Dude, its not your alignment. When was your last brake job? At 50k, you are ready if it has not been done. I'm thinking sticky calipers if it is brake problem.
Also, pull your tranny dipstick and see if the fluid is clear and clean. The color should be bright red. If it is dirty, might need service and inspection. Thirdly, check differential fluid by pulling fill plug. After removing, wipe plug on a clean white cloth. If it is dirty with metal flakes or other particles, suspect differential gears or clutches if it has limited slip.
