Ok found out what was going on. Talked to a Nissan dealership and they stated that if your car pulls to one side and then you rotate the tires and the car now pulls to the opposite side it's in the tires and it's called "radial pull". So after fighting with the local Discount tire dealer and telling them the car is fine it's the tires finally they gave in and replaced the tires and swore up and down that it would not fix my problem. Guess what they were DEAD WRONG. The problem is fixed, car drives nice and straight, feels like a brand new car again. Just thought I'd let ya'll know what came of it all.
Thanks for all your help and suggestions.
