2013 SR5 Vibration Identication - Help Needed

Breaking down on another vibe thread after it feels like I've reviewed every thread on this subject. I do most work myself with exception of the rear wheel bearings. Hoping to get some pointers as next places to look, at a loss at this point. I've never owned a vehicle with such a poor driving experience.

Symptoms:

• Buzzy vibration when accelerating felt in pedal, wheel and floor. Vibration is very fine, not like an out of balance wheel. More prominant with more throttle, smooth coasting.
• 45mph turns into a pulsing in wheel (not wobble) Happens in gear and in nuetral, more prominant while decelerating/coasting so seems specific to speed not rpm comes on again at 25mph. If i drive at 45 mph will pulse consistently until past that speed range at any throttle
• Appears to lug like a MT at low throttle in lower gears (2-3), increased throttle triggers gar shift and removed lugging. Overall just sloppy shifting after owning manuals for the last 10 years.
• Excessive vibration stopped in gear at lights etc. in seat/wheel
• Not sure if seperate, moving wheels while jacked up at 9/3 o clock gives a repeatable clank like a mallet on thin metal, could these symptoms be from tie rods?
• All symptoms present in 2wd and 4wd

2013 DCB SR5 78,000 miles - purchased July 22 no lift/modifications
Already Replaced Below

• Center support bearing -toyota *crunching/torn/excessive play
• all u-joints -spicer *done while doing above
• Spark plugs, cleaned maf/throttle body *preventative
• Rear wheel bearings (both)
• Front wheel bearings (both)
• ECGS bushing - excessive play
• New Michellin LTX M/S stock size 3x rotate and balance thinking tires could be culprit
• Inspection of suspension seems good with exception of above note regarding clank

 

does it do it in 4wd?

 

Appreciate the reply! it does in both 2+4, updated above

 

helps if i have better reading comprehension...I see you already said that..the clank..hmm..can you get under it when this happens and narrow it down? got me stumped...

 

Added after your comment

^ Added after your comment for thoroughness. Tough to pinpoint but "centered" ie: if I wiggle the right or left wheel it sounds equal in distance from center of the truck. Cannot locate exact location but happens from both wheels.

 

check your steering rack, man...without being there this is a tough one.
