I only had my valver for 3 weeks and it's giving me sum amount of hassle. Wheel bearing went , then the front shocker decided to start leaking. Got my local garage to do the bearing £50 so not too bad. just put a new shocker on but already theres more trouble lurking (typical french engineering). Does any one know what would cause severe shuddering through the whole car but mainly from the front end when accelerating? It only starts at about 4000rpm then fades of at about 5000. The only thing I can think of is that one of the cv joints is screwed. Any ideas guys?
