Dealer Service Instructions for:
Customer Satisfaction Notification E05
Oil Pump Drive Gear
A revised drive gear parts package has been released. The second roll pin hole must be drilled in the revised drive gear.
2005 (TJ) Jeep(R) Wrangler
NOTE : This notification applies only to the above vehicles equipped with a 4.0L eligible ("S" in the 8th VIN position) and an engine build code between 902944 (October 20, 2004) and 900325 (February 1, 2005).
IMPORTANT : Some of the involved vehicles may be in dealer vehicle inventory. Dealers should complete this repair on these vehicles before retail delivery. Dealers should also perform this repair on vehicles in for service. Involved vehicles can be determined by using the VIP inquiry process.
The oil pump drive gear on about 16,000 of the above vehicles may wear out prematurely and cause engine failure due to a loss of oil pressure.
The camshaft position sensor/oil pump drive assembly date code label must be inspected. Units within a specific date code range must have the drive gear replaced.
All unsold vehicles must have the oil pump drive gear replaced prior to retail delivery to eliminate the risk of engine failure due to premature oil pump drive gear wear. On sold vehicles, the cam/crank angle must also be checked with the DRB III scan tool. Engines found with excessive cam/crank angle must have the oil pump drive gear and the engine camshaft replaced.
Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if inspection determines that an engine camshaft is required and the vehicle must be held overnight.
The Special Tools may be required to perform this service procedure.
Completion Reporting and Reimbursement
Claims for vehicles that have been serviced must be submitted on the DealerCONNECT Claim Entry Screen located on the Service tab. Claims submitted will be used by DaimlerChrysler to record Customer Satisfaction Notification service completions and provide dealer payments.
Use one of the labor operation numbers and time allowances shown.
Add the cost of the parts package plus applicable dealer allowance to your claim.
NOTE : See the Warranty Administration Manual, Recall Claim Processing Section, for complete claim processing instructions.
All dealers will receive a copy of this dealer notification letter by mail. Two additional copies will be sent through the DCMMS. This notification can be viewed on DealerCONNECT by selecting "Global Recall System" on the Service tab, then clicking on the description of this notification.
Owner Notification and Service Scheduling
All involved vehicle owners known to DaimlerChrysler are being notified of the service requirement by mail. They are requested to schedule appointments for this service with their dealers. A generic copy of the owner letter is included.
Enclosed with each owner letter is an Owner Notification postcard to allow owners to update our records if applicable.
Vehicle lists, Global Recall System, VIP and Dealer Follow UP
All involved vehicles have been entered into the DealerCONNECT Global Recall System (GRS) and Vehicle Information Plus (VIP) for dealer inquiry as needed.
GRS provides involved dealers with an updated VIN list of their incomplete vehicles. The owner's name, address and phone number are listed if known. Completed vehicles are removed from GRS within several days of repair claim submission.
To use this system, click on the "Service" tab and then click on "Global Recall System." Your dealer's VIN list for each recall displayed can be sorted by: those vehicles that were unsold at recall launch, those with a phone number, city, zip code, or VIN sequence.
Dealers should perform this repair on all unsold vehicles before retail delivery.
Dealers should also use the VIN list to follow up with all owners to schedule appointments for this repair.
VIN lists may contain confidential, restricted owner name and address information that was obtained from the Department of Motor Vehicles of various states. Use of this information is permitted for this notification only and is strictly prohibited from all other use.
If you have any questions or need assistance in completing this action, please contact your Service and Parts District Manager.
