1996 Mazda 626 tie rod end or control arm bushings?

I have a 96 mazda 626 dx and when I bought the car the kid told me that the tie rod end was no good in it. Now this is on the left front of the car also when I bought it the tire on that side was bald. When I get in the car the suspension makes a small squeak this same noise happens when I hit a bump on the road. Also the car pulls to the left side when im driving it and when I turn the wheel I hear the same noise. Now my question is. Is it the tie rod end I should replace or the control arm bushings? And also is it safe to drive like this or should I take it off the road untill I repair it?
