What is wheel torque? A rotational force given in foot-pounds (ft-lbs), wheel torque measures lug nut tightness. And it’s critical to safely installing your wheels. Every vehicle has its own torque requirements.
What torque should lug nuts be?
Under- or over-tightening wheel-attaching hardware can be damaging and dangerous.
| Hardware Bolt or Stud Size | Typical Torque Range in Ft/Lbs | Minimum Number of Turns of Hardware Engagement |
|---|---|---|
| 12 x 1.5 mm | 70 – 80 | 6.5 |
| 12 x 1.25 mm | 70 – 80 | 8 |
| 14 x 1.5 mm | 85 – 90 | 7.5 |
| 14 x 1.25 mm | 85 – 90 | 9 |
What does it mean to torque your lug nuts?
Lug nuts keep a wheel securely attached to the hub—which means they are an extremely important component of a vehicle.Torque is the amount of force someone applies to a lug nut when they’re tightening it.
What is the torque spec?
By definition, torque refers to the amount of rotational force at the point of application. When attaching a wheel to a vehicle, torque specifications are the amount of force recommended on the hardware to ensure proper installation.
Where do I find torque specs on my car?
Where To Find The Correct Manufacturer Recommended Torque Specs. The torque specs for the axle nut (and other nuts and bolts) should be listed in the dealership/shop guide provided by the manufacturer. If you can’t find that information, or if you don’t have a guide, you can find the specs in the service manual.
How often do lug nuts need to be replaced?
Companies claim that it is difficult to plan a vehicle’s route that will bring it to a location where this work can be done to meet the specified distance.” And of course wheel nuts should be re-torqued at regular maintenance intervals or every 10,000 miles to account for any changes in clamping force.
Is torque check necessary?
Checking for loose lug nuts
Torque is the unit of measurement for the twisting force that’s applied to a lug nut. Mechanics will ensure that each lug nut has been torqued to the vehicle manufacturer’s specifications when first fitting a wheel. But a second follow-up check is also necessary.
Can you over tighten lug nuts?
Excessively tightened lug nuts can strip the threads, distort brake rotors, damage the wheel, and possibly shear off the lug stud. Insufficiently tightened lug nuts can come loose, with catastrophic consequences.
What happens if you don’t torque to spec?
Insufficient torque
Alternatively, the engine’s vibrations can cause the bolt or nut to come undone, displacing the tensioner. This, in turn, will lead to incorrect belt tension and, eventually, to belt and/or engine damage.
What is the torque for 5/8 Grade 8 bolt?
US Recommended Bolt Torque
| Size | Recommended Torque | |
|---|---|---|
| Grade 2 | 18-8 S/S | |
| 5/8″ | 73 | 93 |
| 3/4″ | 125 | 128 |
| 7/8″ | 129 | 194 |
Do mechanics use torque specs?
Dealer mechanics have service information for all the models they are required to repair under warranty, which includes torque specifications.
What are the torque specs for transmission pan?
7 to 9 ft-lbs…..not much at all. DON’T over torque or you’ll screw up the pan gasket. Take your time, as it does require a bit of dexterity to hold the pan up, keep the gasket in place and tighten 21 bolts at the same time.
How much does it cost to replace lug nuts?
The Best in Auto Repair
The average cost for wheel lug stud replacement is between $73 and $89. Labor costs are estimated between $61 and $77 while parts are priced at $12. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
Is it necessary to replace lug nuts?
Any time you’ve had a tire change—whether it was done at a repair facility or at the roadside—you should get the lug nuts checked within about 100 kilometres of driving, to ensure they’re not too tight or too loose. This also applies after you’ve had your full set of tires changed for winter or in spring.
What happens if I don’t re torque my tires?
If the lug nuts are too tight, the bolt head can come off the lug nut. If they’re too loose, the bolts could fall out, and your tire could come off. While both scenarios are unlikely, they would both cause some serious damage if they were to occur.
Can I re torque my own tires?
Professional car mechanics can re-torque your tires, but if you prefer to take the DIY route, it can be done. You will most likely need to have a torque wrench that can identify how much force you’re using to avoid over or under-tightening the lug nuts.
How often should tires be rotated?
During rotation, each tire and wheel is removed from your vehicle and moved to a different position to ensure that all tires wear evenly and last longer. Tires should be rotated every six months or 6,000 to 8,000 miles.
How do you check torque on a wheel nut?
Attach each lug nut by hand, and then use a manual torque wrench to tighten until you hear the ‘click’ sound that indicates you’ve reached the right amount of torque. The number—usually in the 75-100 lb-ft range—should be easy to locate in your vehicle’s owner’s manual.
Can you hand torque lug nuts?
Buy a torque wrench if you are unsure of how tight they should feel without one. You tighten them up by hand as much as you can, then use the socket and wrench to tighten them – usually a quarter or half a turn and then they are TIGHT. Finger tight + 1/8th to 1/4th of a turn will get you out of trouble.
Should lug nuts be lubricated?
But experts tell us not to use any lubricant, including anti-seize compound, on wheel studs or nuts. The tech folks at Tire Rack state: “Torque specifications are for dry threads only. The fastener threads should be free of oil, dirt, grit, corrosion, etc. It is important NOT to lubricate hardware threads or seats.
Is it OK to not use a torque wrench?
It is useful to have, but not absolutely nessecary to work on a vehicle with. Keeping within torque specifications is important- if it isn’t tightened enough, the fastener could work itself loose during use and often with catastrophic consequences such as a wheel falling off at highway speeds.
