[Vibration when power Send to the Front]

Hello ,

 

A Little Update ..

I added the red line oil to the transfer case and still have the same problem.  I checked the front differential and can't really find anything there either... I looked in with an endoscope and will show you the pictures!

sorry for the bad Quality ..

Thank you BK!  Of course I realize that you can't tell me exactly where it comes from, but your tips have already helped me a lot!  I've had the car since 2019 and of course I can't say what the previous owner in Japan did with it.  But everything is series except suspension, rims and exhaust.  One thing came to my mind… I also have vibrations at ~1500 rpm from the Front. When i Hold the rpm at 1500 approx ( car stands and no difference With pushed clutch ) . Last winter i installed a fluid damper without much success... .  During a short ride yesterday, however, I noticed that the frequency of the vibrations is very similar to the other vibrations.

BK so you Would Rather say its the Front diff?

With the clutch discs, I mean that they grip, don't grip, grip and all of this at a very fast speed and this creates this frequency because the vibrations are in every gear at the same frequency even at higher speeds

Hello Tranks for Your answers!
 

I'll check the front diff in the next few days.  Yes, the vibrations only come from 25% force going to the front axle.  Maybe the clutch discs are worn out and sometimes not engaging and that's what's causing this pulsating vibration.  What do you all mean ?

Hello Tranks for Your answers!
 

I checked the Front an rear diff ratio and they are both identical. When i checked the Ratio I found that the front diff should be an open one

Tires are new and I also tried another set of tires with different rims and unfortunately it's still the same …

Maybe could it be the Atessa Clutch Packs in the Transfer case ?

thanks for helping me !

Hello sorry ..

its Hard to describe 

You can feel the Vibration in the steering Wheel and pedals. it comes from the Front / middle to the Front of the car.
the vibrations are always at the same frequency no matter what gear I'm in and only when power is given to the front axle.  I would describe the vibration as pulsing.
