Unlocking the Secrets to Troubleshooting Your Ford F-250 Super Duty Locking Hub
Locking hubs are a common accessory to most 4-wheel drive vehicles such as the Ford F-250 Super Duty. It basically allows any off-roader to take control of the front wheels independently to better maneuver it in difficult terrain. Due to the pressure off-road vehicles usually put on their locking hubs, they are prone to abuse and damage. Know exactly when that happens with these troubleshooting tips to common problems experienced with a Ford F-250 Super Duty locking hub.
4-wheel drive that doesn't engage
Once the 4-wheel drive function won't engage, it's about time you check on the health of the Ford F-250 Super Duty locking hub. Locking hubs are generally in charge of switching your truck's drive system from the normal 2-wheel drive to the more powerful 4-wheel drive. So when you feel like your pickup truck's front wheels won't pull even after engaging its 4-wheel drive, be sure to visually inspect its locking hub. Watch out for broken hub surfaces, chips, and rust. This could all lead to a damaged hub and eventually a 4-wheel drive that doesn't engage properly.
Locking hubs that won't unlock
While failure of locking hubs to engage is common, a hub that won't unlock is a rare, and dangerous, case. That is why they should be inspected at the first signs of failure. The most noticeable sign of a locking hub that won't disengage is a loud popping noise coming from the hub. Also while driving, be sensitive to the wheel's movement while on the road. If it feels like you're driving with the 4WD in motion even if it isn't, you should inspect if your locking hubs are still responsive by physically turning the front driveshaft and wheels.
Grinding or slipping noise
Whenever your hubs fail to engage, another problem you'll experience is an uncomfortable grinding noise coming from under your truck. When this happens it's a good idea to check your vehicle's locking hubs for a possible loose bearing. To check this, jack up your car and access the wheel's front driveshaft. Get a feel of its grip and whether or not it is too tight on the wheel. When spun, the wheels should turn freely.
