Yes it can be right, some Peugeot`s are the same and are bad for breaking rings on shafts,I did contact a motor factors and they did supply rings separately but they would have needed the old ring for comparison and would entail stripping the front suspension to fit the ring,it depends how handy you are with tools,another option would be a scrappy for a 2nd hand shaft to cut costs.
