Spare Tire and Wheel

More Information

The spare tire system on most trucks, SUVs, and vans stores the full-size or compact spare underneath the vehicle, suspended by a cable-and-winch hoist assembly. Over time, the hoist cable corrodes, the winch mechanism seizes, and the lock cylinder tube rusts through — leaving you unable to lower the spare when you actually need it. The jack handle and lug wrench that engage the hoist are equally failure-prone, bending or snapping under torque. When replacing a hoist, confirm the cable length and drum diameter match your vehicle's bed or frame mount — these specs vary significantly between model years, especially on Ford F-Series, GM Sierra/Silverado, and Ram 1500 trucks. OEM hoists ensure exact fit and load ratings; aftermarket units from Dorman or Crown are widely available and cost considerably less, though quality varies. Access hole covers are often overlooked but prevent water intrusion that accelerates hoist corrosion.

Signs you need replacement

• Spare won't lower to the ground. If turning the jack handle produces no movement or the cable feels locked, the hoist winch has likely seized from corrosion — common on vehicles over 6–8 years old, especially in rust-belt states.
• Cable frays or snaps when lowering the spare. A broken or kinked hoist cable means the spare can drop suddenly or not lower at all; the cable alone is not serviceable on most assemblies, requiring full hoist replacement.
• Jack handle or lug wrench spins freely without engaging. The hex socket or drive end of the handle wears down or deforms over time, especially if the hoist was last operated with a corroded tube — replace before your next roadside emergency.
• Spare tire drops or sits visibly low under the truck. A stretched cable, worn retainer, or failed hoist bracket allows the spare to hang unevenly, risking road contact at speed or loss of the tire entirely.
• Missing or cracked access hole cover. The plastic cover over the hoist access point in the truck bed cracks with UV exposure and age, letting water funnel directly onto the hoist mechanism and accelerating rust.
• Spare carrier rattles or clunks over bumps. A loose or cracked hoist lock cylinder tube allows the spare to shift in its cradle, which can damage the tire sidewall and indicates the retention hardware has failed.

Frequently asked questions

• How often should a spare tire hoist be inspected or replaced? Inspect the hoist cable and winch mechanism every 2–3 years or any time you rotate tires. Most hoists don't fail on a schedule — they fail from corrosion and neglect. Proactive replacement is recommended on trucks older than 10 years that have never had the hoist serviced, particularly in high-moisture or salt-road environments.
• Is an OEM spare tire hoist worth it over an aftermarket unit like Dorman? OEM hoists offer guaranteed fit and cable load ratings matched to your vehicle's spare tire weight. Dorman and similar aftermarket units typically cost 30–50% less and fit most applications well, but verify the part number against your year, make, model, and cab/bed configuration — some platforms have multiple hoist variants within the same model year.
• What does a spare tire hoist replacement cost, and is it a DIY job? Parts range from $35–$120 for most aftermarket hoists; OEM units run $80–$200. The job is DIY-friendly in 30–60 minutes — you'll need the factory jack handle or a 1/2-inch ratchet extension to wind the new cable down. Replace the lock cylinder tube and access cover at the same time to prevent repeat failures.
