Engine & DrivetrainDiscussions about the engine and drivetrain of your vehicle.
This is a discussion thread titled "Engine vibration at 1500-1600 rpm?", within the Engine & Drivetrain forum, part of the Technical & Vehicle Assistance Forums category.
Just noticed in my new-to-me '02 SEQ that the engine has a vibration that you can feel in the driver's floorboard at around 1500 rpm. I read a post at edmunds' Sequoia thread about someone else noticed this. Any input or known problems/fixes? Thanks for any help as I like the new ride alot but wasn't expecting such a buzz from a reportedly smooth drivetrain.
My '04 Seq does the same thing... I know the vibration is directly related to the engine because as soon as I let of the throttle the vibration stops.
I can't remember who told me this, but someone said it was causeb by "exhaust building up in the exhaust system". I have never heard that one, but who knows...
I'm convinced that this is an engine-related issue as it occurs sensitive to engine speed, not wheel speed (i.e.- in any gear, not at a certain mph). Anyone else have noticed this? Thanks.
More information might be helpful such as any modifications like exhaust, suspension etc, total mileage, type of drivetrain, options. Could be something as simple as the serpentine accessory belt is stretched and is vibrating, or maybe a defective a/c compressor, belt tensioner pulley. Kind of hard to guess in the dark.

If a combo of all these whizz bangs met their claims you'd have to syphon gas out of your tank every second day and sell the excess horsepower on the third????

Mine seems the most noticable at 66-71 MPH.
Whoever told you that should NOT be giving out advise! Get in your truck, and quickly drive the other direction.
The only thing close could be the 2000 RPM drone....it wouldn't be felt at 1500 RPM in this engine, and your exhauast would have to be modified and have the resinator removed to feel it at 2000 RPM.
The Seq is bone stock with even a brand new set of original style Bridgestones. I notice the vibration when the engine is under a load maybe even more like 1400-1500 rpm, especially when starting up a hill and the tranny hasn't downshifted yet. Anyone else have this problem? Any input appreciated. I hope I'm not just overreacting, but I bought this thing to keep for a looong time.

I'll leave out any internal engine stuff because that'd be too hard to fathom. I think I'd check the engines accessory drive equipment first. You may still have the original serpentine belt which probably should be changed anyway before it starts to squeal on cool mornings. The a/c compressor you could check by turning it off or on several times through that rpm range. Power steering pump by turning slightly if possible again in that rpm range. Beyond that it gets tougher to check possible bearing issues with the belt tensioner and idler pulleys short of removing the belt and rotating the pulleys by hand to feel any roughness. After that you get into drive line checks but if it does it at the same rpm range in each gear that's pretty well eliminates drive shaft or axles. You didn't mention if it was a 4X4 and I'm not familiar enough with all it's rotating hardware to speculate vibrations there. You didn't mention mileage either unless I missed it. The more info you can provide about the vehicle and when the vibration comes and goes temperature wise (engine & ambient) , incline, decline might help a member provide some input.

You will not be able to get this fixed. It is a characteristic of the both the Sequoia and Tundra. Look at the other disccussion threads on Sequoia vibration, driveline vibration etc. No doubt you feel a buzz in the gas pedal as well as vibration in the floor ?
Sorry, I'm a newbie didn't know exactly how to reply to this. My 05 Seq. has just over 60K miles and has this weird vibration as it makes its first shift. It seems to shake the drive train slightly. But it is in consistent. Almost like temp. outside maybe effects it. Makes me wonder if it is a Tranny. problem. Hope you find what it up with yours. If any one has heard of this problem any input would be greatly appreciated.

Yes, exact same thing on mine. It only happens at a very specific rpm range and under load before a downshift. I can feel it in the floorboard and the gas pedal. I did a lot of searching and reading and with this particular issue "they all do that" became an acceptable answer (for me). Certainly they dont all do it, but it seemed common enough that I stopped actively looking for the cause and just learned to ignore it. Like regnew62 said, its just seems to be a quirk of the Sequoia/Tundra.
toyota will do nothing about it. been told that by three different dealers. most tundras have it. mine does. annoying. kinda like the motor mounts need changing at that rpm range. mine does it in park and neutral aas well which makes it an engine issue. something obviously isnt balances properly in the design.
i had to come to the clonclusion that the perfectobile project was blanked by the big 3 and there will never be a perfect vehicle made. tough for someone as ocd as me.

i have a 2000 tundra and i have checked the alignment of the drive shaft there is a string method explained in the forum. and that helped the next step is to replace the carrier bearing some call it a drive shaft support bearing. when under the truck i found that he rubber boot supporting the bearing is torn and the shaft is allowed to move around a about 1/2 inch in either direction. also there is grease splattered on the floor of the truck.... it is something that you could do if you have a hydraulic press. o'rileys carrys the beraing for 100 bucks or you can have a drive shaft shop do the work for you and have them go ahead and replace the u-joints and balance the drive shafts as a unit. the shop will balance to much tighter tolerance than the assembly line.
i had this done on an old 1985 diesel surburban and the vibrations went away.
this is my chore for this friday am. i will let you know if it took care of my vibration.
at 43 mph and rpm at 1200 or so .
Engine vibration at 1500-1600 rpm?
