no--bearings and tires are the most likely cause of roaring--esp if it gets louder as you roll faster
The grinding noise you hear are your shocks and struts. If you experience bouncy while you are driving, as well, you should have them changed.
It is probably a wheel bearing if it only does it while moving.
Struts wear out on a car because they tend to rust. A person that does a lot of winter driving will probably have to replace struts in a car once while it is owned, if kept for a long time.
Remove the muffler
Not sure what you mean by "jumps". Maybe you need new struts or shocks.
the wheel bearing on the vehicle will make a roaring noise when you accelerate the faster you go the louder it gets
Sounds like a drive train problem or perhaps a wheel barring issue, depending on your vehicle.
It could be the shocks/struts or something in the steering system...have it checked out.
it may be the drive shaft u-joints if its rear wheel drive
Yes because during braking your tire will loose contact with road which will affect our stopping distance. it will also cause waves on the tire and when you do replace your struts you will have a vibration while driving
No, this will not damage or cause wear on the struts in any way.
It's time to replace the struts on a 1998 Toyota RAV4 if you notice signs such as excessive bouncing or swaying while driving, uneven tire wear, or leaking fluid from the struts. Additionally, if you experience a rough ride or hear clunking noises over bumps, these can also indicate that the struts are worn out. Generally, struts should be inspected every 50,000 miles and replaced if necessary. Regular maintenance and check-ups can help determine their condition.
