Fellow 02 Faithful,

I'm getting a strange and vexing noise from, as much as I can isolate it, just under my right elbow in the transmission tunnel.

The noise, which is frustratingly sporadic, but increasingly reliable, seems to come most following a long highway cruise (20 minutes) and is most pronounced as I'm slowing. The fact the the sound is a very high-pitched squeal and really stretches out when the car is practically stopped makes me think drive line over wheels, because they're hardly moving, but I suspect the drive shaft and anything upstream of the diff turns at a much higher rpm, right?

After checking the books and the archive, I'm inclined to suspect the center bearing. I'm a bit surprised by this, however, because I put a rebuilt drive shaft in just a few years and about 30k miles ago.

Also, there are times when it actually sounds like two separate sqeaks singing in an evil harmony. There's also a bit of a dragging/pulsing that coincides with the sound.

Braking doesn't seem to affect it one way or the other.

If it is the center bearing, the books suggest a fairly easy removal, but offer only the "suitable drift" guideline for reinstallation. Anybody know a good kludge? Is it that tough to get the new bearing on?
