Rattle and vibration on take off then goes away

2014 Tacoma trd sport 6speed manual 4.0L New to this forum stuff.. when I begin to take off at low rpm 1K or less (truck is moving and clutch is engaged and foot off the clutch pedal) I get this loud rattle noise and vibration and then goes away after around 1500 and above. This happens in any other gear if I accelerate while in the 1K range. Looking for insight.

 

Otherwise stock? Miles? Rattle/vibration vs shudder? Are you familiar with clutch shudder? Quick check for a rattle be heat shields along the exhaust. If more of a vibration thing - check the drive shaft at the carrier bearing - check for excessive signs of wear/heat - lift up/shake the drive shaft to check for slop.

 

Rotating parts have a critical speed at which vibration is at its most extreme. It can change over the life of the equipment.

A deformity in the drive shaft can effect the balance. So check the shaft in addition to the u joints and such.
