Bass noise coasting in 4wd
I noticed it today when I was driving 30-50mph coasting or off the throttle. It sounds like bass. Thats the only way I can describe it. In 2wd it's quite. The axle is a LP D30.
Front drive shaft? T-case? Front axle? Crush sleeve? Pinion bearing?
I'm going to swap my back driveshaft to the front tomorrow and see if that fixes it. I'll also inspect the Yoke
Any input is appreciated.
