thank you for the reply... ive had the balance rechecked and it was shaking before the new tires so im sure that's not it. The alignment I haven't had checked but it doesn't pull or anything. The lug nuts are tight ive checked that, haven't checked the axle nut.

From what ive read... most people say its the cv axle since it does it under a load only so ive decided to go ahead and install a new one tomorrow and ive ordered new tie rod ends so hopefully thatll fix it.
