I just installed my 3.5" flex system rock crawler lift this weeked and in runs great and straight. It felt to bumpy, so I read to airdown my new 35" falken peak on pro comp 17" tires to 30 lbs and it rides so mush smoother. The only problem is that when driving slow my steering wheel moves back & forth just a bit if I hold it with both hand it stays put. Is this a wablle? When the tires where inflated to 50 Lbs this did not occur.

My jeep is a 2009 4 door unlimeted sport w/ 3.73 gears and my final lift gain from center hub to under the fender is 5.625".

I can post photos after I get off from work.

Thanks for any advice.
