This bulletin applies to 2001-1012 Acura MDX, 2007-2012 RDX, 2005-1012 RL, 2009-2012 TL and 2010-2012 ZDX models. If the threads for the rear differential drain or filler plugs are stripped, there’s no need to replace the pricey rear differential case...simply repair the threads.
The Time Fastener Co. makes thread repair kits for these applications. Each kit includes a drill, a counterbore, a tap, tap guide and driver, along with five steel Time-Sert thread inserts.
To order these kits, call the Acura Tool and Equipment Program at 888-424-6857. Kit P/N TFC1815C is for 18 mm thread repair. P/N TFC2015A is for the 20 mm kit for RL models only.
