SOA Major Bumb Steer/Death Wable have no clue what to do.

**mudcrawler90** · 06-13-2009, 01:46 PM

OK heres the problem my dad and I installed 2" shackels and a SOA and have a huge bump steer problem and do not know what to do next.

We have a stabilizer, drom pitman arm, it was alinged yesterday, the sway bar is still hooked up (with discos), the drag link and tie rod are parellel (relocation bracket on the tie rod). Pic shows what my steering looks like now.

Are there any tricks or aftermarket parts we can use to help aleveate this problem because this is almost scarry to drive.

I know there are othe post but most are for TJ's and I couldn't anything for a SOA.

With that much lift you are going to need more than just a dropped pitman arm to correct that steering geometry.

If you have the funds... here is a smoking deal on a hi-steer kit.... http://www.4wheelparts.com/prodDetail.aspx?partNo=TERHSK&jeep-parts=true
especially this weekend, you would get 20 percent off

First go back to whoever it was who informed you to build your SOA like that & give 'em a swift hard kick in the groin.

Let me guess....that piece of metal that's attached to the vacuum disco that you are using to raise the lower end of the tracbar bracket, is a strait piece of metal with two holes drilled in it, and is allowed to "swing" as the tracbar pivots.

Correct?

Joe:
No the track bar extention has a piece welded to the bottem of it that hooks to the disco and stops it from swinging. I got the Jeep with the front done, i had to do the back (sweet deal chech profile for more) whats wrong with it, im new to jeeps.

djrodrigue: I wish i had those kind of funds even with it 20% off.

It looks like your draglink and track bar are parllel. Not the tie rod.

You need to correct that steering like joe said . Order the JB4x4 bracket. Get ride of the track bar and the drop pitmand and go back with Stock and you should be ok.

Harly is right the Track isn't parllel but that aside junk it and get the JB kit you will be very happy.

**mudcrawler90** · 06-13-2009, 06:08 PM

O i see i had the wrong links parellel. That JB4x4 bracket looks good and it far from the tereflex price. but i'm still open for any other ideas (sorry i only make $60 a week).

The steering angle looks ok but I don't know about the bottom bolt for the track bar mount. The bottom bolt looks like it can pivot which negates any function of the track bar. The track bar SHOULD prevent any bump steer.
Death wobble is frequently caused by bad caster angle. With a new SOA, that's where you should first look.

Lose your track bar completely, dont ask just do it!
Buy the JB4x4 bracket and install that (and order the extended tie rod that comes with it if you need it as well)
You need to get the drag link above the leafs at least!

**mudcrawler90** · 06-13-2009, 06:58 PM

I know it looks like the track bar can pivot but we built and tested ourselvs and it will not pivot so that is not the problem.

HARLEYX2 · 06-13-2009, 07:20 PM

What is your caster angle?

**Ironworker709** · 06-13-2009, 07:32 PM

The bump steer is being caused by the trac bar ,it is at an angle downward,when hitting a bump and the axles moves up or down the axle shifts side to side along with the trac bar because it is at an angle and should be parallel with the axle.
Take the trac bar off and see how it handles and rides without it,i KNOW you'll just ditch it then.

The death wobble is either caused by a bad caster angle or ball joints and/or tie rods

**jeepin1995** · 06-13-2009, 07:41 PM

it's not the caster causing the bumpsteer..... i ran my SOA exactly like that (minus track bar) for a year.... bumpsteer like nobody's business..... i ordered the JB4x4 bracket and it's perfect now.

here's what i would do.....
ditch the sway bar AND track bar..... they are overrated. leave the drop pitman arm, and then get the JB4x4 bracket. that's the CHEAPEST option.
by the looks of it, with the JB bracket and the Drop pitman arm, your draglink will be perfect. here is a pic of mine:

Digger 5 · 06-13-2009, 07:42 PM

The track bar was designed to help prevent bumpsteer. It maintains the distance of the spring from the pitman arm under compression. Removal will cause more bumpsteer. This is one of the reasons TJs have trac bars.
