Question about 1999 GMC Suburban
On my 99 4WD GMC Suburban, I have a loud roar/vibration at 55 to 65 MPH. The vibration is constant and will not fade or change pitch when decelling or cornering or any other attempt to change the frequency. What is the most likely cause?
Check your u-joints

Start by inspecting your tires. Look for uneven tread ware, tire separation (a bubble) on the inside or outside. Then change the fluid in your front and rear differential. This will tell you if you have a gear problem. Change the fluid in your transfer case also for indication of a gear problem.
