Show/hide table

Certain 544-4188 Sun Gears were incorrectly manufactured. Earlier hour failure of the sun gear and resulting damage to the axle final drive planetary gears and ring gear can result.

ACTION REQUIRED

Show/hide table

Inspect all 544-4188 Sun Gear in dealer part stock. Inspect the gear for suspect heat code M071589.

- If the heat code matches M071589, the part is bad, remove the part from dealer parts stock.

- If the heat code is NOT M071589, all other heat code parts are good. Mark the packaging as inspected per this program and return the part back to dealer parts stock.

This part number is a new part number beginning in November 2019.

If your Dealerships Service Dept has used any of these defective parts please create a Global Dealer Solution Network (GDSN) Product Health Service Request (SR) with the priority of "Product Inquiry / Informational" and a Workgroup / Subsystem as "Drive Train". Add any pertinent photos and detailed failure information for the product group. Mention the CPI number #477189 in the CPI field. Also, please populate the part number in the part number field prior to closing the SR at the Dealership without submitting to AVSpare. This will alert the CPI Team that you have documented this failure in Product Support Customer Relationship Management (PSCRM).
