3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
Just got a 2001 330ci with 49k on it. Car is perfect except for a little suspension issue? When going slow speed (15-20mph) the car has a grumbling noise in the front-driver side, and the car will veer side to side. However when I go at faster speeds, these problems seem to dissapear.
I took it to several mechanics and they drew several conclusions:
1. Hub Bearing
2. Bearings in general
3. Uneven tire wear.
In the end the last mechanic that actually lifted the car said that it would most likely be a tire issue. However I wasn't too sure that he was even too sure about his own assesment. Anyone had a simliar problem and can give some feedback?
I have the same problem in my 2000 323Ci. I put new tires on but the problem is still there. That means my next step is to replace the bearings. At 50K, the bearings are usually shot and you get loud road noise at about 20mph.
The closest I have ecer come to this is in a Z3. I have driven many Z3s and if they have 16" wheels they drive beautifully. However, when they have 17" wheels or higher, the steering has a mind of it's own!
Grumbling noise from bearings - it is unusual for both wheel bearings to "go" at the same time. Therefore the grumbling noise would be only when turning one way, or steady and constant all the time from one wheel, and you would feel it throught the steering wheel.
My conclusion is that it is tire noise and that you have oversized tires that are making the car "Tram line"
I had exactly the same problem you are having.
I took my 330I to discount tire and found out that I had my rear passenger side tire worn out more than the others.
Also, the tire pressure makes alot of difference. Make sure you have the right pressure in them.
I replace that bad tire with my spare and vola the noise and the vibrations were gone.
