Light vibrations at 2-3000 U

Hello together! I have some problems with my XC90! It was built in 2006, D5, automat and ran 178 tkm. I drove a longer highway route last week and felt very light vibrations when accelerating, which at first felt like a power loss. I then got off the track and I missed everything relevant. Engine speed in idle, oil level, past blowing injectors, noises from the turbo. Nothing eye-catching! I thought sh I had hallucinations and wanted to go on. There I have the funny effect when starting, so at 2-2500 U already again. A bit unnerved I latched on the gas and immediately the effect was gone. I then rolled home relaxed at 140. Hardly off the highway, I had of course in the city traffic immediately this effect again, but I made it home with a little more gas and some ignorance. By light much then looks at me up the upper engine bearing. It was full of Thanks to Polar, I had a new bearing and new torque supports in a very short time, unfortunately it didn’t help. Maybe the effect can’t be felt so clearly now, but it’s still there. From my point of view, it has to be a defect somewhere in the drive train, because the effect only occurs under load. Forward more intensely than backward. Before I start to exchange any parts on suspicion, I would like to have your opinion. Thank you already – No, no, no, no, no, no, no, no, no.
