- Affected:
- 4,495
- Defect:
- Vehicle description: heavy duty trucks built with rear leaf spring suspensions (models 4700 built with rear leaf suspensions and manufactured from december 9, through december 16, 1998; models 3400 and 3800 built with 14sbk rear leaf spring suspensions and built april 14 through may 10, 1999; and models 3400 and 3800 built with rear leaf spring suspensions and manufactured from may 10 through may 18, 1999). on vehicles where the frame to axle hose length was too long, a chafing condition exists on suspension components, which could result in hose rupture. on vehicles where the hoses are too short, a hose separation could occur with severe suspension articulation.
- Consequence:
- If a hose ruptures, the rear brakes will fail increasing the risk of a vehicle crash.
- Correction:
- Short hoses will be replaced and the long hoses will have a hose routing kit installed to prevent any chafing problems.

- Affected:
- 944
- Defect:
- Vehicle description: heavy duty trucks. there is interference between the air brake s-cam and the end of one of the knuckle studs. as the brake shoe lining wears, the s-cam rotation may be limited by the interfering knuckle stud. if the s-cam can not rotate through its full range of motion, the braking force can not be fully transmitted from the brake shoe linings to the brake drums.
- Consequence:
- This could result in a longer stopping distance or a dragging brake condition.
- Correction:
- Dealers will shorten the interfering knuckle stud to eliminate the clearance problem.
