2000 Expedition Rear Differential

[Erik Trevino]

Hey Guys,
I have a question

Its not a Explorer but its the bigger brother of the Explorer.
Its a family members car.
I have a question on the Rear Differential Fluid Maintenance.

When does it need to be changed? or Does it need to be Changed?
I thought the fluid didn't need to be changed unless you towed a boat and
the Diff. occasionally was submerged.
I just thought I would check here with you folks.
Any advice on Fluid Maintenance Recommendation is greatly appreciated!
I cant recall changing out the Fluid in my 95 Explorer, and at 150,000 Miles
its still rolling.

My Explorer (97) has synthetic fluid in the rear diff, and like you said, it
doesn't need to be replaced, ever, unless the axle is submerged.

Somebody else is going to ask you if I don't, so, what year is the
Expedition? It is possible that the earlier models didn't use synthetics
while the newer ones do.

Greetings,

Its a 2000 Ford Expedition.

I think the guys at the oil change place were just dicking around.
I was with my sister, its her expedition. They were talking to her. I just
humored them rolling my eyes in the passenger seat.
They Pulled out some plug with all this crud on it.
And basically gave the story that
"Your Cars Going to Explode the Minute you drive off the lot if you don't
let us do this $100.00 service"

If my 95 Explorer can make it 150K miles with out flushing the Diff, I
don't think there's any reason a Newer Suposively Better Built Vehicle cant
do the same.

I looked in the Maintenance Book and Fords website and cant find anywhere
about a Rear Diff Service at 30,000 Miles.

Ahhhhh, these shops.

So if there is suppose to be a service, let me know.
Or if there are any other thoughts to this matter

THANKS!!

Erik

All Expeditions come with 75w140 Synthetic Gear Oil in the Rear
Differential (but not in the front differential of 4WD vehicles - go
figure). The maintenance schedule that came with the vehicle said
something like -

"Rear axles and power take off (PTO) units containing synthetic
lubricant and light duty trucks equipped with Ford-design axles are
lubricated for life. These lubricants are not to be checked or changed
unless a leak is suspected, service is required or the axle assembly has
been submerged in water. The axle and PTO lubricant should be changed
anytime the axle and PTO have been submerged in water. Non-synthetic
rear axle lubricants should be replaced every 3,000 miles or 3 months,
whichever occurs first, during extended trailer tow operation above 21
Celsius (70 degrees Fahrenheit) ambient and wide open throttle for
extended periods above 45 mph. The 3,000 mile lube change interval may
be waived if the axle was filled with 75W140 synthetic gear lubricant
meeting Ford specification WSL-M2C192-A, part number F1TZ-19580-B or
equivalent. Add four ounces of additive friction modifier C8AZ-19B546-A
(EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear
axles. The axle lubricant should be changed anytime an axle has been
submerged in water."

Personally, I changed the lubricant in the front and rear axles of my
Expedition ever 50,000 miles. I also used synthetic lubricant in the
front differential of my 4x4 Expedition.

You should join the Expedition Owners Group and ask your question in
that venue. See http://g33ks.org/XOG/list.html .

Thanks for the discussion here. You saved me $80. The guys at the oil
change place tried to pull this one on me this morning. Showed me some
plug covered with gunk and small metal shavings. It's the second time
they've tried to get me to have the service performed. Luckily, I pulled
out my owner's manual, and told the guy I'd see what Ford recommends.
Hmmmmm, didn't see a thing in there about rear differential fluid. I told
him I'd do some research and have it done next time if I thought I needed
it.

Time for me to find a new place to have my oil changes done!

Thanks,

If they had pulled your drain plug ....what was holding your oil in?

What can happen to the rear bearings in a differential if you put in regular gear oil versus synthetic
