Flat tow... pulls / turns left

Ok, I want to flat tow the jeep. Got it all hooked up and after a left or right turn the jeep turns hard left and stays there. I've googled the heck out of it.

Looks like it may be the Caster? Any ideas or what is your .02?

I did just put new lower control arms on seems to drive good maybe a bit of sway back and forth but not bad... seems to track straight while driving.

Going to get alignment first thing tomorrow if I can find a place

The fact that it goes left for left and right turns tells me it's not castor but that's just an uneducated guess.

I thought if the caster was bad it would stay turned whatever direction it was turned last, aka the symptoms he's describing?

LUCKILY it was alignment... couple issue but mostly one lower control arm was 3/4 in longer than the other Had not had aligned sine new control arms. Lesson learned
