PML Ford F250 Differential Covers Install,
American Functional Art
I f 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.

| Putty knife my
foot, instead of bending several putty knifes, we used a pry bar
to remove the old cover. |
Lok wheel and air
gun get the old gasket off fast. Just be careful to get it all
out of the exposed differential. |
Brake parts cleaner
speeds up cleaning the gasket surface, but again clean it all
out of the open diff. |
Nice hardware comes
with the PML covers. Hex bolts with washers, magnetic drain plug
and a fill plug. |
Drain plug, fill
plug.

parts cleaner and for a quick gasket, it's hard to beat Permatex
"Right Stuff" |
Using the "Right
Stuff" squeezes out like party cheese, as per PML instructions,
we stayed on the inside of the bolt holes. |
Going back together
is easy, smiling as you improve the looks of your truck. The PML
instructions give you the torque ratings for the bolts.
Tightening in a star pattern just like your wheels. |
I like Amsoil, used
the factory viscosity weight 75w-140 for the rear and since it
will be synthetic now, I went a little heavier with 75w-110 for
the front differential. |
Most folks will use
a pump for adding gear oil, but we had room and the fill hole
was easy to access, so a funnel worked just fine. |

 |
| PML, made in
America just like me. I love it when I find great truck
accessories that didn't have a long boat ride from a communist
country. |
The front
differential was a little harder to get to the cover with all
the steering rods and tracking bar. |
Front pans, old and
new. With the price of trucks, we are keeping trucks longer.
These are the types of accessories that will get you those extra
trouble free miles. |
Room for the extra
oil capacity and the cooling fins. It just looks cool.
 |
Again, enough room
to just pour the oil in with a tube on the oil bottle. |
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.
