Running torque defines the amount of torque a component needs in order to keep spinning at a constant angular velocity after it starts spinning. Measuring running torque is important for identifying quality issues with an assembly or defective components.


Trucks with 8-lug wheels include 3/4 to 1-ton trucks from various vehicles, including Ford, Chevy, GMC, Dodge and Jeep. Generally, large trucks use the stronger 8-lug wheels to incorporate larger brakes and improve stopping ability.


Wheel torque determines how fast a car can reach a particular speed. The higher the torque, the faster the acceleration. The units of torque are pounds per feet.


Net torque is the sum of all the individual torques acting on an object. Torque measures how much rotation-causing force is acting on an object. If the sum of all the torques is zero, the object is in rotational equilibrium.


AutoZone, Brandsport, Gorilla Automotive Parts and other auto parts retailers sell lug nut keys for locking lug nuts. Aside from more standard locking lug nuts, Gorilla and McGard sell specialized locking lug nut sets. To replace these keys you need to provide the wheel lock key registration number.


Online resources such as WheelLugPattern.com and Discounted Wheel Warehouse are useful in determining the wheel lug patterns of various car models. The wheel lug pattern refers to the number of bolts on car wheels and the distance between the bolt holes.


A torque converter is used in vehicles with automatic transmissions to connect the transmission to the engine. The converter transfers movement from the engine to the wheels and allows the engine to continue working slowly when the vehicle is stopped.


To measure a lug pattern, find the bold circle diameter, or BCD, and add the number of bolts to the diameter. Use a tape measure to complete this task.


The torque settings for cylinder head bolts are the manufacturer's recommendation for how tightly the bolts holding the cylinder heads to the engine block should be fastened. This is done using a special tool called a torque wrench that measures the pressure as the bolts are tightened.


The torque converter is located near the car's engine. The part has four main components – the pump, the turbine, the stator and the transmission fluid – which are connected to various parts of the engine.
