CAMPAIGN IDENTIFICATION NUMBER
Number 95S-0O1 has been assigned to this campaign. This number will appear on all communications and documentation of any nature dealing with the
campaign.
AFFECTED VEHICLES
SERVICE INFORMATION
Condition:
Certain 1994-95 Pickup models equipped with the 2.3L engine may experience gear oil leakage from the rear differential pinion oil seal. Continued
operation of the vehicle with a low gear oil level will result in damage to the rear axle assembly.
Possible Cause:
Analysis indicates that this condition is caused by deterioration of the pinion oil seal sealing surface, which could result in gear oil leakage.
Correction:
To correct this condition, dealers will install a new pinion oil seal and will replace the gear oil.
DEALER RESPONSIBILITY
Isuzu dealers are required to service all eligible vehicles at no charge to the owner, regardless of mileage, age of vehicle, or ownership.
Whenever a vehicle subject to this campaign is in a dealer's vehicle inventory, or arrives at a dealership for service, the dealer must take the necessary
steps to ensure that this campaign correction has been made before selling or releasing the vehicle.
Each Isuzu dealer will be supplied a copy of the AIMI Campaign Report (AWS-123-1A) listing affected vehicles assigned to that dealership. The report
contains VIN and detailed owner information obtained from state motor vehicle registration records. The use of such motor vehicle registration data for
any other purpose is a violation of law in several states. Accordingly, dealers are urged to limit the use of this listing to the follow-up necessary to
complete this campaign. If none of the affected vehicles are assigned to a dealership, no campaign report will be sent.
OWNER NOTIFICATION
American Isuzu Motors Inc. will notify, by letter, owners of affected vehicles already retailed (see enclosed copy). Dealers should send a Campaign
Reminder Notice (AIMI SVCF-1052) to all vehicle owners listed in AIMI Campaign Report AWS-123-1A. These postcards can be obtained from any
regional office.
