Yeah apparently you can remove the front driveshaft and if it's not marked for phase, and you put it back, it is out of phase and will wobble But I mispoke, it's not the drive shaft, it's the front axle shaft, so yes, I'm out in left field on that one. Not the front driveshaft me thinks. The vibration, regardless of acceleration, starts at 35 mph and progressively gets worse up past 50 mph, then settles out a bit...but it's still present. I'm having the brakes done at the same time, so I'm thinking I will have them check the CV joints and the hub/bearing assembly. I have also read that bad strut will cause this issue too. I'm not opposed to new struts and shocks, would make the ride nicer, that's for sure. Thanks for the response, I'll keep you posted.
