The rear suspension on your Ford F-150 truck consists of leaf springs that mount above the rear axle at each side of the undercarriage. Each leaf spring is secured to the axles with a pair of U-bolts. Each end of the individual leaf springs connects to spring brackets at the front and rear of that spring. The brackets extend below the frame of the truck, making them vulnerable to damage when driving off-road or maneuvering over obstacles on job sites. Factory and aftermarket rear spring brackets for Ford F-150 trucks are available through many parts outlets.
Things You'll Need
- Replacement bracket
- Wheel chocks
- Floor jack
- Jack stands
- Hydraulic jack
- Socket and ratchet
Chock the front tires of the truck securely with wheel chocks or wood blocks. Roll a floor jack under the rear differential of the truck. Raise the jack enough to install jack stands under the rear axle, between the differential and leaf springs at each side.
Position a one-ton hydraulic jack under the leaf spring near the end where the bracket needs to be replaced. Center a small wood block atop the piston on the jack. Raise the jack under the leaf spring to the point where the jack is secure under the lower leaf.
Remove the hanger bolt and nut that holds the end of the leaf spring to the bracket using a socket and ratchet. Set the bolt and nut aside for re-installation.
Loosen and remove the bolts that hold the upper ends of the spring bracket to the truck frame. Save the bolts and nuts and remove the bracket.
Position the new spring bracket at the truck frame, making sure the holes for the hanger bolt face the end of the leaf spring. Attach the bracket using the saved bolts and nuts, and tighten the nuts with the socket and ratchet.
Raise or lower the hydraulic jack as needed to align the holes for the hanger bolt in the new bracket with the end of the leaf spring. Install the saved bolt and tighten the nut with the socket and ratchet.
Lower the hydraulic jack and slide it out of the away. Raise the differential with the floor jack and remove the jack stands. Lower the truck and pull the floor jack out of the way. Remove the wheel chocks at the front tires.
Tips & Warnings
- The front and rear brackets and leaf springs differ on some trucks. Specify the location and width of leaf springs when obtaining brackets.
- Use an open-end wrench to back up nuts when loosening and tightening bolts.
