Where to Put Jack on F150 Rear: What to Know and Why It Matters
For most Ford F-150 models, place the jack under the rear axle tube near the wheel you need to remove, not under the differential cover or the thin axle housing. The exact approved point can vary by model year and jack type, so confirm the location in the owner’s manual before lifting.
A solid thump, a jack that leans, or an axle that starts shifting sideways is a warning to stop rather than keep pumping. By contrast, a small change in suspension height as the tire leaves the ground is normal; the important distinction is whether the truck remains stable and the jack saddle stays centered on a strong, flat section of the axle.
This guide explains where to position a factory or floor jack, why the rear axle tube is usually the correct support point, which nearby components can be damaged, and how to secure the truck before removing a wheel. You will also learn how 2WD and 4WD setup, aftermarket equipment, uneven ground, jack stands, and a loaded bed can change the safest approach.
The Correct Rear Jacking Point on an F-150
When lifting one rear wheel, position the jack beneath the rear axle tube on the same side as the wheel being serviced. Choose a substantial, round section of the axle housing between the wheel and the differential, keeping the saddle as close to the wheel as practical without touching the brake assembly, shock absorber, or suspension linkage.
The axle tube is designed to carry the rear suspension and wheel loads. It provides a strong lifting surface, while the jack saddle helps spread the force across the housing. Lifting near the wheel also raises that corner more directly and reduces unnecessary suspension movement.
Do not automatically place the jack beneath the center differential. The differential housing may look like the strongest point, but the cover, drain plug, or irregular casting may not provide a secure, level contact area. A poorly centered jack can slip, bend a cover, damage a seal, or lift the truck unevenly.
Some F-150 owners use the axle housing to lift both rear wheels at once, but that should only be done when the jack, surface, and vehicle setup are appropriate and the owner’s manual permits it. For a roadside tire change, lifting the affected side at the approved axle point is generally the more controlled method.
What to Avoid Under the Rear of the Truck
The rear axle has several components that look convenient but are not intended to be jack contact points. Avoid placing the jack on the differential cover, rear brake rotor, brake backing plate, shock absorber, sway-bar hardware, exhaust parts, fuel tank, or thin suspension brackets.
Never use a plastic or stamped cover as the lifting surface. Even if it supports the differential lubricant, it may deform under concentrated jack pressure. Damage can lead to a fluid leak, contamination, or a repair that is far more expensive than a tire change.
Keep the jack away from brake lines and cables. A line that is crushed or pulled may not fail immediately, but later braking problems can result. The jack should contact only a strong structural surface that the truck manufacturer identifies or that clearly forms part of the axle housing.
On trucks with aftermarket lift kits, lowered suspension, custom axle trusses, traction bars, air bags, or non-factory shock mounts, the original contact point may be difficult to reach or may have changed. In that situation, use the equipment instructions and the vehicle-specific service information rather than guessing from the factory arrangement.
How to Position the Jack Safely
Before reaching under the truck, move it onto firm, level ground whenever possible. Asphalt or concrete is preferable to soft soil, gravel, a sloped shoulder, or a surface that can allow the jack wheels to sink or roll unpredictably.
- Park the F-150, switch off the engine, apply the parking brake, and place the transmission in Park. Follow the owner’s manual if it gives different instructions for a specific drivetrain or emergency procedure.
- Turn on the hazard flashers if the truck is near traffic, and place warning devices where appropriate. Do not attempt a wheel change in an unsafe travel lane when a safer location is available.
- Block the wheel diagonally opposite the corner being lifted. For a right-rear tire, chock the left-front wheel; for a left-rear tire, chock the right-front wheel.
- Remove the spare tire and jack tools before lifting if the spare is stored beneath the truck. Keep the ground clear so the jack handle cannot be knocked or caught.
- Loosen the wheel nuts slightly while the tire is still on the ground. Do not remove them yet.
- Slide the jack under the rear axle tube near the affected wheel. Center the saddle on the tube and make sure the jack stands upright with its wheels or base fully supported.
- Pump or turn the jack slowly until the saddle contacts the axle. Recheck that it has not shifted, then raise only until the tire clears the ground.
- Remove the wheel nuts and wheel. After the replacement wheel is installed, lower the truck carefully and tighten the nuts in the prescribed pattern and torque.
The jack should remain nearly vertical as it rises. A hydraulic floor jack may roll slightly as its arm lifts, which is normal when the wheels are free to move on a hard surface. A scissor jack should remain stable and upright; if it tilts, stop lowering the truck and reposition it.
Factory Jack Versus a Floor Jack
The F-150’s supplied emergency jack is intended for a tire change, not for supporting the truck during repairs. Its lifting capacity and contact shape are matched to the vehicle’s approved points, but it still requires level ground and careful positioning.
A floor jack can be more stable and easier to operate, especially in a garage, but its saddle must fit the axle tube without crushing wiring, brake components, or other parts. Check the jack’s rated capacity against the truck’s weight, particularly if the bed contains tools, cargo, or a camper setup.
Do not place a small piece of loose wood between the jack and the axle unless the equipment or vehicle instructions specifically support that arrangement. Wood can split, slide, or change the saddle’s grip. A purpose-made rubber saddle adapter may improve contact, but it must remain securely seated and must not prevent the jack from supporting the axle correctly.
A jack is a lifting device, not a long-term support. Once the truck is raised, install jack stands at manufacturer-approved support points before working beneath it. Never crawl under an F-150 supported only by a hydraulic jack or emergency scissor jack.
Why the Rear Axle Point Is Usually Preferred
The rear axle carries the rear wheels, differential, and part of the truck’s suspension load. When the jack lifts the axle tube, the corresponding wheel rises as the suspension compresses or unloads, giving the jack a direct path to the tire that needs to come off.
Using the axle tube also avoids placing force on parts that are designed to locate, damp, or protect the suspension rather than carry a concentrated lifting load. This is why the correct position is usually a reinforced axle section rather than a nearby frame edge or suspension arm.
The precise location still matters. Placing the saddle too close to the outer end can interfere with the wheel, brake assembly, or backing plate. Placing it too far inward can lift the differential side of the axle, produce more suspension movement, or leave the saddle on an uneven transition in the housing.
Look for a firm, clean area of the tube. Dirt, rust scale, or an oily surface can reduce grip and hide damage. Wipe away loose debris, but do not scrape away structural metal or attempt a roadside repair on a badly corroded axle.
Important Conditions That Change the Procedure
Loaded bed or trailer
Remove unnecessary cargo before lifting when it can be done safely. A heavy load changes the force on the axle and may exceed the practical capacity of a roadside jack, especially if the truck is carrying equipment, a slide-in camper, or tongue weight from a trailer.
Do not use a small vehicle jack to lift a truck while a trailer remains attached unless the manufacturer specifically permits that procedure. The trailer can shift, add load, or affect the truck’s stability.
Uneven or soft ground
If the shoulder is soft, the jack may sink while the tire is off the ground. A wide, rigid base can help only if it is suitable for the jack and remains flat; improvised materials may crack or slide. Move to a firm location or call for roadside assistance when the surface cannot support a stable lift.
Four-wheel-drive and electronic systems
Four-wheel-drive equipment does not usually change the basic rear axle lifting point, but it can change how the truck reacts when a wheel is raised. Follow the owner’s manual for transmission position, drivetrain controls, and any required traction-control settings.
Do not rely on four-wheel drive, the parking brake, or an electronic system to prevent movement while the truck is supported. Mechanical wheel chocks and a stable lifting surface remain essential.
Rust, damage, or a leaking axle
A heavily rusted axle tube, bent housing, leaking differential, or damaged suspension component may not safely support a jack. If the saddle cannot sit flat on sound metal, stop and arrange professional assistance.
A clicking jack, sudden drop, fluid leak, or visible bending is also a reason to lower the vehicle if it can be done safely. Do not place any part of your body beneath a truck that is moving or unstable.
After the Wheel Is Installed
Install the wheel with the mounting surfaces clean and the nuts started by hand. Lower the truck until the tire contacts the ground enough to prevent rotation, then tighten the nuts in a star or crisscross pattern.
Use a calibrated torque wrench and the wheel-nut torque listed for the specific F-150 in its owner’s manual. Torque values can differ by model year, wheel design, and fastener setup, so do not substitute a generic truck specification.
Retrieve the jack, chocks, and tools before driving away. Check that the spare or repaired tire has appropriate inflation, then recheck the wheel-nut torque after driving the distance and under the conditions specified by the vehicle documentation or tire service provider.

FAQ About Where to Put Jack on F150 Rear
Where should a jack go on the rear
Place it under the rear axle tube near the wheel being removed. Keep the saddle on a strong, clean section of the axle housing and follow the model-specific owner’s manual for the final position.
Can I put the jack under the F-150 rear differential?
Do not use the differential cover as a jack point. The center housing may have an approved lifting area on some setups, but the cover and drain plug are poor contact surfaces, so the axle tube is normally the safer choice for a single rear wheel.
Can I jack up both rear wheels from the center?
Only do this when the jack and vehicle instructions approve the method. A center lift requires a properly rated jack, a stable surface, and enough clearance to keep the entire truck secure; lifting one side at the axle tube is usually more controlled for a tire change.
Can I use the rear frame as a jack point?
Use the frame only where the F-150 manual identifies an approved support point. A convenient-looking frame edge may be thin, obstructed, or unsuitable for a floor-jack saddle, while the rear axle tube is generally better for raising a rear wheel.
Should I use jack stands after lifting the rear?
Yes, use jack stands before doing work beneath the truck. The factory jack is for lifting and changing a tire, not for holding the vehicle while a person works underneath it.
What if the jack keeps slipping off the axle?
Lower the truck and correct the setup before trying again. Confirm that the surface is firm and level, the saddle is centered on clean axle metal, and the jack is upright; call for assistance if corrosion, modifications, or limited roadside space prevents a secure lift.
Conclusion: Use the Axle Tube and Keep the Lift Controlled
For most F-150 rear tire changes, the practical answer is to place the jack under the solid rear axle tube close to the wheel being serviced. Avoid the differential cover and nearby brake or suspension components, secure the truck with chocks, and raise only as much as needed.
The major limitation is that model years, aftermarket modifications, vehicle load, and ground conditions can change what is safe. Check the owner’s manual, use jack stands for under-truck work, and choose roadside assistance instead of guessing when the jack will not sit securely.
