Grinding/growling noise coming from rear end

[marek4792]

Too high or too low ride height will cause vibrations and grinding noises, also is the cheapest thing to check. If the noise/vibrations persist then pull the axle shafts out and put the truck into gear and check where the noise is truly coming from. Better and safer then jacking up the truck and having to navigate around spinning tires and rocks projectile launching.. Also a good time to check bearing endplay. Tighten and/or replace as needed to manufacturer spec..
