DON’T GET FOOLED

This bulletin applies to 2014-2017 Acura MDX and 2015-2017 TLX with SH-AWD. If you suspect a rear differential axle seal or pinion seal leak, the actual culprit may be something loose or damaged above this area.

A loose or damaged fluid pressure sensor will drip rear differential fluid onto the axle seal. A loose fluid pressure check port will drip fluid onto the pinion seal. Before considering rear differential replacement or service, be sure to check these two locations carefully to avoid unnecessary repairs.
