wow! thanks for all the quick responses everyone. you're right it could be anything, I've yet to go to the mechanic, but i'll let you all know what they say.

in response to Wingking, I'm actually still on winter tires, ( I KNOW! ) haven't had the time to change 'em up. Could definately be ONE of the problems.

thanks again all, will keep ya posted!

your halfshaft is siezing up or you have dirt in it (not a cheap fix). Did your mechanic tell you, you will need a cv boot when you went in for your oil change? CV boots are very common on the xi modles. all the info you gave is pointing at them i do so many cv boots on xi modles its not even funny. Just take a look under your car and if there is a coat of thick grease on your rim and surounding area that is your problem. if your feeling vibrtions already then you need a knew one i think they range anywere from 600-1200 a peice.

hey guys,

so...after going to the mechanic every other day to get around my work schedule, seems like the vibrations have nothing to do with the tires. We did a wheel balance, checked the rims for imperfections, etc. My mechanic finally took it out for a test drive and says he's pretty sure it's the propeller shaft. Apparently it takes a while to inspect, so i've dropped off the car for the day, and he's gonna hoist it up and have a look. Annoying, but he seems pretty confident he knows what's wrong with it. I'll let you all know what he finds tonight. Thanks again for all the responses!

that thing always acts up when it doesn't get the 1.21 jigawatts of power it needs, my fix for that is to install a Mr. Fusion power generator, it can run on all kinds of garbage.

WOW!

So after a lengthy journey, and STILL no answers, I've managed to catch the attention of the shop forman at BMW Autohaus. Even HE doesn't know what's wrong with this car. Here's the situation. He's narrowed it down to a few things. Since it's an xi model, he said something's up with four-wheel drive. It could either be the transfer case, the front diff, or the cv boots. He suggests that I spend the money and pay him to look at the transfer case. He ran a few tests including locking up the transfer case and hoisting the car to drive on the rear-wheels. When he did that, no vibration. When he got the car to run only the front wheels, it started shaking from 0-40. His bet is on the transfer case. So now, he plans on taking a transfer case from another car, and putting it on mine to truely see if that's the problem. If that doesn't work, it could be the front diff or the cv boots, or WHATEVER. But it's my call on what the hours should go towards. What do you all think? Is it the transfer case?
