I have an 09 Rubicon and am having a Teraflx BB kit installed as we speak. Are the stock arms not adjustable for castor?

Correct, the stock arms are not adjustable. You need to go with aftermarket adjustable arms to adjust the caster angle.

 

But, with only a 2.5 BB, I don't think control arms are a neccessity.

 

Ahhhh...Thats good news. There wasnt any mention of required control arms purchase when I picked the BB.

I heard that too and my 2 door developed DW on the way home fromt he install. My castor changed from 4.2 (stock) to 2.8 (afterwards)

TF told me today that 2doors are more suseptable for whatever reason. So LCA increased my lift cost by 50%...

 

If you keep the stock arms, and lift the vehicle, you will ultimately decrease your castor. And if you decrease castor too much you may get deathwobble, though other factors are coming into play here. Are those numbers measured by you or an alignment rack.?

 

The stealership's align rack did the measuring.. so its accurate. So now I am off to install some LCA and see if this solves it.

Its an interesting mystery to solve, but its keeping me off the trail. I don't like that.
