- '99 5.0 Limited AWD
'99 5.0 AWD with 210k. Good tires/brakes/shocks/exhaust.
Nothing loose.
I'm starting to notice a slight groan/rumble/vibration that reverberates up from the drivetrain on acceleration - particularly under load, or up a hill. More noticeable accelerating from a stop or moving slowly. It sounds/feels like it's coming from the rear. It's not a constant 'crunch, crunch' like wheel bearings, & I don't hear it when not accelerating.
In previous cars, I recall this sound/vibration as a result of bad u-joints, so I replaced both (I have to say that I was amazed that both original u joints were in decent shape/still had grease).
No change after new u joints.
I'm guessing a bearing/bearings in the rear diff.
Any ideas?
