Dorman - OE Solutions Air Suspension Spring P/N:949-824
Help your rear suspension hold proper ride height with the Dorman - OE Solutions 949-257, a direct-fit Lincoln Navigator air spring for 2003-2006 models that also fits the 2003-2006 Ford Expedition. It installs at the rear of the vehicle and fits either the left or the right side.
An air spring holds pressurized air from the air suspension system to help support the vehicle and keep it at its intended height. When the original unit leaks, that corner can sit low and the compressor may work harder to make up the lost air.
Signs a suspension air spring may need replacing include a rear corner that sags after the vehicle sits, an audible air leak, a compressor that runs more often than usual, or a suspension warning message. Leaking air lines and other system parts can cause similar symptoms, so diagnose the cause before replacing the spring. Replacing the left and right rear springs together is recommended to help keep ride height even. See the Buyer's Guide tab for complete application details.

Does this 2003-2006 Ford Expedition air spring also fit the 2003-2006 Lincoln Navigator?
Yes. The Dorman 949-257 is listed for the 2003-2006 Ford Expedition and the 2003-2006 Lincoln Navigator. See the Buyer's Guide tab for full application details.
Which position does the 949-257 install in?
It is cataloged for the rear and fits either the rear left or the rear right position. Replacing both rear springs together is recommended to help keep ride height even.
What does an air spring do?
It holds pressurized air supplied by the air suspension system to help support the vehicle and keep it at its intended ride height.
Why does an air spring fail?
This unit is intended to replace an original spring that failed because its internal rubber components tore or rotted, which can let air leak out.
Should I diagnose the problem before installing a new spring?
Yes. A sagging rear or a compressor that runs often can also come from leaking air lines or other air suspension parts, so confirm the spring is the cause first.
