GMB 720-0021 front wheel bearing and hub assembly for the 1999-2008 Mitsubishi Galant and other vehicles carries the wheel and lets it turn. Like other GMB wheel bearings, it is preloaded to reduce excess noise and vibration.
A humming or grinding noise that changes with speed, or vibration from one wheel, can mean the bearing is worn. These signs alone do not prove the bearing is the problem, since an out-of-balance tire can cause similar vibration.
It works as a wheel bearing for the 2001-2005 Dodge Stratus and the 1995-2005 Chrysler Sebring, and it is listed for a wide range of Mitsubishi, Chrysler, Dodge and Eagle models. Either car takes two, one per front wheel. This listing is one assembly, and the front pair is normally replaced together. GMB builds it to OEM specifications or better. If your car is not named here, find it in the "Vehicles it fits" section.
