Wj Highway howl

Hey guys,
04 limited with 4x4 and the 4.7. At speeds above 65, I get a weird howl, only under acceleration. If I let off the gas, the noise goes away, floor it, goes away. There is no other noise associated with it, no vibration at any speed. I don't remember any locking or chirping at low speeds, no clunk when shifting gear from park to reverse or drive. It only occurs at coasting above 65mph.

I slid under it, no movement on the diff end of the driveshaft. There is a little play on the tcase side tho. I can barely move it left right up down. Would that cause the howl?

What I've found online indicate a bad pinion bearing? But there's no growling or grinding, and no movement on the diff end of the dshaft.

This isn't my jeep, but best mimics the noise and when it occurs.

In the description he has the broken spider gears vid where he believes the problem was....


Is this where I should focus first when I put it up ?

Can you drive it on jackstands and pinpoint the source that way?
