Hey all, 127k miles on my '02, 4.0L, minor lift, 31s. Had been running great then I noticed a type of 'hum' when coasting or decelerating. Its consistent but there's a pause between each hum. Its not a clunk or a squeak that I've been finding here through search. When I press the clutch or put it in neutral it completely goes away. Lifted up the front wheels to look for play or a wheel bearing issue but all seemed ok. Checked front differential fluid, was a tad low but just a few ounces. Any ideas?
Thanks!
I should add I've been running the RPMs up higher lately as I've read about the 'lugging' thing that I had probably been doing before.
All fluids are up to date.
