And here was I wondering what I was going to do tomorrow (not). The Xantia has a Tripod joint on the long shaft (R/H side) which will wear and give extra movement. I replaced one on the previous car, a BX 16V, which vibrated at times under hard acceleration. I notice the Xantia is just starting to show signs of doing it to. I haven't noticed any excess lash in the diff. at low speed as yet. http://www.aus-city.com/ubbthreads/images/icons/default/frown.gif
