Yes, because the rubber is rotten and needs to be done anyway. What do you think?

Do you think a misalignment could cause the vibration? Thanks!

Upon thinking about it more, the vibration disappears if I put it in neutral, so it probably isn't the issue.

If the desired angularity might become greater than what it is designed to be, then a shudder on acceleration can occur. Mainly on acceleration, though.

The front u-joint is more prone to wear than the rear u-joint seems to be, which can result in highway speed vibrations. In the case of our '66 Newport, I started to hear squeaks on take-off from a red light, but would vanish at higher road speeds, when a higher-frequency vibration could be felt when I'd put my right arm on top of the front seat back while cruising down the highway. Vibrations had been there a while when the squeaks started.

I pulled off the wheel covers, but the squeaks still happened. One trip around the lot at the Chrysler dealer and the diagnosis was the front u-joint, which we always kept greased. Replaced it and the highway vibrations and squeaks ended. "Like new" again!
