Econoline E350 1 Ton V8-5.4L Prop SOHC VIN Z (1998)
DUAL REAR WHEEL, E-350
WHEEL HUBS AND BEARINGS
The rear hub is supported or floats on the axle spindle on two opposed tapered roller bearings. The rear hub is retained on the spindle by a ratcheting
nut that is tabbed to a slot on the spindle. The brake drum is mounted to the rear hub. A seal is installed inboard of the inner rear wheel bearing to keep
the rear axle and wheel bearing lubricant from the brake components. The full-floating rear axles on E-350 vehicles have brake drums mounted
outboard of the rear hub, permitting brake drum removal for brake inspection without the need to remove the rear hub. The E-Super Duty full-floating
axle has rear disc brakes. The rear disc brake rotor is mounted to the rear hub.
The rear wheel bearings are packed with a lithium-base grease, Premium Long-Life Grease XG-1-C or equivalent meeting Ford specification
ESA-M1C75-B, to provide initial lubrication until axle lubricant flows into the rear hubs and rear wheel bearing inner cone and rollers during vehicle
operation.
Vehicles equipped with Dual Rear Wheel (DRW) rear axles have the wheels attached to the brake drum on the E-350 vehicles or rear hub on E-Super
Duty vehicles.
