Subject: crack in gearbox case & vibration between 140 and 150 mph (230-240 km/h)

Hi, i have that 2 problems i already mentioned in the topic with my MY90 9000T, the biggest one of them is that i have a crack in the gearbox case rightt here where the two halves meet each other, at the differential. any idea on what i could do? welding is not really possible i guess and nothing else would stay there given the vibrations, heat and the oil pushing from above, but if someone has any other idea, please tell me. right now ill stay with refilling about 1 liter of oil every 4 weeks :( and the second problem is that after replacing both front wheel bearings and rotating tires front-back i get a strong deep vibration on the highway between 140 and 150 mph its most noticeable, it feels like the vibration you get when the car is at very low rpms and you push the gas. also i feel some strange kind of "play" not really play because the wheels go where i point them to, but a feeling like something is loosing contact to the ground, like lifted up inside, when i accelerate between, well 70 and maybe 100 mph. does this rather sound like track rod ends/balljoints, cv joint or maybe just the motor mounts? otherwise the car behaves just fine handles well and doesnt make any cracking sounds, just a bit of clunking sometimes in stop n go traffic, but i believe that are just slightly seized brake calipers. any advice greatly appreciated bye simon
