the 306 is wandering like fook! , changed the drivers track rod end for mot and passenger ball joint as failed,wandering went but now come back worse than ever, but only does it under acceleration in 3rd,4th,5th. 1st and 2nd fine but soon as in 3rd and accelerate wanders right quite hard and you need to turn into it,back off and it moves back left, any ideas? since changed other track rod end also,tracking ok but not had chance to look since
