- Component:
- Suspension:front:hub
- Manufactured:
- 01/31/1975 - 07/31/1976
- Affected:
- 12,602
- Notes:
- Front axle aluminum hubs.part no.33-m-2197.forging no readily identifiedon hub - 433-f-2138.possibility that a design deficiency exists in the forgedaluminum hub in the barrel between the inner and outer bearing which may resultin cracks and ultimately lead to failure of the hub.when a failure occurs,the hub is retained on axle spindle by wheel bearing adjusting adjusting.nut.continued operation after hub excessive brake lining heating which could causetire to blow could cause tire to blow or fire, with loss of vehicle control.(correct by replacing hub where necessary).
- Campaign:
- 76E003000 on 10/11/1979
- Component:
- Suspension:front:hub
- Affected:
- 28,000
- Notes:
- Possibility that a design deficiency exists in the forged aluminum hub in thearea of the wheel mounting flange which mayresulttest in cracks and couldultimately lead to hub failure.if a failure occurs, the flange along with thewheel and tire becomes disengaged from vehicle and rolls free in anuncontrolled manner.failure of the hub could also lead to a loss of vehiclecontrol without prior warning to the operator.(correct by aluminum hubs).
- Campaign:
- 78E002000 on 10/11/1979
- Component:
- Wheels:multi piece
- Affected:
- 2,200
- Defect:
- On the involved vehicles, casting deficiences exist in the area of the wheel mounting flange or the inner wheel bearing. when a flange failure occurs, the flange, along with the wheel and tire, become disengaged from the vehicle and may roll free. when a barrel section failure occurs, the hub is retained on the axle spindle by the wheel bearing adjusting nut. continued operation may then lead to hub failure, progressive damage to the hub, and eventually, separation of the hub, with the wheel and tire, from the vehicle.
- Correction:
- Dealer will inspect and replace all defective hubs with hubs of an improved design, without charge.
- Notes:
- Vehicle category: trucks.system: wheels; aluminum hub, part no. 333a911.consequences of defect: loss of a wheel assembly during vehicle operation couldresult in loss of vehicle control and an accident.
- Campaign:

- Correction:
- The dealer will replace the defective wheels.
- Notes:
- Vehicle category: passenger vehicles.system: suspension; cast aluminum wheels, part no. 30-5650.consequences of defect: should separation occur during vehicle operation, lossof vehicle control and an accident could occur.
- Campaign:
- 77E018000 on 10/11/1979
- Component:
- Wheels:multi piece
- Affected:
- 18,751
- Defect:
- The involved aluminum hubs may develop cracks in the barrel between the inner and outer bearing, which could lead to hub failure. upon failure, the separated hub is retained on the axle spindle by the wheel bearing adjusting nuts.
- Correction:
- Dealer will inspect and replace suspect front wheel hubs without charge to owner.
- Notes:
- Vehicle category: trucks.system: wheels; front wheel aluminum hubs, part no. 333p2304.consequences of defect: continued operation after hub failure could result in atire blow out or could allow the tire and wheel to separate from the vehicle.in either case, loss of vehicle control and an accident may occur.note: an audible sound along with thumping or wheel wobble may alert the driverto hub separation.
- Campaign:
- 76E009000 on 10/11/1979
- Component:
- Power train:axle assembly:banjo housing
- Affected:
- 1,491
- Notes:
- Rockwell l series axles are involved.possibility that axle housings may havea deficiency as a result of the friction weld location relative to the oil sealjournal radius.a deficiency in this location may cause cracks that couldultimately lead to failure of the spindle.if a failure occurs, the spindlewith its assembled parts consisting of a hub, drum, bearings, wheels and tiresbecome disengaged from vehicle and may roll free in an uncontrolled mannerwithout warning to the driver.(correct by inspecting and replacing with newhousing assemblies).
- Campaign:
- 77E027000 on 10/11/1979
- Component:
- Wheels:cap/cover/hub
- Affected:
- 20,586

- Correction:
- Dealer will inspect and replace suspect front axle hubs without charge.
- Notes:
- Vehicle category: heavy trucks.system: wheels; rockwell malleable hubs, part no. 333-v-1036.consequences of defect: hub failure could result in loss of vehicle control andan accident.note: vehicles should be inspected and any vehicle with a cracked hub flangeshould be removed from service until the hub is replaced.

- Notes:
- Vehicle category: trucks.system: wheels; malleable iron hubs, part nos. 333-q-2383, t-2438, and c-2551.consequences of defect: the hub will be retained on the axle spindle followingfailure, but continued vehicle operation will result in separation of the hub,wheel, and tire from the vehicle. this could cause loss of vehicle control andan accident.note: warnings of hub failure include wheel wobble, shimmy, or front wheelvibration.
- Campaign:
- 75E032000 on 10/11/1979
- Component:
- Service brakes, air:antilock
- Affected:
- 1,986
- Notes:
- Possibility axle assemblies equipped with wheel anti lock systems have beenassembled with an improper sensor to rotor gap caused by incorrectly adjustedwheel bearings and or improper positioned sensors, at low velocity, pulses maybe transmitted to anti lock computer which are falsely indicative of a wheellock up condition.if this should occur, by system design an air controlsolenoid will begin switching, and if this occurs during a braking application,reduction in retarding force may result on the affected axle and lengtheningthestopping distance with a sudden brake application at the end of the stop.(correct by inspecting and adjusting wheel bearing on all axles equipped withanti-lock systems).
- Campaign:
- 75E025000 on 10/11/1979
- Component:
- Service brakes, air:antilock:control unit/module
- Affected:

- Component:
- Steering:wheel and handle bar
- Manufactured:
- 04/30/1982 - 02/28/1983
- Affected:
- 18,672

- Notes:
- Vehicle category: heavy trucks; on/off highway specialty trucks.system: steering; front drive steering axle housings.desccription of defect: welds that join suspension components to the axle mayhave been improperly fused. in most cases, the defect will cause axle lubricantto leak in an area adjacent to the spring seat pads. under normal operatingconditions, the weld could crack without prior warning.consequences of defect: a cracking of the weld will cause the componentsattached to it (wheels, tires, brake drums, etc.) to roll free, causing a riskto traffic safety and possible vehicle crash and personal injury.note: detection of leaking axle lubricant should be followed by immediatelyremoving the vehicle from service. (this warning sign will not always appear.)
- Campaign:
