint missing on the back firewall from the bed rubbing on it or if it has ladder racks it will have dints above the rear screen.

patrols also flex quiet alot in the cab............... enough that every second gq wagon ive ever seen has split the seem behind the back seats

unless the roof realy does cave in i wouldnt say its an issue lol
providing it bends back when you get on flat ground

j-top Heres the other one i found.

Actually Steve I disagree with the above.
1. I personally much prefer body mounted rock sliders as do most of the TJ guys that play on the rocks....way more clearance and protection....Plus if the chassis twists you aren't jamming the rail into the body

Also I dispute the geneic Monocoque being stronger thing.....fo equal weight yes its strong - but IMHo a lot of chassis are stronger that the monocoque ...eg you don't see many monocoque semi's

Yes Xj's twist - but then again there are these things to fix that (details here)

I would like to go up soon. Been busy but hope to back in it after x-mas.
PS. wooders hows the new baby.
