What size/brand lift are you running and how does your Rubicon Drive?

Yours like this?

Since, going to JKS bar and stock pitman arm all those problems are gone. Most forum “experts” will say go with Currie ($309) bar because it has better clearance over the D44. This is true but if you’ve extended bump stops in front like me than the JKS bar ($185) will never contact the diff.

RC track bar with bracket, notice the bent tie rod. The bend is directly below the track bar bracket.

Here's the JKS track bar with much better clearance
Ok that makes sense.

Im running a 5.5 in Rubicon Express Long Arm kit with a 1 in body lift. I have 35 in tires. I have the drop arm and track bar relo mount installed. It tracks and steers perfect. I do not have any bump steer or wobble. I will say it took soke time to get the track bar adjusted right but when I did it was solid and no problems to date.

Tbe ideal situation is neither but I run a little over 6 inches of lift and I used both to get it back to stock.

Every place you read and get advice from say the same, both or neither.

I've since changed to a non-drop bracket JKS front track bar but that was mostly for clearance issues... The track bar drop bracket contacts tie rod at ~75% suspension compression.

You use both drops or no drops. If you try to use one without the other you are messing with the geometry leading to death wobble, shimmy, and overall "funky" responsiveness and steering/stability problems!!!!!!!!

you do NOT want to install a drop pitman arm.

the only occasion for installing one is the use of a frame side drop track bar bracket, and considering drop track bar brackets have a tendency to hit the tie-rod, there really is no occasion to install one of those either.

FWIW, the inclusion of a DPA in a kit is typically a sign of a low end kit from a company that doesn't understand basic geometry.

Patrick H Unless you lower the track bar bracket, don't installed a DPA. In fact, don't do either.

00tj2 Well you better hold your horses and do some reading about front suspension geometry..... You are making a big mistake if you install that without remounting the trackbar. The trackbar and drag link follow the same parallel path throuout the suspension cycle. When you add a drop pit man arm you are changing the relation between the two which in turns causes the front wheels to turn as the front suspension cycles up and down. This will cause "bump steer" and make your jeep not very fun to drive. To explain a little more, when you add a 4" lift the frame side of the trackbar gets raised 4" and so does the drag link to pitman arm mounting point. If you use a drop pitman arm you will now have the frame side of the trackbar mount higher than the drag link to pitman arm mounting point. This will change the relation between the two bars and cause the above mentioned bump steer. Im pretty sure i did but I hope that I have explained it correctly.

This works, but as I said, I personally try to avoid putting that kind of shock load on the sector shaft

Patrick H You can use a pickle fork, but they tend to damage the dust boot, and I don't like pounding on the sector shaft. I personally use an adjustable pitman arm puller to remove the pitman from the steering gear, so I can drop it down enough to put the adjustable puller on the drag link end of the pitman to remove the drag link from the pitman arm. Takes about 5 minutes total.
