2002 Kia Sedona suspension problems

Our sedona has been pulling since we first bought it. First to the left, then to the right, then nothing, no pull. Been aligned twice. Also been told I take my hands off unevenly which causes to pull, also that I don't know how to keep correct tire pressure in. The car pulls heavily. One way or the other. Scared to drive. Also brakes vibrate car badly when braking from high to low speed especially on a downhill. Have contacted the bbb auto line.

Front end suspension was tight when new. Now the front end makes sounds as if something is loose and about to fall off or break. Dealer said it was normal! Other 2002 kia sedona's don't have that feeling in the suspension. I have read that other's have had their suspensions fixed by changing components such as struts, bushing, seals, etc. Kia knows something is wrong with the 2002's because test drives show the 2003's don't have that sound of shacking front end.
