Flex steer and spring hanger location prob. - Pirate4x4.Com : 4x4 and Off-Road Forum

Redmist · 07-02-2006, 07:57 PM

As some of you know I stretched my TJ doing the XJ leafs like a few others. This worked out great offroad but I have ran into a problem that I can't figure out.

Some info on my rig.

03 TJ

XJ springs with added main leaf. Almost FLAT at ride.

I used YJ Perches on the frame and built the rear with 2x4x 1/4".
I am using a BDS 4" coil up front with short arms, and ORO steering.
BDS cheep shocks in front and a set of Pro-Comp MX6 adjustables in the
back mounted on a tube from frame rail to rail.

Anti-Rock up front for sway control.

The jeep is great until I hit a spacific section in the road. The Jeep leans into the depression and starts to sway side to side. It is a little freaky at times because it gives a sense that I am out of control. If I try to correct it with the stearing it gets worse.

I have tried letting go of the wheel and it makes things settle out faster. I THINK it is the short arms causing flex stear in the front, but am unsure.

Sorry for the not so hard core tech guys.

Here are some pics of my setup.

If it looks like its the shortarms I will be fabbing a long arm system for the front. But if its something in the rear that I am not seeing then I will change that.

This is my DD.

Thanks in advance guys.

The angle on that drag link isn't helping things any.
(I think your rig is confused, 'cause you've got the flares on backward!)

Yeah the flares are lame looking but It keeps me out of about half the tickets I should be getting.

I thought that the drag link to panhard had no affect on eachother with a crossover setup?

What about spring eye location in the rear? Could the front being lower the rear eye have an affect on the front?

Before you change anything try a rear swaybar.You could fab up some brackets and throw a XJ rear one in just to see.

Also those are stock XJ leafs?...how did you get the Mil wrap?

First rule of SOA, get a traction bar. Second Rule of SOA, get a traction bar.

EDIT: I know that doesn't pertain to your question, but it's just a recommendation.

Check on the traction bar. I have one setup now, but its not in the picture.

I will go out and take some updated pictures for ya. Could my front shocks not be giving me enough control on the sway?

Redmist · 07-03-2006, 07:33 AM

The pictures dont help much, but It's what I have to work with.

The rear packs are stock XJ that I had reconditoned and mil wrapped.

Ok, when I rock my rig side to side by hand the steering wheel moves by itself a good 1/4 of a turn side to side oposite of the movement. something is not correct in the front.

I am going to take it to a friends and have his eyes on the front.
