Hi everyone. I just like to know if anyone has faced this issue or not and if so what was the problem.
On the freeway when i travel over 110kms right through to 140-150kms even when i back off the throttle i get this vibration or harmonic under my seat. Not through my steering wheel.
Now i have done the auto extension housing bush and seal, another balance on the tail shaft with new uni's, full recon. diff which i got the axles checked for straightness, brand new diff gears and brand new truetrac and rotated my wheels front to back. Still there.
I have changed my rear top and lower trailing arms with the heavy duty Nolathain arms a long time ago. But when i did do the trailing arm a long time ago the car ran so smooth at thews speeds.
Maybe i'm thinking stall converter bolts or converter. Maybe i'm missing something that anyone here can share a light on my issue.
