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.
The torque specifications for an axle nut depends on the application of the axle nut and can vary slightly from company to company. The factory manual for the vehicle likely mentions the axle nut specification.
A wheel lug nut torque chart indicates the proper amount of torque, or twisting force, to apply to the lugs nuts found on vehicle wheels. Mechanics need to apply proper torque when tightening lug nuts to ensure damage does not occur to the wheels.
To torque a wheel, one should have a jack and a torque wrench. Though not efficient, a lug wrench can also be used to torque a wheel. If properly torqued, a vehicle has minimal risks of brake damage, stud distortion and eventual wheel loss.
The website Tork Spec allows users to access torque specifications for a variety of cars sold in the United States. It has a broad collection of torque specifications, including both engine torque specifications and model torque specifications.
Users can find torque specs for certain wheels at the Dorman Products wheel nut torque specifications document or at the Discount Tire wheel torque chart webpage. The two mentioned documents are not exhaustive, however. Torque specs for wheels of newer car models may not be available.
The torque specifications for a front-axle wheel bearing varies according to the type of vehicle it applies to, however it ranges on average between 15 and 20 ft-lbs. Most of the torque is directed to the axle nut, which mounts on top of the hub assembly and can range up to 200 ft-lbs.
Some tips for wheel bearing torquing include using a torque wrench instead of an impact wrench and checking for the recommended torque procedure before starting. Also, do not reuse the old nut and clean the axle shaft before installing.
To find out a wheel torque spec, check the vehicle's manual, industry reference guide or the shop repair manual. Vehicle dealers can also provide an appropriate wheel torque spec.
Torque in cars is a measure of how much turning force the engine can provide, which indicates how fast the car can accelerate. Cars with more torque have an easier time reaching higher speeds, towing heavier loads, moving from stand-still and climbing hills.
