Need to replace seal in front differential. How is this done? Also, truck making a roaring noise in front noise gets louder and quieter when speed of vehicle changes.

Is it a pinion seal or axle seal? Also, if you hear a noise, you may have to take things apart to see if the bearing in the differential is bad. A bad bearing may be what caused the seal to go bad.

Let me know.
