E30 highway vibrations

[Adam Lazur <adam@xxxxxxxxx>]

In the past week or two I've been getting progressively worse vibrations
during highway driving in my '89 325i (about 130k mi, 5spd). It comes
and goes, some days vibrating during the daily commute to work and some
days not.

Here's how it goes:

I begin to feel mild vibrations around 45 or 50 in both the steering
wheel, shift knob, and a little in the gas pedal when the vibrations get
worse. If I increase speed to 60 it gets worse and I get a more serious
vibration and a slight hum. The vibration then varies in severity all
the way up to 80.

I originally thought I just needed to get my wheels re-balanced, but the
vibration feels more like it's in the drivetrain.

Anybody have any ideas?

I'm taking the car in to get new brake pads in the next few days, and
will ask them to look at this, but I'd prefer to have an idea of what
kind of stuff may be wrong.

Along those lines, anybody have good/bad experiences with Stuttgart
Motors in Lexington, KY?

Thanks in advance.
