Default Gradually increasing road noise '95 Toyota - 09-30-2005 , 10:45 AM






I'm getting a gradually increasing road noise on a '95 Corolla, 80k
miles. The noise is pretty anoying (can't hear the radio).
I had previous experience with road noise getting louder on Japanese
cars around 10 years old.
The noise doesn't change when turning, but it changes depending on road
surface. The tires are relatively new (1.5 years old).
I wonder if it may be related to some suspension rubber parts getting
harder over time.
Wheel bearings maybe?
Any suggestion on how to fix this will be appreciated.

Is it just wind/road noise?

I replaced the door seals on my '94 before a cross country trip this
summer. It made a huge difference in blocking out wind/road noise.
However, it cost me ~$180. If I wasn't going to be driving 9k miles in a
month I wouldn't have bothered.

How are your tires? I know you say they're only a year and a half old,
but how much tread do they have left? Are they wearing evenly? I've
heard tell of some tires getting significantly noisier as they wear,
especially if a slight misalignment is causing them to "feather" any.

The tires have about 3/4 tread left.
They don't seem to wear unevenly, except a bit more wear on the outer
tread.
I wonder why would new door seals make a big difference.
The original ones don't seem to be torn or in a bad shape.

You are probably correct about rubber parts wearing out and hardening.
I've noticed the same thing with my vehicles. I usually replace them
with stiff poly ones between 5-10 years. That just about doubles the
road noise but helps the handling.

Same thing happend to my wife's '95 Prizm (mechanically the same) about one
and a half years ago. Worn struts caused the tires to start cupping and
increased the road noise to the point that the radio had to be turned way up
and the hands-free cell phone system was useless.

What rubber parts should I change for a noticable improvement?

All of them.

Run your hand over the tread surface. Is it smooth and even?
