Stock pitman cause Death Wobble?

I have been battling DW for the past 9 months now ever since getting my 2006 Rubi lifted with an RE express 3 inch lift kit. I got the shocks, springs, and adjustable trac bars. Jeep drives fine with stock 31s, which i have on now. When I put my 33 BFG ATs on, all hell breaks loose. These 33s came off my old 94 wrangler and I painted the rims black (1 can of duplicolor wheel paint each) before putting them on the 06. Never had an issue on the 94 with the 33s.

I had everything in the front end and rear tightend and triple checked. I had the 33s balanced three times to make sure, yet i still get the DW with them on.

i took it today to get aligned again to see if that is the issue and the guy said it was slightly out, but not by much. He said that my issue is the stock pitman arm and that I need a drop pitman in there to bring everything back to normal symetry.

Now, I heard people talk about tightening this and that, balancing tires, etc, but i never came across anyone mentioning that the stock pitman was the issue.

Any thoughts and should i get one. Appreciate the insights.

Jack

the 3.5 RE doesnt come with a drop pitman arm
my dad had death wobble when he put the same lift on his jeep but he is still running the 32in. tires that were on it when he bought it

we put a drop pitman arm on it and got the drag link and the track bar in line and that cured it

If you installed a trac bar relocation bracket, then you should also install a drop pitman arm, but if you are running the track bar in the stock location, then you should run the stock pitman arm. I have not heard of this causing "death wobble", only bumpsteer, which is a different issue.

If you have to ask what it is or what it does, you don't need it, and you will need help to install it!

Exactly. Do NOT install a dropped Pitman arm when the trackbar is still mounted to its factory undropped upper mount. The trackbar and Pitman arm go hand in hand. If one is dropped, the other must be dropped. If one is dropped and the other is not, bump steer is the result.

Having or not having a dropped Pitman arm has NOTHING to do with Death Wobble. If as you said elsewhere your tires are perfectly balanced, I'd then look at your toe-in and make sure it's to spec, and make sure your trackbar is mounted TIGHT... I have the ft-lbs. tighteness specs in your JF posting. You can't just grab the trackbar with your hand as a test to see if it's tight enough. It can feel tight enough yet still be loose enough to allow DW to develop.

I heard of my buddy the other day saying his pitman arm causing something like that too. is that even possible? Unless its the actual steering box or the splines i dont think its possible. Any reason for it?

can you describe in more detail how to check if my drag link and track bar are in line. I am not a mechanic, so if its possible to eyeball this, let me know.

get a torque wrench and check how tight they are. Most trackbar related problems come from a loose track bar at the axle.
