Add rugged protection to your rear differential with the Dorman - OE Solutions Differential Cover 697-734. This heavy replacement swaps out the vulnerable thin stamped-steel factory cover on the listed applications, including the 1997-2021 Ford F-150, 2003-2007 Ford E-150, 1997-2001 Ford Expedition, 1997-1999 Ford F-250, 2015-2020 Ford Transit, 2006-2008 Lincoln Mark LT, and 1998-2001 Lincoln Navigator — see the Buyer's Guide tab for the full list of Ford and Lincoln vehicles.

  • Enhanced protection: a rugged choice for off-road or snowplow trucks and SUVs that need extra defense from rocks, trail hazards, and debris that can ding an ordinary stamped-steel cover and lead to oil leaks and cracks.
  • Rigid construction: precision-engineered from thick ductile (also known as nodular) iron with an attractive, corrosion-resistant wrinkle finish.
  • Simplified maintenance: two filler plugs ease topping off compared with the factory plug on the axle housing, and a drain plug makes fluid exchanges quick while removing the need to replace the cover gasket.
  • Complete and customizable: comes with the required bolts and three plugs, plus a removable stainless steel Dorman logo plate you can swap for a plate and logo of your choice.

Engineered to the original equipment cover's fit and function for a seamless installation on the specified vehicles.
