Noise from rear normal?
What I notice is a subdued howl or humm from the rear when I let up on the gas in 5th gear in the 40-70mph range. If I apply any gas at all, it goes away.
It is there to a much less extent in 4th.
Is this normal for an aging car, or a sign that something is wearing out?
With the top down or radio on, I am not conscious of it, so it really isn't that loud.
