QU40143 Axle Shaft Support Bearing is a full complement Needle Roller Bearing for all Dana-Spicer Model 50 and Model 60 front drive axles in 1999-2004 Ford Super Duty® and 2000-2005 Ford Excursion 4x4 front wheel hubs.

Applications

Tech Note 1: Puller
Use a blind hole bearing puller to remove the old bearing from your wheel hub.

Tech Note 2: Worn Bearing
A worn Axle Shaft Support Bearing will almost always chew up the matching axle shaft bearing surface. So if you need a bearing, chances are you also need a QU40318 axle shaft.
