2009 Ford Mustang Differential Cover Parts Q&A

• Q: How to service the differential cover on a 7.5-inch ring gear rear drive axle on 2009 Ford Mustang?

  A: The servicing process for differential covers of Ford 7.5-inch ring gear rear drive axles requires the vehicle to be placed in neutral gear and elevated on a hoist. Start by removing both the 10 housing cover bolts and emptying the lubricating fluid from the housing followed by removing the cover. Clean both differential housing surfaces as well as the cover surfaces before installation because oil must be totally removed from these areas while keeping the axle interior sealed against potential contamination. The specified silicone sealant should be applied along the differential housing cover in an unbroken strand with appropriate thickness then installed within 15 minutes so a reapplication of sealant is not necessary. Secure the differential housing cover by using 10 bolts which need torquing at 46 Nm (33 lb-ft). The refilling process starts with placing the vehicle at ride height on a level surface and then removing the filler plug followed by adding 1.42L (3.0 pt) of specified lubricant until it reaches 11.1-12.7 mm (0.44-0.50 in) below the fill hole bottom edge. Finally, reinstall and tighten the filler plug to 30 Nm (22 lb-ft).
