As the title says, I've had this whirring, howling, vibration when I hit highway speeds, >50mph.. I've had the truck at 3 different techs; 2 of them felt the vibration, but neither of the 2 had any ideas of what it might be. They checked rear driveshaft u-joints, wheel/tire balance, alignment, front wheel bearings/hubs, and said the rear axle bearings seemed tight.. Truck is a 2004 Ranger 4x4 ext Cab.. Rear axle code is: 97 (Open 4.10 w/ 10" drums).
I've replaced: front UCAs, stabilizer bar links/bushings, front shocks, one of the front wheel bearing/hubs, front driveshaft..
Bearing tolerances of both front/rear axles seem fine to me.. I haven't been able to check pinion angle, and what I do know is that my leaf spring bushings are a little beaten, and I do have signs of s small leak around the output seal of the t-case..
Vibration feels like it's coming from the middle/rear of the truck. I can feel it in the pedals, but it doesn't feel like a warped rotor/drum. The truck does it in neutral, and the vibration gets worse going downhill, when coasting or off the throttle..
Any ideas?
