Service Bulletin

Description of Revisions: This service bulletin replaces the version
dated January 2001. This bulletin now refers to the appropriate
parts bulletin for parts, and contains updated warranty information.

General Information
Some vehicles may have been incorrectly shimmed at the factory, and may lean slightly to the right or left.
While this does not affect the operation of the vehicle, it may be visually unpleasing to many customers.
A vehicle is considered a "leaner" if one side is higher than the other by 3/8-inch (9.5 mm) or more when
measuring at the front axle from the ground to the lower frame rail flange.
To correct this condition, replace the existing front axle spacer on the low side of the vehicle with a thicker one
using the procedure below.

Procedure
IMPORTANT: This procedure is the only authorized alteration of the front axle spacer thickness. The
maximum allowable increase of spacer thickness is 1/2 inch (13 mm).
1. Park the vehicle on a level surface, apply the parking brakes, and shut down the engine.
2. Chock the tires.
3. At the front axle, measure the distance from the lower frame rail flange to the ground on both sides of the
vehicle.
4. If one side is higher than the other by 3/8-inch (9.5 mm) or more, check the height difference at the rear of
the frame rails. If this is significant, other adjustments will be necessary; otherwise, correct the height
difference in the front by replacing the low-side axle spacer with one of applicable thickness.
Refer to the applicable table in the parts bulletin for the correct thickness of the new front axle spacer.
For instructions on replacing the low-side axle spacer, refer to the applicable vehicle service/workshop
manual:
• Section 32.00 of the Heavy Duty Trucks Service Manual for FLB COEs and FLD Conventionals
• Section 32.00 of the Century Class Trucks Workshop Manual for Argosy COEs and Century S/T
Conventionals
• Section 32.00 of the Business Class Trucks Service Manual
• Section 32.00 of the Columbia Workshop Manual
• Section 32.01 of the Cargo Workshop Manual
• Section 32.00 of the Cascadia Workshop Manual
• Section 32.00 of the Business Class M2 Workshop Manual
• Section 32.00 of the 108SD and 114SD Workshop Manual

Warranty
This procedure is warrantable only if the described condition exists and the repair is performed within the
applicable base or extended coverage warranty period. If a failure is not found, this procedure is considered
preventive and warranty does not apply.
Normal warranty applies. See Table 1 for OWL VMRS codes and labor allowance information. Enter this service
bulletin number in the Service Bulletin # field.

NOTE: This service bulletin only applies during the initial operation period of the vehicle.
NOTE: This service bulletin is not applicable to vehicles with a body installed because the weight
distribution of the installed body may not be even, causing vehicle lean.
NOTE: This service bulletin is not applicable to gliders.
