Lift questions / death wobble/ p0421,p0431...

I have a have a 06 Jeep wrangler Ruby with a Rubicon express lift, but am unsure how to tell which one it is since it was on there when I purchased the jeep. Does anyone know if there's an easy way to determine this? I believe it's a 3.5 but possible it's a 4.5? Also would like to know what package it was so I can build around it. I'm mechanically inclined and have always worked on all my own stuff but have very little experience with lifts. I Also have the death wobble issue to address ( thinking its wheel bearings) but not 100%. She's also throwing a p0421and a p0431 code ( warm up catalyst). Looking for places to start with that issue as well. Thanks in advance for any help

Take a measurement at your frame behind the front lower control arm bracket. Tell me that and your tire size. I will give you my measurement and we can take a guess at your lift. You could also look up what different components come with each lift and see which ones you have.
