Cab and wheel shake

I’ve been trying to solve this wheel and can shake for months have replaced carrier bearing aligned new tires balanced new wheels new exhaust and cannot figure it out. There is a very slight vibration in park at idle you can only feel in the seat. The shake progressively gets worse at higher speeds any ideas?

 

While in idle? Any noise associated?

Have you checked your body mounts recently? Especially if you live in a rusty area.

 

I can check the body mounts the rust is not bad idk how to check a body mount being bad also could that be related the more annyoing part is in the steering wheel

 

I would check the Trans. and motor mounts also while you're under there. Good luck.

 

I’ve checked motor mounts how do I go about checking my trans

 

I was referring to the Trans mount. If I remember correctly, they have a history of becoming loose. Just a guess though.

 

That's a 2WD issue looks like OP has 4WD.

 

So I looked at body mounts all look solid I got under and started truck up idle at park felt things that vibrate it seems the trans itself and the rear driveshaft is vibrating at idle

 

Bad alignment? Getting worse at speed points to a rotating assembly, is the driveshaft clocked properly?

 

Check a body mount? Get under the truck, find the body mounts under the cab, you'll probably just see a big 3"-4" wide washer with a bolt coming thru the bottom of it. It'll have rubber above the washer. Grab the center bolt and try moving it around. It shouldn't move.

Maybe I'm confused by your 1st post. You said it happens in idle, and you feel it in the seat. Now you're saying you feel it in the steering. And you said something about it happening as you increase speed. I find all of that confusing.

Repeating it back: If you're in idle, you feel a vibration under your seat. When you're driving in gear, you feel a vibration in your steering wheel?

Are you in a rust-prone area? i.e. living in the "rust belt"?

Look at the crossmember holding the transmission in place. Move towards the middle of the vehicle. Do you see all bolts intact, there should be 4 going up in the transmission housing. Does the mount look good, rubber looks good?

 

Alignment done 2x now not really just progressively gets worse

 

Clarifying the full issue I can feel in the entire cab if I feel around the floor the steering wheel the console everywhere it’s very slight but gets as speed increases including the steering wheel and everything else in the cab I felt down below on actual parts the mounts for the body are okay the frame doesn’t vibrate that much u can feel a vibration in the trans and the driveshafts front and rear

 

You have 4WD. That means you should be greasing all zerks on the driveline every oil change basically. The slip yoke zerk specifically has a quirky process that's not very normal IMHO. When was the last time you greased the driveline?

 

I never have only owned truck 4 months

 

If you have no baseline, then I highly recommend you get off your ass and read this thread to deal with the driveshaft lube, then this thread to get caught up on the truck if you haven't already read it.

I would assume whoever did the driveshaft work should've lubed the entire damn driveline. But you never know.

What exactly has been done to the driveline thus far, and who did the work?

 

Sounds like a torque converter to flex plate bolt/bolts that is or are loose or has come out. Possible cracked flexplate. That cause's your issue. Worth a peek.
Not much reason to start with drive shafts if its vibrating at idle. In park!
Consider what is rotating in park. Start there.

 

We've had a couple of members have cracked flex plates, and all I remember complained about a rhythmic rattle at idle that wasn't the normal injector tick (or whatever ticky sewing machine sound many of us hear). There's some links to examples in the start here, new owners thread, in the 2nd reply 'recalls, TSBs, annoyances' section.

I think this is one of my faves: https://www.tundras.com/threads/2005-tundra-with-engine-rattle.101270/
