Strange noise at 45mph
Hi there. Just recently I've started getting a noise just like grinding metal - like a blade being held against a sharpening wheel - at exactly 45 mph. It stops when I go beyond or beneath 45mph. Very strange.
Any ideas?

One other thing - it happens regardless of whether I'm coasting or driving and whether I'm speeding up or slowing down. Always exactly at 45mph.
Thankyou for having a think about this. I appreciate it.

It also makes the same sound, only much quieter, at about 63mph. It's really loud at 45mph though.
Does that sound like a drive shaft issue to you? Any suggestions you may have would be greatly appreciated because I'm nonplussed at present.

Its possible that could be the issue. Or, there could be something wrong with another suspension component that is making it vibrate through the driveshaft and back under the hood. I had somewhat of a similar noise on a relitives car but it was a ford taurus and I replaced the wheel bearning and it was gone. I would pu the car up on jackstands and see if you can grab the tire from top to bottom and try to wiggle it. If there is play then that could be the issue. If you do this from side to side then it could be a tie rod end that is worn out. If you remove the tire, you can grab the drive shaft and, it will have some play in it but, if you notice excessive play it should be replaced. Hope this helps.

When the car is makeing this noise and you move the steering wheel left or right will the noise change ?? if so the right wheel bearing is bad ..more than likely..

The new noise sounds like I've got the car in too low a gear, but it seems to be coming from the rear of the vehicle and happens whether I'm in gear or not.
I'm starting to think that this is all connected to the rear suspension or bearings. Last time I was out, when I went over a bad bump the rear end got a little squirrelly. Like I was being blown around by strong winds. I need to replace the rear bearings, don't I?
