I've read a but about this but getting a vibration under car at low speed (not always though) and mechanic thinks it may need a new propshaft but perhaps it could be one of the bearings that could be worn?
Any ideas on what to look for most welcome to give mechanic some ideas as he's an independent and not necessarily a fiat specialist. Car is c. 86k miles so perhaps should be expected?

Hello, and welcome,
ask in the panda section , as there will be a few now who've covered these mileages,
there are a few specialists out there now too,
