330xi Vibration When Coasting

Hi all,

I've started noticing a slight vibration in my 330xi (manual) when coasting on the highway. Its not really a big deal, but it is becoming progressively more noticeable. Vibration goes away when I'm on power. Most of the front end suspension is relatively new (25-30K) and about 5K on the rear end suspension since replacing most of it. About 102K on the car. Wheels are balanced and not bent.

I'm thinking it could be a worn out guibo, but I've heard that's relatively uncommon. Any thoughts? Thank you all in advance.

I had a vibration when coasting in my 335xi. It also squeaked but only when coasting. The issue was worn front drive shaft joints. When coasting you're not putting tension on the u-joint on the drive shaft so it wiggles back and forth when coasting, then when under accel you're putting twisting tension on it so it can't move back and forth. My guess is the front drive shaft or possibly the rear drive shaft joint.
