To find the location of that point draw a line in plan view through the diff centre towards the front...

For a twin steer system the drag arm from the steering box is connecting to an idler arm mounted on the chassis and swinging in the same plane as the arm on the steering box...

    Johnny I will try to explain what it means.Looking at the car from the right hand side, imagine a lever arm solidly attached to the rear axle housing and attached to the car frame a distance y forward of the axle.Torque about the wheel axis will be the driveshaft torque times the diff ratio,call...

    My understanding is that axle tramp (live axle)is caused by driveshaft torque unloading the right side tyre so that it looses traction. When traction is lost driveshaft torque reduces and the tyre is forced back into contact with the road, driveshaft torque increases the tyre is lifted and the...
