vibration

  1. #1
    hi, im getting a vibration roughly between 40 and 60 mph mainly while accelerating it feels worse in gear 5 than in 3rd/4th, started when i replaced de cat pipe for standard manifold for mot and the centre section came loose, tightened it up and it got better not as violent and nearside drive shaft has been replaced again also replaced offside strut at the same time.
    anyone know what this could be? thanx
