vibration after 70 mph after new axel install

[nightrider]

ok so my axel went so i replaced it but now there is a weird vibration after 70 mph, it used to be completly smooth till about 145, (aparently my top speed), should i be worried about the vibartion, could i need a wheel alignment?

yeah was the same thing that happend to my bro's sti when we put on some sway bar. We found out that it was not tiend out. it was just losse alittle and that is why it happend . maybe there is something that is losse. What kind of Axel did you go with cuz i'm going to have to get two soon.

After you change your axle you should always get a wheel alignment done.
