Re: WHY DOES LINCOLN MKX MAKES ROARING SOUND BETWEEN...
Things to check (in order of likelihood):
- Fluid level and condition in rear differential;
- Drive shaft center bearing;
- Rear outer bearings;
- Front bearings (have they been packed with grease in the past three years?);
- U-Joints
- Tires (separating tread, flat spots, etc.)
