2001 330i wierd noise at cruise speed...

[yammahamma]

I know I just bought this car so this kinda makes a little mad that this noise has shown up....it's under warranty so I hope that this is fixable under the warranty...

It's an '01 330i with 80k miles...

When your maintaining speed (at just about any speed) - and by "maintaining speed" I mean not on the gas but not off the gas - there's seems to be a loud rumble/road noise. If your listening you can hear it at 30 mph but when your going 65 it feels like your on the rumble strip on the highway. It doesn't feel like un-balanced tires....it's only when your maintaining speed. If i set the cruise control it will "rumble" until I either accelerate or de-accelerate.

I'm going to have it checked out this week and hopefully get it fixed under warranty...but I just wanted some opinions before I start getting estimates.

Any ideas?

Thanks!

As a guess, maybe the drive shaft u joint might need a look.

Just got her fixed....turns out it was the CV joint on the drive shaft and the drive shaft coupler.

a cool $1k.

they said they've never seen this kind of problem before.

Glad you sorted it!

[yammahamma]

yea, the coupler was almost in pieces. The bearings had completely broken through the housing.

I'm telling you. Never trust those old retired lady previous owners :rolleyes
