Manual shifter movement

I've now had my 00' TRD ext cab Tacoma about a month, and 2k miles. Ive noticed on the highway I feel a shake in the seat, and the shifter moves around a lot. Ive never seen this before in a vehicle ive owned. I dont think its tire balance...but I will get them rebalanced.
So do these driveshafts go out of balance ? Or is it a sign something has failed/or is failing?
Thanks

 

shifter moving around is normal, but the shake in the seat sounds like maybe a worn out carrier bearing.

Start getting used to it squeaking, popping, shaking, etc. These trucks are reliable but they don't ride all that great haha

 

If the shift knob/shaft has a direct, mechanical connection to the transmission, it will move around & “shake.” Notable should be specific movements based on what the drivetrain is doing (moves based on torque & part movements- small but noticeable).

Many modern “manuals” are really electronic transmissions with old-style elements & not directly connected to the tranny’s moving parts- ie-> the clutch directly moves fluid/levers that engage the clutch, while the shift know actually moves levers that move shafts & directs the gears.
The mechanical shifter physically sticks out of the tranny, through a hold in the vehicle floor (sealed with rubber boots), then to the driver’s reach- a physical lever to control gear movement.

Electronic “manuals” give no “feedback” as they lack any direct, mechanical connection between the shifter & the tranny.


If severe movement, something may be “wrong” ...
If you can, drive a similar stick (as close as possible) & see how they compare.

 

Marlin Crawler is the place to get Toyota shifter bushings.
Watch their video. Super easy for anyone to change the shifter bushings.

Not sure about the shake in the seat, but it could be the transmission mount? It's easy to check, just get under the truck with a prybar and a flashlight then lodge the prybar between the transmission and the crossmember and pry up and down a few times while inspecting the rubber blocks to make sure they're still attached to the steel.

 

I cant explain it well, but it definitely seems like abnormal movement. I think I am going to start with tire rebalance...they look good but are 10yr old. And the more Im focusing on the shake, it seems like it could be.
I figure if the tires are really shaking, they'd be bouncing the rear end...causing the driveshaft movement to move the trans around. I suppose starting with an easily ruled out issue is good place to start

 

I'll check that out, I havent crawled under neath to look at anything yet
