Applications

Tech Note 1: Taper
QU40577 is a bit shorter than the original Dana Bushing because it does not taper down to a knife edge like the original bushings. The shorter length means the Bushing is less likely to get wedged in the root of the tapered axle shaft hole.

Tech Note 2: Use with Studs
The idea of using a split taper bushing is to eliminate all axle shaft to fastener air gaps thereby minimizing the chance the fasteners loosen up and shear the studs under high load situations. Tapered Axle Shaft Bushings are ONLY used with studs.

Tech Note 3: Removal
To remove the wedges, they must first be loosened up by vibration so they can expand slightly. Typically, you take off the locking nuts (and washers if present). An air hammer or large hammer/punch combination is then used to apply impact force to the noncritical open areas of the axle shaft flange. Sooner or later, the impact vibration will loosen the tapered wedges which can then be removed with QT1060 or other suitable tool. Never apply impact force to the stud, bushing or lathe center hole of the axle shaft!

Tech Note 4: Rear Axle Use
The original equipment Tapered Bushing part number is QU42009. QU42009 is about 4/10" long and it is used for both axle shafts and Dana 44 closed knuckle steering arms. QU40577 is 5/16" long so it can ONLY be used for rear axle shafts. The steering arms used on Dana 44 closed knuckle front axles have a deeper bore compared to rear axle shafts. So if you need tapered wedge bushings for your Dana 44 closed knuckle steering arm, you need QU42009.
