Ford F-250 Super Duty Leaf Spring

The Main Causes Of Problems With Ford F-250 Super Duty Leaf Spring

When your car goes through irregularities on the road, its leaf springs are the ones that help minimize the jolt transference to the chassis. They are one of the reasons why you can drive your Ford F-250 on the road with smoothness and comfort. However, there are times when dirt and moisture can build up inside the leaf springs and cause problems. Here's a simple guide on how to detect problems in your Ford F-250's super duty leaf springs and the culprits behind them.

Center spring breakage

Breakage in the center spring is usually caused by loose U-bolts. That is why it's important to make sure that the U bolts are tight because loose U-bolts may cause the center bolt area to absorb the greatest stress. If this area gets solidly clamped against an axle pad, the middle of the spring will not be able to bend. To prevent breakage, do not forget to check if the middle of the spring is securely clamped to its correct position.

The vehicle leans to one side in the back

If you notice unevenness or tilting in your Ford F-250's body, this could be caused by a sagging leaf spring. Leaf springs get saggy overtime because its molecules realign due to the continuous and heavy weight placed on them while supporting the car. While leaf spring sagging can't be avoided, the best way to solve this problem is to check the clearance between the chassis frame and the shop floor at all times. For better accuracy, you may also check the tire inflation or the distance between the rim and the floor.

Annoying squeaking noises coming out from the rear of the vehicle

When you start hearing noises coming from the rear of your car, this could be caused by debris getting in between your vehicle's leaf springs. Always make sure that the leaf springs are free from dirt and moisture by using a pressure washer while cleaning it to get rid of the dirt stuck in it. It is also advisable to put grease and silicon spray lubricant on the leaves as well as the leaf spring bushings.
