- Component:
- Suspension:rear:springs:leaf spring assembly:u-bolt, leaf spring to axle
- Affected:
- 900
- Notes:
- Used on lightweight recreational trailers.possibility that trailers equippedwith kelsey-hayes axles may experience loosen u-bolt assemblies which fastenthe suspension (spring assembly) to the axles.if this condition conditionexists, the axle may loosen, leading to the loss of control of trailer andpossibility of a vehicle crash without warning.(correct by inspecting andtightening u-bolt to specified foot pounds of torque).
- Campaign:
- 78E010000 on 10/11/1979
- Component:
- Service brakes, air:antilock:wheel speed sensor
- Affected:
- 2,400
- Defect:
- The involved anti-lock hardware sensor portion may be defective. loss of anti-lock capability and reversion to normal braking could occur.
- Correction:
- If the anti-lock system fails, a warning light should alert the driver to the problem. corrective action: dealer will inspect and replace all defective sensors, without charge.

- Component:
- Wheels
- Affected:
- 3,179
- Notes:
- Size 15 x 6 lbh wheels shipped to dexter axle company.possibility wheels hadmetallurgical defects in steel used for fabrication.if this condition exists,it will contribute to shorter fatigue life when the material is under tension.wheel falure could result in loss of vehicle control and possible crash.(correct by inspecting and replacing with new improved wheel).
- Campaign:
- 76E013000 on 10/11/1979
- Component:
- Service brakes, hydraulic:foundation components:drum:drum
- Affected:
- 748
- Notes:
- Gunite part no g-2705, size 16.5 x 7, for use on rockwell rn axles equippedwith disc brakes.possibility that the brake drum may be undersized in an areaon the back face just below the mounting surface.if this condition exists,the thick- ness of the drum in this area is below specification, and thestructual strength of the drum is adversely affected and failure could result.(correct by inspecting and replacing brake drums where necessary).
- Campaign:
- 79E009000 on 10/11/1979
- Component:
- Suspension:rear:axle:non-powered axle assembly
- Affected:
- 1,500
- Defect:
- The weld between the spindle and axle beam is not uniform. as a result, the insufficient weld could cause separation of the spindle from the axle beam.
- Correction:
- Dealer will replace the defective axle beam assembly at no cost to owner.
- Notes:
- Vehicle category: trailers.system: suspension; axle.consequences of defect: a wheel could separate from the vehicle and result inloss of vehicle control and an accident.
- Campaign:
- 77E009000 on 10/11/1979
- Component:
- Suspension:rear:axle:non-powered axle assembly
- Affected:
- 2,600
- Defect:
- The involved axles may have been welded with cold forged spindles that may fracture during vehicle operation.
- Correction:
- Dealer will replace all involved axles.
- Notes:
- Vehicle category: trailers.system: equipment; 10k cold forged rear axles.consequences of defect: if spindles fail in service, loss of vehicle controland an accident could result.
- Campaign:
- 74E035000 on 10/11/1979
- Component:
- Service brakes, electric
- Affected:
- 40,000
- Notes:
- Possibility that a loose coil with- in the magnet assembly, of the electricbrake, may lead to a short circuit.if this occurs, braking action of anaffected brake will be lost and a crash could result with- out prior warning.(correct by inspecting and replacing with new magnets where necessary).
- Campaign:
- 75E031000 on 10/11/1979
- Component:
- Service brakes, air:antilock:control unit/module
- Affected:
- 2,100
- Notes:
- Possibility that the computer modules are adversely affected by certain radiofrequencies at power levels in excess of 30 watts when in close proximity tothe computer modules (such as on-board radio transmission).if thiscondition exists, malfunctions that can occur include loss of brakes on one ormore axles.continuous radio frequency interference for more than fourseconds, the seconds, the anti-lock warning signal will be engaged and brakeswill be fully operative without anti-lock capability.(correct by inspectingand elimating radio interference).
- Campaign:
- 75E020000 on 10/11/1979
- Component:
- Service brakes, hydraulic:foundation components:disc
- Affected:
- 363
- Notes:
- For use in small recreational trailors.possibility that either or bothcracked hubs and/or a hydraulic leak may develop in the disc brake assemblies.if the hub is cracked, it may result in movement of the brake assembly suchthat it can become jammed against the wheel or other components.if hydraulicleakage occurs, hydraulic pressure may be lost resulting in the loss of brakingcapability.(correct by inspecting and replacing with improved disc brakeassembly).
- Campaign:
- 80E013000 on 07/29/1980
- Component:
- Wheels
- Manufactured:
- 10/31/1978 - 10/31/1978
- Affected:
- 56
- Defect:
- Certain vehicles may have been equipped with the wrong size wheels. these wheels have a lower load carrying capacity which could lead to trailer overloading, rim material separation in the bead seat area, loss of air and possible separation of tire and rim from the trailer.
- Correction:
- Owners should inspect their wheels, including the spare, for a marking of "15 x 5". these will be replaced by "15 x 6" wheels without charge to owners.
- Notes:
- Vehicle category: travel trailers.system: suspension; wheels; hayes, model nos. 3000 and 5000 series 33 and 55.consequences of defect: damage to or loss of wheel rim and tire could result inloss of vehicle control and an accident.
- Campaign:
- 84E002000 on 02/27/1984
- Component:
- Service brakes, electric
- Manufactured:
- 12/31/1982 - 11/30/1983
- Affected:
- 113
- Defect:
- Open electrical circuit in wire supplying current which activates the electric brakes is caused by fatigue of lead wire.
- Correction:
- Repair kits will be available to upgrade vehicles in the field. repair work will be handled by local dealers or kelsey axle and brake field service representatives. repair work will consist of a new magnet (and attached lead in wires) and magnet arm assembly.
- Notes:
- Vehicle category: fifth wheel commercial trailers equipped with axles having agross weight rating of 4,500 lbs.system: brakes, electric.consequences of defect: the effect of this open circuit is a progressivereduction in the braking capability of the trailer. if failure occurs, thehydraulic brake system of the tow vehicle will remain intact and is capable ofproviding substantial braking of the combination vehicle.poor brakeperformance, which is more likely to occur in vehicles in severe commercialservice, could result in loss of vehicle control and an accident.
- Campaign:
- 87E031000 on 08/18/1987
