Rear axle drone?
I have a 1994 4.0 2WD (manuel trans) that recently between 55-65 mph I start hearing a drone sound as if there is a semi truck getting close to me. It gets a little bit louder up to 75-80 mph. It doesn't get better or worse as I decelerate or accelerate. I am in the process of changing the fluid in the diff between yesterday and today (it was time to change the fluid anyway). The internal diff looks fine. No excessive wear that I can see, no shavings or broken teeth. The truck has 275K on it. Has anyone ever had this issue that they can shed some light on where to look or a check list?
Also, does anyone know of a better way to refill the diff? I have a 5/16" clear tube and it is frustrating to say the least.
Thanks in advance for any helpful advice!
