w114 -72 Vibrations
Hi
I have a vibration in my car from 60-80 km/h. Very distinct in this interval, nothing outside. New balanced tyres. New flex-coupling. No differance with clutch engaged or not. No difference acceleration or not. Any good ideas guys? It takes a bit of the pleasure out of my cruising...

It sounds like one of two things.....
You have lost a balance weight from your driveshaft. If you look at your driveshaft closely you will see some small flat curved bits of steel that are glued to it. Those are balance weights and they are glued on, not welded. If one comes off you will get a vibration just like you are describing. Or you are needing to replace your carrier bearing. The bearing itself is on your driveshaft but it rides in a bearing housing which is sometimes referred to as a Spider. The bearing wears out and starts to tear at the Spider and that will also cause vibration, but usually only on acceleration. You might have your driveshaft checked by a shop that can balance it. Once you have it out go ahead and replace your carrier bearing and housing since a two piece driveshaft is always balanced as a unit. If you have a three piece driveshaft, and some 114's do, then you will have two carrier bearings and you will need a shop with a very special piece of equipment to balance your driveshaft. Most shops can do a one or two piece but few can do a three piece. But they are out there; you will just have to find one. |

Do you feel the vibration in the steering wheel or in the seat? What does the shifter do when the vibration happens?

It feels all over ;-) Will check next drive. Going to India for 3 weeks working, will have more time when back. Maybe easier to exchange driveshaft then balance it? If I can find a good one. Actually, I would like to change to a 5 shift transmission too..

Then I super glue them back on. Because that's the way they were put on to begin with. |
