Service bulletins for the 2013 Jeep Grand Cherokee

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.

90031992017-11-03. Service bulletin. STEERING; POWER TRAIN. Steering Column If vehicle comes in for steering column replacement, verify column installed. Go to Info Column in Star Parts and open the flow chart to determine which column is installed. If column is Daimler, verify that a replacement Daimler column is in stock and use for replacement. If no Daimler column is in stock, replacement must use Presta column (which require a number of other components to be replaced). For more information and details on PN's, see W-Series Flowchart in Star Parts. Contact parts specifying for assistance regarding correct part numbers, for technical assistance contact Star. UPDATE: 11/9/2016 If the new bearing does not fit through the double dash, you need to replace the lower double dash panel to the latest level. Please see the updated flowchart in StarParts for the correct replacement panel.
