The rear leaf spring on the Ford f250 consists of two hangers and a system of U bolts that hold the spring to the rear axle. The hanger bolts that connect the spring to the shackle torque down to 185 ft-lbs. The shackles then bolt to the frame of the vehicle with 185 ft-lbs. Once the leaf spring is connected to the vehicle the U Bolts can be used to connect the axle to the springs. The U bolts also torque down to 185 ft-lbs along with the rest of the leaf spring system.

Rear Axle Driveshaft Installation

The rear axles on the f250 are assembled from the side of the vehicle. In the center of the wheel there are several bolts that retain the axle inside. With these bolts removed the axle can be removed from the vehicle and access to the rear end wheel bearing is given. These bearings are pressed into place and will need to be pulled out to be replaced. To reinstall the axle you just put it back in place and torque the retaining bolts to 76 ft-lbs.

Rear Differential Fluid change

Ford f250 rear end fluid change
The first step in replacing your rear end differential fluid is to jack the rear end of the vehicle up into the air. Be sure to use safety precautions so that no injuries occur. With the vehicle in the air you will have clear access to the rear differential. If you want to check the current fluid level you can pop off the rubber plug, if the level is full the fluid should be directly below the level of the plug. If it is lower then your are currently low on fluid. To replace the fluid inside the diff you must remove the plate and allow for the fluid inside to seep out. Be sure to have a container to catch the fluid. Once the fluid stops flowing you can reinstall the plate by using some silicone sealant to help prevent leakage. The bolts for the plate should be torqued to 30 ft-lbs. With the plate reinstalled you can now take your new fluid and fill the rear end up through the rubber plug hole. Once done reinstall the plug and ensure that there are no leaks.
