Service bulletin T-SB-0026-15

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

This noise can be addressed by replacing the needle bearing on the left side of the front differential. Refer to the Repair Procedure for Needle Bearing Roller replacement instructions.
