The front outer wheel bearing sits in the wheel hub and lets the wheel rotate on the spindle while carrying the loads placed on that corner of the truck. If you are replacing Timken front wheel bearings on one of these Dodge trucks, signs that a bearing may need replacing include a growling or grinding noise that changes with road speed, play or looseness at the wheel, and roughness when the wheel is spun by hand. These symptoms can have other causes, so diagnose the wheel end before you replace parts.
