My '90 DX h/b has a steering wheel vibration most noticeable at 90-110kph (54-66mph), but when im on a long bend in the highway it dissapears halfway through the bend only to return when im going straight again. ive recently installed machined rotors, 4 ball joints, right lca shock fork bushing, front end engine mount, all of which needed doing ive aslo tried 3 sets of ballanced wheels/good tires since the vibration started. none of the above has had an affect on the vibration. im beginning to think its one or both axles. Has anyone had axles create a steering wheel vibration? Any other ideas?
