Balanced tires and still get a binding noise

Hey everyone, I wrote a post about 3 weeks ago or so about my car having this wierd low vibration/binding noise around 15-20 mph. The impression I got was my tires needed to be balanced and rotated. I did both of those and still and getting the same symptoms. Also ive noticed lately that it seems like the car almost has wheel hop when cruising at 15-20 mph. If im in lets say 3rd gear and doing 20 mph its almost like the car is slightly jerking back and fourth. Im really lost as to if its my tires or what. Also this vibration can be felt through the brake pedal. The vibration is fast enough to tickle my foot when in the given range of 15-20. I know its not the brakes because wouldnt the rotors feel warped when stopping at other speeds? Also why would the symptoms remain when the brakes arent even being applied. Its like something is binding up somewhere in that speed range. Im really at a loss on this one, and dont want to take it to the stealer because i just hit 36002 ironicly. I have the extended warrenty if this problem will be pricey. But then again i would like to avoid using it at all costs. Thanks for any feedback :SNSign:

Im almost positive that its not a warped rotor because at 15-20 mph there wouldnt be a very fast vibration also the vibration goes away when not in the given speed. Same with the bent axle or wheel I just cant see it going away when i speed up. The car drives fine at 25-90mph. I think the alignment is a possibility, i do get a squeek from the shocks at random times so ill check those out. Also its wierd my tires are wearing a lot in the middle infact they're down to the wear bars where as the outsides look like new. I have them set at 33PSI as the manual and door tag calls for. What is bumpsteer 03ghost? Sorry for the noob question. Ill look at the tie rods when I was the car today. If worse comes to worse ill just take it to the dealer and have them deal with it.
