OK, I have a 96 328 with about 122,000 km.
I am noticing a vibration from what seems to be the mid/rear of the car. It's not violent but it is quite apparent.
At first I though it was just the wheels out of balance but it doesn't feel like that.
I can really notice the vibration at higher speeds.
So, any diagnosis? Wheel bearings maybe? I'm going to bring it to my mechanic but I just want to get an idea of what it could be.
Thanks.

u are very unspecific about when it occurs.

from now, it say guibo

guibo symptoms:
when u are accelerating
vibrant shaking, its the driveshaft
gets worse and worse

its really not that bad, if u do it urself, once u take out hte exhaust, ur all good, and taking out exhaust isnt that hard lol

I have the exact same car, and the exact same vibration, my mechanic said it is a carrier bearing in the drive shaft. He wanted $250 to fix it, and said I could not hurt the car by driving it, so I am driving until I can get the extra $250, but I would bet you $100 it is the carrier bearing(or something like that)!

The guibo typically goes out before the bearing does since the guibo is a load bearing elemnt. It's constantly under stress when your driving, the bearing just holds the axle in place so it dosn't go anywhere.
It could be the bearing, but most likely it's the guibo. Take a look under your car right at the transmission output flange and there will be the guibo. Feel it (if you can reach it without jacking it up on some stands) and if it has cracks in it, you need a new one. When you have a really bad vibration, usually there are chunks missing from it.
You could have some other bushings worn out, usually the front conrol arms or ball joints will cuase vibration while driving and sloppy steering. Since you say it feels like it's coming from the back, 4 wheel alignment or an out of balence wheel will also cause this. (see if one of your wheels didn't just throw a weight). You really just need to get under the car and check all of the moving joints and axle connections, if anything looks worn or loose or has any play in it, replace it (eavenly on side to side.)

Any way you might be able to show a pic of what I am looking for sometime. This is my 3rd bimmer, but I used to think that they were so foreign, I never took time to try to do any of this stuff myself(and I love working on cars). Now in process of looking for a new career, need to be a little more money cinscious!!!

this post was very helpfull. finally i know the name of what that part is haha. I had to replace the guibo not to long ago. and wow my guibo looked ten times worse then the ones in the pictures. You should replace it asap. Also check the bearings that can lead to vibrations problems also. I had to replace my right rear bearing not to long also. My fault for peeling out and racing to much haha =0p

Thanks guys.
I'm going to bring it in this Saturday but it's good to know what it could be.
