Steers Like A Cat On Crack - wtf?

[Mayle]

Ever since I got this thing I've notice that it steers REALLY easily, and by easily I mean move the wheel an inch and you're in the other lane. I know high tire pressure can cause it but I checked all around and made em 35psi. The mechanic said I need an outer tie rod end on the passenger side up front so maybe that has something to do with it. Any other ideas about this crazy steering? Im gonna end up in a telephone pole soon if I dont fix it!
