It has started to make a horrendous moan at 45 but settles down after you hit 50.
Just make sure to use some lube.....:gr_grin:
But seriously though. Check your differentials for proper lubricant might be low or one of them might be on it's way out.
I bet you if you push it towards 80-90mph the sound will come back at an octave higher
My friend had a Cherokee that starting making a moaning sound at around 40mph and would go away once past that.But then would come back at around 80mph at an octave higher. It's like when you rub the edge of a wine glass. That same kind of sound you can feel all the way to your bones. It was the rear diff, it went out after about 2 years of doing that. They never bothered to get it looked a. even with my incessant nagging to do so.
