Hi i have 56 nissan primastar 85k , had a bad sqeaking noise when i went over speed bumps had to replaced 2 new plates that the ball joints sit on last year both sides , got the parts from eurpoarts £160 plus mechanics fees , went for a mot this year failed saying 1 plate has too much play so went back to euro parts and as they were a year and 4 weeks they wont do any thing , so had to but 2 new nissan plates £270 plus mechanics fees again , so lesson learnt i wont be buying major parts for the van other than manufactures , guys who have the trafic vivaro primaster be careful of this and also i have heard if you get a engine management light come up with injector problems beware this is expensive changing injectors
