W124 driveline vibration
When I acquired my W124, the drive-shaft carrier bearing had completely failed. I marked both segments of the driveline with a paint marker before I removed it. Everything went back together fine. I used a new rubber carrier and a new bearing.
The flex disks both looked good, no cracks or fraying at all. The U-Joint appeared to operate normally. Both CV shafts and boots look good. The driveline has a vibration that presents itself at about 62 mph. My assumption is that either someone had the driveline out and didn't mark it, or perhaps a balance weight fell off. If I go pick up a wrecking yard driveline to rebuild, does it make sense to take new flex disks, carrier bearing and bolts in and have everything all balanced together?

the driveshafts are marked from the factory, one is a triangle with its other husband mark - you have to align both. There are heavier nuts available from MB to counter a vibration problem, They even have a solid rubber block that is bolted to the diff mounts in case of extremes.
Usually its best to do the easy stuff first. I also read somewhere that the carrier bearing can be shimmed to make up for lost alignment of the driveshaft. Another point to see is the driveshaft bushings on either end.

I'll do the free thing first, climb under there and make sure the marks are lined-up. I read another comment about at least making sure the tabs are lined-up end to end (as in not off-set from each other); from memory, I couldn't even swear to that. Thanks!

Maybe not the driveshaft, how about tires or tire balance?

I have (on a private road out in the middle of nowhere) gone from zero to 100mph to zero, in a perfectly straight line with zero steering input.
The sound, and the vibration sure seem to be coming from the center of the vehicle. Guess I could pay to have the wheels balanced. Tire shops are always cheesy though...they try to upsell, every time. |

Could be rear spring or transmission mount is bad then you got the wrong angle at the driveshaft.

Engine mounts as well as the previously mentioned trans mount. Relatively easy to change. I'm fighting a driveline vibration as well, have not done mine yet.
