I have a good idea of how the steering is set up in Scania Solar/Rural.
No matter how much enginnering is done to them there still going to be a bad bus.
The only enginnering that will fix the steering is to move the steering box to under the cab floor at the base of the steering column the way it is in a Tiger or B10M. In a Tiger or a B10M the steering column is connected stright into the top of the steering box, then 1 drag link connects it to the front axle.
In a Scania Solar/Rural the steering box is infront of the O/S front wheel, which means there is an angle drive at the base of the steering column and then a 3 foot long driveshaft going to the steering box. There is then a draglink connecting it to the front axle. The joints in the driveshaft will wear along with angle drive. Usually creating tight spots in the steering. This driveshaft and angle drive are extending the length of the steering gear. All it takes is for the shaft not to be correctly weighted or for the weight to have fallen off and it will cause a vibration creating steering shake.
The only thing I dont really understand is how a Scania is nearly 12ton unladen yet it has no chassis, yet a Leyland Tiger or Volvo B10M are only 8 tons and these buses do have a chassis and big tyres and big heavy engines
