well you are kinda right, they ARE different. Aftermarket parts are gay. I spent 3 weeks one time to get back an axle for a spirit 2.5 sent out as a core. I had to have it 'made' at a shop. That was a long time ago, i learned my lesson. Even the mopar books aernt always right. I just give the aftermarket companies an OE number to cross and they are like that doesnt fit that car. Uhh yea it does. But yea the manufacturer DOES matter. I had a Caravan one time that spit 4 axles, didnt even make it off the lift, and come to figure they all were car axles, from Carquest (reman).BUBBA said:Well, it's funny you mention this. The last axle I got looked a little bit different from the previous 2. There's no way to specify which axle style I want/need at the parts store. The axle manufacturer shouldn't matter so long as it's made for the same car and the length is the same.
