Hi, try adding fluid first to see if it will solve the problem, if it does you do not need to change the wheel bearing but if the noise persist, am afraid you have no option than to change the wheel bearing......

WHY DOES LINCOLN MKX MAKES ROARING SOUND BETWEEN 40-75 MPH


Things to check (in order of likelihood):
  1. Fluid level and condition in rear differential;
  2. Drive shaft center bearing;
  3. Rear outer bearings;
  4. Front bearings (have they been packed with grease in the past three years?);
  5. U-Joints
  6. Tires (separating tread, flat spots, etc.)

I have a 2009 altima. I hearing a roaring noise


In my 2005 Nissan Altima I experienced a roaring noise from the rear of the car. It ended up being the rear wheel bearings needed to be replaced. It appears that this is a common problem with Nissan Altima's & Maxima's of varying years even with fairly low mileage. This might be your problem.

What is causing the loud howling from my 2002 Suburban?


Hello I don't know exactly where you live however, I'd say the loud " roaring noise is possibly the clutch fan. The reason why they are so loud and make the roaring sound is because as you accelerate the fan blades spread outward but are under resistance .It's activated by ambient engine temp. They are very noisy when engaged and tend to work more on rural roads, stop and go and when A/C is being used. etc. The brake light is on because the fluid is below the fluid level sensor basically telling you to check and or add brake fluid. In addition the ABS light has came on because it had ran low on brake fluid sending a warning signal to the computer from the ABS brake control module. The best thing to do is to keep up on the fluid level find that leak and repair it.

Rear end on f-350 makes roaring noise. I checked oil level and it was ok. The oil seems to be very thin. Could wrong oil cause rear end noise?


Differential roaring noise is usually caused by a bearing that is worn or has pitting in the bearing race (half of bearing without rollers). A whining noise would be caused by worn ring and pinion gears. the roaring could be from the carrier bearings (two bearings holding the differential case to the axle housing) or fron the pinion bearings. The fluid is typically heavier but will seem thin when hot. The fluid isn't the causing of the noise but if the wrong fluid is in the differntial it could have caused the bearing to go bad which then causes the noise. good luck.
