A 3200 story. I have been suffering with drivetrain vibration for some years and have been gradually working my way through the whole system, starting with the back axle area, 18 months ago I could feel some slack in the rear drive shafts, so I replaced the wheel bearings and drive shafts and had both rear shock's re-furbished. I inspected the diff and was fairly sure its not the source of the vibration so I left it alone at that point. After this work it was better but not solved. So I got under it again and decided that the center bearing that supports the prop shaft seemed to have a bit of movement and so the prop shaft would need replacing. After picking myself up off the floor at the price of a new one, I got a low mileage second hand one from Ireland. I recently got round to changing this and once I got it all apart it was clear that the final drive shaft bearing in the gearbox extension housing was also gone, and i was surprised to find the nut holding the drive coupling to the gearbox had come off completely. I managed to get a replacement bearing and a new shaft nut, but not the oil seal on the extension housing output. I got a seal company to make one up to order and after a couple of aborted attempts got an oil seal to fit. rebuilt the whole thing (prop shaft, exhaust, steering rack, ARB) and it was running so smooth. I was in heaven. And then I took it for a run. The special made oil seal was not made of a high temperature material and softened and started to leak! So luckily after some searching McGraths found a genuine Maserati Oil seal for the gear box and within the next 10 days I will tear it all apart again and replace the oil seal.
Not sure there is a moral to this story other than these cars can try your patience, and if that oil seal on the gearbox of the auto goes, Maserati don't make them anymore so make sure the seal is rated for 220C, the seal size is R40X67X7, and must be FPM or Viton not Nitrile.
