Off road the Jeep is awesome and on the road it is much more enjoyable!

Thanks for all the input here.
"2 longer lower arms" = caster. I bet this was your problem.

The only thing you need to know/worry about the pitman arm is if you are using a drop pitman arm you need the track bar relocation bracket too, if you are using the stock pitman arm no relo track bar bracket is needed. The main thing is matching stock geometry angles, this is why there are drop arm and relo brackets.

These pieces can lead to bump steer and DW that is why you hear about them all the time.

I guess I put too much confidence on my garage and didn't know which company they would go with!

Knowing all that, I would have go with a 2.5 Teraflex with more parts in it!!

X2^^^ unfortunately there are more companies out there that sell incomplete kits in order to keep their price down. Unsuspected buyers think they are getting a good deal til they have to go back and purchase all the parts separately that should have been in the kit in the first place.

Compare the parts list between the RC 2.5" Spacer kit and the TeraFlex 2.5" BB for instance.

Yea we need to see more pics. A dropped pitman arm is not the best way to go about doing things but should be fine if the track bar is raised to match.

Better way of fixing steering angles is raising the drag link on top the knuckle. This does the same as a dropped pitman but doesn't add stress on the already week sector shaft/steering box.

As you can see in the pic. Either way the track bar needs to be raised or lowered to match angles. Raising being preferred.

You respond to my other thread and since I need a LCA anyway with a 2.5 or 4 lift, I will stay with my 4" lift and enhance it the best I can.

So far, I order LCA and a performance steering stabilizer. I also told my garage to check the slack in the bolt that cause the death wobbles!

SuicideSaints I can't see in the pic of the kit on the jeep but I see in the other pic you took the stock pitman arm off. Did you instal a drop pitman arm? If you did you should be running a drop bracket with the track bar. If you don't have the drop bracket for the track bar take the drop pitman arm off and reinstall the stock one. I guarantee this is your problem with the DW if you don't have that drop bracket. This also might fix your other problem. I would do this before anything else then see how it handles. I can't stress it enough, only use a drop pitman arm with a drop bracket for the track bar. Using one without the other changes the geometry of the steering in a really bad way.

Rogerg I don't have that kit but I too have a 4" lift. I had to ditch the drop pitman arm that came with my kit and reinstall the stocker to correct the steering.Make sure they did an allignment and check your trackbar bolts. FWIW I still use the stock control arms.

First, it is a 2010 Wrangler with a 4" Rough Country lift kit and 35x12.5x17 Fierce Attitude M/T tires.

The problem I have is that the direction is unstable and make it very hard to keep it in straight line at 55 mph, it's even on the merge to be dangerous!!!

I also got a problem that the steering start wobbling like crazy at low speed and force me to stop ...

My question is, am I missing something to make it safer and more enjoyable to drive?
It's posts like this that keep my wheels stock. I dunno man, just go to stock and plasti dip your rims ( black) for the off road look. The stock platform can handle 90% of the off roading most people do. IF you are going to get into mudding or rock crawling- well that's a whole different ball game.

good luck

SilverSport Shakin all over.

kjeeper10 First make sure your front track bar is nice and tight 125 ft lbs.
if there is any movement ie bad bushings/worn holes etc. this is the #1 cause for shakes/dealth wobble.
05-13-2013 06:21 PM
pete731 I order new lower arms and I will pass all the "death wobble" procedure! I'll keep you posted.
05-13-2013 01:33 PM
fljeepleo I know there is more going on than this but also check your tire pressure.
05-13-2013 01:15 PM
kjeeper10 Does look like there's a TB bracket hidden underneath there ?
05-13-2013 01:07 PM
pete731 Which lower control arms should I get, which lenght?

kjeeper10 You have stock control arms.

Control arms position the axle in the wheel well and hold a pinion/caster spec (tilt of the axle)

Lowers like you see in my pic rotate the axle down for a bit more caster.

The only way to really tell where you're at is having the alignment checked.

WatchThis! Some people's/shops idea of an alignment is just seting the toe. Caster is very important also. Dosent hurt to ask them what all and to what #'s they set everything up to, and if they did the work I would make them figure it out.
