Went to the local NAPA dealer to check on some parts as they said they have complete control arm/ball joints for $72. Sounded too good to pass on. They said there were no differences between the left and the right side. Mazdatrix lists a left and a right. The technical data cd I have lists left and right. Does anyone know if there truly are differences between the left and the right??????

 

Yes they are different. If you look at them, you'll see they have holes drilled for the tension rods(I think that's what they are called). The holes face to the front.
