Q: How to remove and install the rear leaf spring on a Ford F-250?
A: To remove the rear spring, raise the vehicle until the weight is off the spring but the tire is still touching the ground. Securely place the frame on jackstands. Remove the nuts from the U-bolts and drive the U-bolts from the U-bolt plate. If applicable, remove the auxiliary spring and spacer, as well as the ride height spacer on 4WD models. Remove the spring-to-bracket nut and drive the bolt out of the spring eye bushing. Remove the spring shackle bolt, holding the nut on the other side with a back-up wrench. Take out the spring and shackle assembly from the rear shackle bracket, and then remove the spring from under the vehicle. If the spring eye bushings are worn or damaged, they must be replaced by an automotive repair shop. To install the spring, position the rear of the spring in the shackle and install the upper shackle-to-spring bolt and nut. On 4WD models, install ride height spacers between the spring and axle. Position the front of the spring in the bracket and install the bolt and nut. Position the shackle in the rear bracket and install the bolt and nut. Place the spring on top of the axle with the spring lie bolt centered in the hole in the seat. If applicable, install the auxiliary spring and spacer. Install the spring U-bolts, U-bolt plate, and nuts. Lower the vehicle to the ground and tighten the U-bolt nuts, front spring nut and bolt, and rear shackle bolts and nuts to the specified torque.
