Bad input shaft bearing?

Hey All,

Here's my rig:
2001 Tacoma 4x4 TRD xtra cab, Manual, 130k
New tires, belts, clutch, center support bearing, shocks + struts & fluids. Pretty much stock.

Here's the problem:
Once the drivetrain is warm (after my commute over HW17, ≈ 1800ft mountain pass) I get a rattle coming from the floor when accelerating (low rpms) in 1st & 2nd gears. It kind sounds like play in a bearing. Also once everything's warm, I'm getting some vibration when accelerating @ 60mph.

I'm thinking maybe a input shaft bearing. Thoughts?

 

worn bearings dont usually rattle, get some audio & I'll tell you in 30 secs or less if its an input shaft bearing, a lot of whining on take off & acceleration

 

Your the "MAN" 4 WD! Wish I wasn't so tone deaf!

 

an input shaft bearing will usually make noise in all gears except 4th if it's bad, and also when idling in neutral. Mine was a rhythmic tap/rattle.

 

Mine was noisy in 1st...2nd 3rd 4th nothing... 5th....holy shit it was loud no rattles

 

Thanks guys, I'll try to isolate some audio for ya.
