About Used Back Doors
The back door, or liftgate, is the rear closure on SUVs, vans, and hatchbacks, and it carries glass, a latch, wiper, and often a wiring harness. A complete used liftgate saves swapping all of that after rear damage.
What a Back Door Does
The back door, also called the liftgate or tailgate on SUVs and vans, is the large rear closure that swings up or open. It typically holds the rear glass, the latch and lock, the wiper motor, defroster connections, and wiring for lights and cameras, and it mounts on gas struts or hinges.
Signs Your Back Door Is Failing
- Collision damage or dents from a rear impact
- Rust along the lower edge and around the glass
- Struts that no longer hold it up, or worn hinges
- Damage affecting the glass, latch, wiper, or wiring
What to Check When Buying a Used Back Door
- Decide between a bare liftgate and a complete one with hardware
- Check for rust at the lower edge and around the glass opening
- Confirm the latch, hinges, and strut mounts are sound
- Match the exact year range and the paint code
Common Applications
SUVs, vans, wagons, and hatchbacks all use a back door or liftgate. They are common rear-collision parts, and a complete used unit saves transferring the glass, wiper, latch, and wiring.

Frequently Asked Questions
What is the difference between a back door and a trunk lid?
A back door or liftgate is the tall rear closure on SUVs, vans, and hatchbacks that includes the rear glass, while a trunk lid or deck lid is the flat lid on a sedan's trunk. They are different parts for different body styles.
Should I get a complete liftgate?
If your glass, wiper, latch, and wiring are undamaged, a bare liftgate is cheaper. If the impact took those out, a complete used liftgate saves a lot of hardware transfer.
Why buy the whole liftgate used?
Because it carries so much: glass, wiper, latch, defroster, and wiring. A complete color-matched used unit can be far cheaper and easier than buying and installing all those pieces separately.
Will it match my paint?
With the correct paint code it will be close. A color-matched used liftgate usually blends well, with a blend or repaint available for a perfect match.
