Hi, I've got a strange vibration issue while the car is moving. The vibration appear between 80 and 140 kph and there is no clear pattern. Sometimes i can feel the vibration at a certain speed, say at 120, but other times there is no vibration at all. I haven't been able to narrow down any pattern on when it appears except the speed range 80-140kph. At low speed vibration is mostly in the seat/body and higher speeds it's in the steering. I have visited multiple mechanics with a lot of checking and components replacement done but issue hasn't gone completely.
Below has been replaced:
Front suspension strut
Front upper and lower control arms
Steering tie rod ends
Front differential mountings
Any other bushing showing failure sign
Both rim and tires
All the rear bushings
Drive shaft u-joints only front one for the front shaft and rear one for the rear shaft
Wheel Balancing and alignment has been done multiple times. Engine and gear mounts are okay.
The issue remains and i can't seem to find out what's exactly the problem
