XC90 speed vibration (self.mechanicadvice)

I've been procrastinating a fix for a vibration that is speed related on my xc90. It starts around 45mph and comes and goes up to 65 or 70... I broke some stuff 'diagnosing' it, and once I fix that I'm going to take the awd driveshaft out. I'm assuming a bearing is bad, any ideas? I want to repair the driveshaft because it's really expensive to replace.

It could be as simple as needing your wheels balanced. My car had a shudder that started around 70mph. I thought my wheel bearing was going bad, but the problem went away after I got them balanced.

Interesting, do you know if I can check them at home?

I don't have any experience with it, but a google search tells me it's possible to do at home with a bubble balancer. A tire shop would be able to balance it quickly for not a lot of money though.
