PML Ford F250 Differential Covers Install, American Functional Art

If you've read your trucks owner manual, there is a different schedule for normal use and "severe or trailer towing". For some maintenance schedules you change oil twice as often for severe use. Towing stress creates heat, heat breaks down the oil faster and you know what happens next. A lot of us overload our trailers especially using 3/4 and one ton pickups. My 2006 Ford F250 came with synthetic gear oil in the rear differential  but regular gear oil in the front diff. When you open your factory diff cover, if you haven't changed oil for the first time, you'll find metal filings. No factory drain plug, no factory magnet to catch the metal filings. One of those manufacture things where they don't care about or figure you won't know about. That's why the accessory world flourishes, to finish the job of building your truck right.

PML does it right, with heavy duty cast aluminum 3/16 inch thick with 3/8's inch flange. Compared to a stamped piece of tin. See the picture, left, PML covers have exterior fins and a couple pints extra oil capacity for cooling your hard working oil, and look at the size difference. A fill plug and a magnetic drain plug, make future maintenance easy with PML. Made in the USA and what else would you want?

The ugly factory beast, no drain hole, low oil capacity, can you suck all the gunk out at service time? Right picture, a beautiful rear, cover with cooling fins, more oil, less heat, magnetic drain and a fill plug.

Hardest part of the install is prying the old pans off. Our truck had 40k miles and the factory gasket was doing it's job. Leaving the top bolt in, the pry bar opened the pan and let the oil drain. We used a Lok wheel on a air gun to take the factory gasket off the differential face. Brakes parts cleaner finishes the job, cleans the surface of the gasket surface on diff and cover and dries fast.

Look at your owners manual for fluid capacity. The rear will be increased by a quart and the front by a little over half a quart. The front diff cover has the fill plug on the side so when it's full it will run out. The rear diff cover measuring the oil going in is more important.
