- Affected:
- 9,000
- Defect:
- The involved vehicles fail to comply with federal motor vehicle safety standard no. 204, "steering control rearward displacement". the aluminum front spring rear bracket is subject to breakage. this bracket, along with the taper leaf front springs, attaches the spring shackle to the chassis frame.

- Engine and engine cooling:engine
- Manufactured:
- 03/31/1978 - 06/30/1981
- Affected:
- 15,000
- Defect:
- Due to a deficiency in material strength, the front engine support brackets on the involved vehicles may develop cracks that could lead to bracket failure. this would cause the engine to drop down into the radiator, damaging the shroud, engine fan, and other associated parts. the engine throttle could be pulled into full governed position.
- Correction:
- The existing support brackets will be replaced with brackets made of ductile iron, at no charge to owner.
- Notes:
- Vehicle description: trucks.system: structure; front engine support brackets.consequences of defect: with the throttle locked in this position, the driverwould have no control over vehicle speed. loss of vehicle control and anaccident could follow.
- Campaign:
- 81V094000 on 08/10/1981
- Component:
- Suspension:rear:springs
- Manufactured:
- 04/30/1978 - 08/31/1981
- Affected:
- 1,000
- Defect:
- Inadequate weld positioning coupled with radius rod load and loosening of the spring clip nuts could cause spring seat fracture. this can result in loss of directional control of the axle.
- Correction:
- Spring seat radius rod brackets will be inspected and replaced if necessary. in addition, supplemental brackets will be installed to reinforce the spring seat, without charge.
- Notes:
- Vehicle description: heavy trucks equipped with rockwell internationalsqhd-sqhp rear axle and dayton truckmaster suspension.system: suspension; spring seat/radius rod bracket.consequences of defect: this defect could cause a loss of vehicle controlwithout prior warning and may result in an accident.
- Campaign:
- 81V156000 on 01/07/1982
- Component:
- Vehicle speed control:springs
- Manufactured:
- 10/31/1978 - 07/31/1981
- Affected:
- 186
- Defect:
- The throttle return springs on the affected vehicles provide less than the required torque, causing a sluggish return of the throttle to the idle position after the accelerator pedal is released. this fails to comply with the requirements of federal motor vehicle safety standard no. 124, "accelerator control systems".
- Correction:
- New anchor brackets and spring extensions for the throttle return springs, will be installed at corrected locations without charge to owner.
- Notes:
- Vehicle description: trucks.system: fuel; throttle return springs.consequences of defect: a failure of the accelerator function to respondnormally could cause an accident in certain traffic situations.
- Campaign:
- 84V036000 on 04/10/1984
- Component:
- Suspension:rear:springs:leaf spring assembly
- Manufactured:
- 09/30/1978 - 04/30/1982
- Affected:
- 3,421
- Defect:
- Spring seat can deform, which causes a decrease in the clamping force in the suspension assembly. loss of clamping force may bring about axle misalignment or axle housing failure.
- Correction:
- The axle housing will be inspected and replaced, if necessary. the spring seats will also be replaced.
- Notes:
- Vehicle description: heavy trucks.system: suspension; rear spring seat.consequences of defect: loss of vehicle control could occur without warning,possibly resulting in an accident.
