How To Take Off Spare Tire Under Truck | Drop It Safely

A truck’s underbody spare usually comes down with a crank tool through a rear access hole, then slips free from the carrier cable.

If your spare tire hangs under the bed, the job is usually simple once you find the access point and line up the tool the right way. The snag is that trucks don’t all use the same carrier. Some have a plain cable hoist. Some add a lock or retaining plate. Some hide the access tube near the license plate, while others tuck it above the rear bumper.

This walk-through shows the usual process, the hang-ups that slow people down, and the checks to make before you put the spare on the truck. Read it once before you start. That saves crawling in and out from under the rear end five times with dirty hands.

Before You Crawl Under The Truck

Start with the truck on flat, solid ground. Set the parking brake. Put the transmission in park, or in first gear if it’s a manual. If you have wheel chocks, wedge the wheel on the side that stays on the ground. If you don’t, a solid block can help keep the truck from rolling.

Then grab the tire tools. On most pickups, the jack handle, extension rods, and lug wrench sit behind a rear seat, under a seat base, or near the jack storage tray. Pull them out and test-fit the pieces before you get under the truck. A loose rod connection makes the hoist feel stripped even when it’s fine.

What You’re Trying To Find

  • The spare tire access hole near the bumper or plate bracket
  • The crank rod or extension pieces that reach the hoist
  • The locking plate, cable end, or keeper that holds the wheel once lowered
  • Enough slack under the truck to tilt the tire and slide it out

What Not To Do Yet

Don’t jack the truck up just to remove the spare. The spare drops from its carrier with the truck sitting on the ground. Raising the truck first adds wobble and steals working room. Save the jack for the flat corner after the spare is out and ready.

How To Take Off Spare Tire Under Truck On Most Pickups

The usual carrier is a cable hoist. A metal cable runs down through the wheel center and holds a plate on the bottom side of the rim. When you turn the crank, the hoist winds the cable down and the spare drops toward the ground.

  1. Find the access hole. It may sit above the rear bumper, beside the license plate, or through a small round guide tube under the tailgate area.
  2. Assemble the tool. Join the extension rods and attach the crank end or lug wrench as your truck’s kit requires.
  3. Feed the tool into the guide tube. Push until you feel it seat into the hoist drive. If it slips, pull back and try a straighter angle.
  4. Turn the tool to lower the tire. Most carriers unwind with counterclockwise turns, though some trucks vary. The spare should begin dropping after a few turns.
  5. Lower the tire all the way to the ground. Keep cranking until the cable goes slack. You want enough slack to tilt the wheel by hand.
  6. Pull the tire out from under the truck. Drag it toward the rear or side, whichever gives you room.
  7. Turn the tire on its side. Reach through the wheel center, tip the retaining plate, and slide it through the center hole.
  8. Free the cable and plate. Once the plate clears the wheel, the spare is off the truck.

If the spare won’t move after the first few turns, stop and check tool alignment. Most “stuck” spares aren’t stuck at all. The crank rod just isn’t fully seated in the hoist head.

How To Tell You’re Doing It Right

You should feel steady resistance, not a skipping or grinding feel. The tire should come down in a straight line. If one side hangs up, the wheel may be wedged against the heat shield, hitch hardware, or a bent carrier bracket. A small tug on the tire while the cable is slack can free it.

Truck makers place the spare in a few different spots. Ford’s spare tire location notes show that some models store it under the rear of the vehicle, while others put it inside the cargo area. Your owner’s manual gives the exact access point and tool order for your truck.

What Usually Stops The Spare From Coming Down

Road grime, rust, and carrier neglect cause most trouble here. Underbody spares live in spray, salt, dust, and mud. If the tire hasn’t been lowered in years, the hoist or plate can bind. This table shows the snag and the fix that usually works.

Problem What It Feels Like What To Do
Tool not seated Crank spins or skips with no tire movement Pull the rod out, line it up straighter, and seat it again
Carrier lock fitted Tire lowers a little, then stops Use the lock adapter or spare tire key from the tool kit
Rusty hoist Heavy drag all the way down Lower in short turns, add penetrating oil at the hoist, then work it slowly
Cable twisted in wheel Tire hangs crooked Lower fully, tug the tire flat, then feed more slack
Retaining plate jammed Cable is slack but plate won’t pass through rim Stand the tire on edge and rotate the plate sideways through the center hole
Wheel packed with mud Plate and cable won’t clear the center Knock mud out of the center hole before tilting the plate
Spare pressed into hitch gear Tire drops partway, then binds Pull the tire rearward while lowering to clear the obstruction
Damaged hoist Clicks, binds, or stops hard Stop cranking; forcing it can snap the cable or strip the hoist

Carrier Types And Model Differences That Matter

Not every truck uses the same wheel retainer. Many use a simple oval or rectangular plate on the cable end. Some use a wider keeper that only fits through the wheel center at one angle. Trucks with alloy spare wheels may feel tighter than steel ones, since the plate has less wiggle room as it passes through the opening.

Trucks With A Spare Tire Lock

Some pickups add a lock between the access tube and the hoist. If your crank tool won’t engage at all, check the kit for a keyed adapter. Without that piece, the rod won’t bite into the mechanism. This is common on trucks that came with theft-deterrent gear from the factory.

Trucks With A Stuck Secondary Catch

A few carriers have a secondary catch that holds the spare after the hoist drops. If the tire lowers but still won’t release, lift it slightly by hand, shake it, and lower it again. The catch may need that little reset before it lets go.

Once the spare is free, give it a quick check. Tread matters, but air pressure matters just as much. An underbody spare can lose pressure over time and still look fine. NHTSA tire safety guidance is a good reminder to check pressure against the door placard, not by eye.

When To Stop And Get Help

Sometimes the spare carrier is too rusted, bent, or seized to trust on the roadside. If any of the signs below show up, stop before you turn a simple tire swap into a broken hoist, a snapped cable, or a truck stuck on a jack with no spare ready.

Warning Sign Why It Matters Next Move
Cable frays or kinks The carrier may fail when rewound Use roadside service or a shop
Hoist clicks hard and locks The gear may be stripped Stop cranking and get the hoist checked
Retainer plate is bent The spare may not mount back in place Remove the tire, then replace the plate
Spare has sidewall cracks The tire may not be roadworthy Use a tow or fit a full-size replacement
No tool kit or lock key You may not be able to drop the tire Check storage areas, then call for help

After The Spare Is Off The Truck

Before you bolt the spare onto the hub, compare it with the flat tire. Check diameter, bolt pattern, and sidewall markings. Many trucks carry a temporary-use spare, while others carry a full-size wheel. If it’s a temporary spare, speed and distance limits apply, and those limits are printed on the tire itself.

Then set the flat tire aside where it won’t roll. When you’re done with the tire change, rewind the empty cable partway so it doesn’t drag. Once the repaired wheel goes back under the truck, feed the retaining plate through the wheel center, hold the tire flat, and crank it snug against the underbody. Don’t leave it loose. A spare that swings around under the bed can damage the hoist, the wheel, or the truck floor above it.

A Simple Habit That Saves Trouble Later

Drop the spare once or twice a year, even if you never need it. That one habit keeps the hoist moving, lets you spot a soft spare before a roadside flat, and makes the real job feel familiar when you’re doing it on a dark shoulder.
