New to a lift and question on my spacer Lift
Just bought a 2008 JK unlimited. It came with a 2 inch spacer lift/ 20 inch wheels/ 35 inch tires. My old JK did not have a lift on it so I am wondering if how my new JK is driving the way it is because of the lift. When I drive and lightly turn the steering wheel side to side it feels "Loafty" or almost like it you are floating side to side. I didn't have this with my 07 JK Sahara. So the question is... is this normal with a lift or is there something else going on.
Side note... It just had new Ball joints put in!!

As suspension height increases, the axle rotates, which raises the pinion. As the pinion rises, the caster decreases. As the caster goes down, the steering gets flighty. The higher you go, the lower the caster gets, and the flightier the steering gets.
If you choose to correct it, you will want to rotate the housing and lower the pinion again. Your options are Cam Bolts, control arm Brackets, a set of longer/shorter 'fixed' control arms, a set of adjustable control arms. (cams are cheap, but read some reviews before going that route...)

First thing is get rid of the 20" wheels! Just kidding to each their own. I agree with nthinuf but with a 2" spacer lift you shouldn't be exhibiting or need to change all those things. I have a 2" spacer lift on a 2 door and don't have any issues. Being it's a 2008 I'd check for bushing wear in the track bar or steering. Maybe wheel bearings? A lot of things loosen up over the years. Good luck.

The weight of the wheels/tires will also effect the steering. Wider, grippier tires, especially those that are mounted on heavy 20in wheels, will cause flex on the factory steering components, especially the factory track bar that will cause the symptoms you are describing.

You need some caster correction. Although 2in isn't much of a lift and some may not need to adjust caster after a 2in lift, you need to keep in mind that no 2 Jeeps are the same. Some leave the factory with low caster where any amount of lift can send them over the edge into the land of flighty steering. Pick up a set of geo correction brackets for $100-$150 and you'll be all set.
P.S. Nice Jeep! I like the Reds, but I'm partial to the blues. I saw a Blue JL today when I stopped into the dealership to pick up a part, and that was almost my tipping point to go purchase a new JL since the darker blues tend to be a specialty limited color which disappears after 2 years. Red, Silver, White and Black are available every year.

What tire pressure are you running? A lot of my complaints about flighty steering were solved by lowering the tire pressure after a chalk test. When I bought mine it had 33s on it, at 44psi. I almost didn't buy it because it drove so bad. After doing a chalk test I'm at 25 cold and 29 hot and it drives great.

Maybe I'm just reading the OP differently than most. I'm not seeing you complaining about twitching steering (which is why most are implying caster is too low). I'm not saying your caster ISN'T too low, but it sounds like you're just talking about the jeep feeling more floating on the road....like a big boat? Or are you indeed talking about floating as in you can't control it well? Some of this could just be the fact your center of balance is now higher compared to what you were used to before. You got more air moving below you, and that does change how things feel a bit. Are the shocks just worn down and need replacing? I described my wife's Armada as feeling "floaty", and it's amazing what some new shocks will do.
