 Farm tractors and lawn and garden equipment have often used them in this application, and even some higher-power applications, such as some 1960s race cars, featured them.In automobile and truck prop shaft designs, they have now mostly been replaced by constant-velocity joints or driveshafts with pairs of universal joints.Rear-wheel drive cars have commonly used a lengthwise propeller shaft with a rubber doughnut joint at the gearbox end (limited movement) and a universal joint at the rear axle (greater movement), or vice versa.
