Intermittent vibration, DS bearing??
Hi,
2010 325d E91 RWD 150k miles Recent PS4/5 tyres and balance. Reasonably recent shocks and suspension overhaul. This first happened on a long drive at cruise control 70mph. Felt like I drove over very rough tarmac or rumble strips and slowly increased. I slowed to about 50 and it slowly went away then stayed away for the rest of the 200 mile trip. A month later (had only done shorter trips in the mean time) Did 240 mile drive last night, no issues Came back today. Same drive same speeds 70mph I got this vibration about 3 times. Again, feels like rumble strips I can feel it in the car and the seat. It’s an auto, knocked it into N and no change. Tried speeding up and slowing down and it just changed the vibration. Slowed to about 50 and it faded away Then back up to 70 and all good for about an hour till it did it again. Accelerates fine. Not engine dependant. Doesn’t seem to be brakes. Does this sound like the centre bearing starting to go? And getting some resonance going on and getting worse till I drop enough speed to stop it and then it smoothes out? Or more the rubber flex disc? Cheers Andy Last edited by Andy198712; 09-23-2024 at 03:45 PM.. |

Had a look under the car today, checked front and rear rubber flexis and the centre bearing, gearbox mounts and suspension parts
The rear flex has cracks in it which is going to be my first thing to change as the rest looked okay, front flex looked good, couldn’t feel play in the centre bearing or the UJ’s I could deflect the rubber in the centre bearing a very small amount but I espected this as it’s rubber. Here a pic, |

Something I noticed after cleaning the car was my rear right wheel had more brake dust.
After a short drive I could touch my left hand disc but my rear right disc was too hot to touch! So seems it’s a sticking caliper. Going to check the pins first and if it’s not those I’ll do a re man caliper |
