Techstream live data analysis

Postby plumedelan1 on Wed, 16 Mar 2022 3:27 +0000

Hello,
I'm French, sorry for my bad english.

I have a Hilux Revo 2GDFTV bought in 2017, I have a vibration problem which appeared at 45000 km, the vibrations appear during the first 10 km, between 1400 and 2000 RPM, then disappear, no garage finds the problem in france, and they don't want anything to do with it, I did the recording hot and cold, and nothing surprised me. I also have a recording during vibration.
Could someone watch and analyse my recordings?
Thank you.

Are you shore it is engine and not speed related
Vibrations cames down to tyre, tall shaft, wheel bearing.

I have tried warming up the engine before riding and have no problem, so for me anything after the clutch is not the cause.
When I am freewheeling there is no vibration.

Regards.

When you freewheeling the load cames off things like the tail shaft universal in centre bearing.

I have vibrations on the accelerator pedal side, only during the rise in temperature, when I'm hot I have nothing.
If I'm in neutral in a mechanical gearbox and the vehicle is stationary, and I accelerate empty, I feel the vibrations a little weaker, the vibrations are proportional to the engine speed, around 1800 rpm.

Thanks, best regards.
