Re: 33\'s and no lift???!!!
I had the same problem with my steering once, and it was due to the adjusting screw being tightened too much. All I did was loosen it a little and lock it down. Now it works perfect.
As for a steering stabilizer, get one put on after you adjust the steering, and then make adjustments as necessary. It will help with the potholes. I have the Rancho Single Shock one; the dual should only be used if you go up to 35-inch tires.
Hope you get the steering situation worked out.
