Strange noise at 25 mph?

Could it be tyre noise?

Wow,

Someone read my mind, I was going to ask the same question yesterday but did not get around to it.

I have heard the rumble also, mainly when I am accelerating 25-40 mph, low rumble sound.

I also do not hear it all of time.

I look forward to what others have to say.

Thanks
Don

I've read where several people have had their differentials replaced for various reasons. But sometimes I wonder if it's just not the normal sounds a differential makes, and because of it's close proximity to the drivers ear (about 2 ft.) that it's simply a noise we aren't use to hearing.

I also feel this slight rumble/vibration at 30-37 mph, usually when I first start out with the car. It definitely feels like its coming from the rear and first I attributed it to rough asphalt, which I was on at the time. Then it happened when I was on a smooth road. I figured it was a tire slightly unbalanced since it was so specifically happening at only that speed range. Now after reading your posts, I'm not sure. I'll definitely check it out--it doesn't seem any worse now than when I first noticed it and it's not there every time I'm travelling at 30-37 mph, but often enough. Any other suggestions?

low pros usually get bumpy (uneven patern on the thread) after a while and creat rumbling noises.

to verify, if its in the rear, lift up the rear end(and put it on jack stands). turn off traction control, then run the wheels around the speeds u hear noise, this will prove if the noise is from the tires or the driveline/diff/bearing, etc.

Thanks Racer!

no prob,


try this tho. look at the thread on the inside of the tire width. and slide the palm of your hand along the thread, around the tire, if u feel like a bumpy pattern, thats the tire u wanna replace. tires with low thread also make a womping and bumpy ride at certain low speeds

Hmmmm, short wheel base car, your butt sits nearly on top of the diff, big open sound amplifier just the other side of the bulkhead, I would say a hum would be normal.
Kick up the sound system to 40 and forget about it ! :p
