What is the torque on the axle bolts on a Ford e350?
The torque on the axle bolts of a Ford E350 van is an important factor in ensuring the vehicle's safety and proper operation. Proper torque ensures the axle is securely attached to the vehicle, preventing potential issues like wheel separation or uneven tire wear. Let's dive into the details of determining the correct torque for the axle bolts on a Ford E350.
Recommended Torque Specifications
According to the Ford E350 service manual, the recommended torque for the axle bolts on this vehicle is 250-300 ft-lbs (339-407 Nm). This torque range is critical to maintain the proper clamping force on the axle, which helps prevent the bolts from loosening over time due to the vibrations and stresses experienced during normal driving.
Importance of Proper Torque
Maintaining the correct torque on the axle bolts is essential for several reasons:
- Wheel Stability: Proper torque ensures the axle is securely attached to the vehicle, preventing the wheel from becoming loose or separating, which could lead to a dangerous situation.
- Tire Wear: Uneven torque can cause the axle to be misaligned, leading to uneven tire wear and reduced vehicle handling and stability.
- Safety: Loose or improperly tightened axle bolts can result in a catastrophic failure, putting the driver, passengers, and other road users at risk.
It's crucial to follow the manufacturer's recommended torque specifications and regularly inspect the axle bolts to ensure they remain within the proper range.
Checking and Adjusting Torque
To check and adjust the torque on the axle bolts of a Ford E350, follow these steps:
- Park the vehicle on a level surface and apply the parking brake.
- Loosen the axle bolts, but do not remove them.
- Using a torque wrench, tighten the bolts to the recommended torque range of 250-300 ft-lbs (339-407 Nm).
- Recheck the torque on all bolts to ensure they are within the specified range.
- If any bolts are not within the range, loosen and retighten them to the proper torque.
It's important to follow the manufacturer's guidelines and use the correct tools to ensure the axle bolts are tightened to the proper specification. Regularly checking and maintaining the axle bolt torque is essential for the safe and reliable operation of your Ford E350.
What is the torque on the E450 axle bolt?
For the rear axle hub nut on a Ford E450, it's generally advised to apply a torque between 200 to 220 foot-pounds. Once this initial torque is achieved, continue tightening until the next castellation is reached, ensuring not to surpass a total of 275 foot-pounds.
What is the torque on a thru axle bolt?
How tight should my thru axle be? Typically, thru axles should be tightened to 12-15Nm (Newton Meters) of torque. This is just enough torque to secure the axle so it does not come loose while riding. You should never tighten your axle as tight as possible.
What is the torque spec of the Ford F350?

Yet, it's the two turbo diesel choices that dominate with their impressive torque figures — an impressive 1,050 pound-feet for the standard-output Power Stroke turbo diesel and a staggering 1,200 pound-feet for the high-output version.
What is the torque specs for a axle nut?
On some wheel bearings sets and hub units, the axle nut secures the outer flange to a CV joint or stub axle. As the nut is tightened, it pulls the flange and axle together to set the preload of bearings. These axle nuts will have specifications as low as 130-foot pounds and as high as 300-foot pounds.
