Driveline Angularity

Driveline angularity is the angular relationship Low speed vibration, less than 72 km/h (45 mph), between the engine crankshaft, the driveshaft and especially when the vehicle is subjected to heavy loads on the rear axle pinion. Factors determining driveline acceleration or deceleration is an indication of angularity include ride (spring) height, and engine improper driveline angles. When these conditions exist, check the universal joints for proper seating, mounting and operation.
