VIBRATING ZODIAC

I’ve got a Mk3 Zodiac and there’s a slight vibration in the car. I have had the spiders/UJs renewed due to knocking but I’m still left with a slight vibration. Any ideas? John McCartney Email

A It sounds as if you may have to get the propshaft balanced. When the UJs were done, did the person who did the work mark up everything before dismantling it so all the bits went back in the same positions relative to each other? Most engineering workshops should be able to rebalance the prop for you, otherwise try a prop specialist such as Reco Prop or Propshaft Services who are part of Bailey Morris. The other question is can you drive through the vibration? If you find that the vibration occurs at a certain speed, and if you drive faster it disappears, it could be that your rear wheels need balancing.
