From: Bolte Brent
Subject: RE: FTE Small - Explorer Qs

The early model Explorers ( 1991-1995 ) had
two nagging problems that are somewhat costly to repair.
The first was with radius arm bushings. These
bushings, which mount the back of the radius arm to
the frame, were made of a rubber material an over a
short time would fail allowing the radius arm to move
fore and aft in the frame mounting hole. This would
normally only cause a clunking noise under the
Explorer during turns, but if bad enough could cause
handling and tire wear problems. The 1991-92 Explorers
were the worst with this and under warranty Ford would
normally replace them with an upgraded version that
didn't seem to wear as badly. The bushing on the
passenger side always failed more quickly because the
heat from the catalytic converter would soften the bushing
and make it fail quicker. I believe the upgraded bushing
was standard equipment on the 1993-94 models, but it is
something to look at none the less since having a dealer
replace them can run into hundreds of dollars quickly.
The second problem is the auto locking front
hubs on the 4X4 models. The problem with these hubs
stems from the fact that they use a plastic/nylon material
in the ratchet mechanism ( the part of the hub that keeps it
from exploding if somebody tries to engage the 4X4 system
under high slip/high torque conditions ( i.e.: front wheels
stopped, rear wheels spinning, and your foot still on the gas )).
The problem comes when the one of the plastic pieces in
the ratchet breaks, the hub ( or hubs ) will never lock under
any condition and therefore you will never have a functioning
4X4 system. I know several people that own 1991-94 Explorers
and some of them us their system year after year and have
never had a problem, others of them would have to have their
front hubs rebuilt every year at the start of winter ( and again,
not a cheap thing to have done ).
The best thing to do would be to have a mechanic you
trust look over the vehicle and have him check out the operation
of the 4X4 system ( if it is 4X4 ) and look over the other major
mechanical systems like engine/transmission and suspension
to make sure they don't see anything questionable. Despite all
of the problems you read about here ( which is the major reason
lists like this exist ) the Explorers have been a reliable vehicle
over the years. I'm on my 4th Explorer now and the two we
currently own ( a 95 and a 97 ) have never been to a service shop
for anything other than oil changes and tire rotations. One of the
other 2 had some minor problems, but they were all corrected under
warranty during the first year ( it was a 1991 model built in March
of 1990, a very early model ).
By the way, is it really the year 2000 where you live ??
Your post was dated Feb 14, 2000 ( Valentines Day ).

Hope this helps, Brent Bolte

hi jerry,
That's the Mass Air Flow sensor... It's mounted in the air duct between the
Air cleaner box and the throttle body. When you look at it, there is an
aluminum rib that runs top to bottom across the bore... On each side,
front and back, there is a hole. Spray the cleaner into the hole and it
will wash the gunk off the sensor elements of the unit. Be liberal and
spray the heck out of it, and make sure it's draining on to the ground and
not into the intake... Then re-assemble and go. Should take care of all
the ping. What happens is the elements get coated with grime, and actually
tell the computer that there is less air coming in than there really is...
the computer leans out the mixture accordingly, and you finally get to a
point where the mixture pings because it's too lean, and octane really
doesn't help. Cleaning it and it senses the proper amount of air and
starts running normal again.

If the MAF has been thoroughly cleaned, and it's still pinging, before
diving into engine/computer problems I'd replace the fuel filter... If it
get's clogged up, it will reduce the maount of flow to the injectors and
could cause a lean condition. If the ping doesn't seem to change with
extra octane from Premium fuel, then it's a lean problem... if it does
change, then it's most likely a timing/computer issue or a cooling problem.

Speaking with my father and brother, who own their own shop in California,
they have gone to the EEC training ford offerred for mechanics (pretty
expensive) and in that class, the Ford tech implicitly told them that if
the complaint on a ford MAF equipped vehicle was pinging and octane
increases didn't really help to pull the MAF and clean it. It won't damage
it unless you get poking at the sensor elements and break them.
He said 99.9% of the pinging problems on fords have been fixed with the MAF
cleaning. The other few cases have been ignition problems

Subject: FTE Small - Explorer Purchase

Hi Christopher J. Abele,

My advice about buying a 94 Explorer is....DON"T DO IT! I have a 93 4 door
XLT. We bought it new and had the following problems:

Upholstry sewn togather, Front end bushing squeek every 10k miles until 40k,
Front wheel bearings at 30k and 50k, Rust holes in the muffler at 45k,
Liftgate interior door panel vibrates at 2200rpm, Front U-joints at 50k, Rear
U-joints at 60k, Front end vibration started at 60k (second set of Firestone
ATX's put on at 80K and Ball joints at 100k) and at 105k it still vibrates at
60 mph. The drivers side door hinges have worn out, so the door sags when
opened. The arm rest is a weak design (ours has broke). The plastic panel
on the left side of the drivers side seat always catches my pant leg (it's
broke too).

Throughout our experience we are dissapointed with the Ford customer service.
We have to wait 1 week minimum for an appointment at the dealer. I had to
bring it back several times each for the Front End squeek and Wheel Bearings.
Recently the Dealer says "Oh yeh 91 to 94 explorers have problems with the
harmonics in the drive train and vibrate above 50 mph. We don't think we can
eliminate the problem but we can try to start replacing parts (at my cost)"
I stopped right there and am looking for a better solution via the internet.

You might ask why did you keep it for 6 years if you've had so many problems.
Good question. Replacement cost of a Chevy Suburban is streching our budget
and justification (D.I.N.K's). It's my wife's car and she likes the 4x4,
size and doesn't mind the maintainance problems (because I deal with it).

No other Blue Oval will ever be parked in our garage! If anyone has ideas
about the front end vibration, they're welcome.

Subject: RE: FTE Small - Explorer Qs

Sorry, when I was referring to the "Early model
Explorers" I really meant 1991-1994. In 1995 when
the Explorers went through their first somewhat
major redesign, Ford did away with the twin I-beam
front suspension and the old touch-drive 4X4 system
in favor of the short/long arm front suspension and
the Control-Trac 4X4 system. This eliminated the
two problems I mentioned because short/long arm
front suspension no longer had radius arms ( so no
radius arm bushings to wear out ) and the Control-
Trac 4X4 system no longer used the mechanical
auto-locking front hubs ( the 1995-96 Control-Trac
systems had a vacuum operated axle disconnect in
the front differential and the 1997-present Control-
Trac systems leave the front drivelines connected
and turning at all times ). Sorry for mix up in the
years for the "early Explorers"

Thanks, Brent Bolte

Subject: Re: FTE Small - Ford Ranger Auto Transmission

Having 4 Ford dealers within 30 miles doesn't guarantee that you will be
treated fairly. Here in the Phoenix area I can think of at least 6. The two
that I have been to (Berge & Earnhardt) both take the attitude of
reluctantly fixing it until the warranty runs out, then you are on your own.
Both of them have told me countless times that "they all do that", "we can't
find the problem, so we can't fix it", and "yes, we can replace the broken
part with the same one that we know will fail again, however, once your
warranty runs out you will have to pay to have it replaced with the same
inferior product". As an example, the seat tilt bracket on my '97 Explorer
bends down when I get out. There are many reports of this problem from
others. It broke off in February of '98. My Ford dealer replaced it under
warranty. It broke off again in December of '98. A different dealer once
again replaced it under warranty. I had 31,000 miles on it then. Now the
bracket is bent down for a third time. If I try to straighten it out, it
will break off. The problem is I have 42,900 miles now. Berge's response is
a) I am out of the manufacturer's warranty and b) the warranty on the one
replaced in December was 12 months/12000 miles. There was a TSB issued a
couple of months ago regarding the breaking brackets. Ford has redesigned
them to include a small ridge that significantly strengthens the bracket to
prevent further breakage. Berge says "sorry if I want the new brackets, I
have to pay for them". I can't wait to see my repair bill when I go to pick
it up this afternoon. I told them to skip the brackets. On my ticket, they
wrote down $35 evaluation fee for LH bracket and $35 evaluation for RH
bracket. I asked the service writer "does this mean you will charge me $70
to look at my brackets and say "yup, they're bent"". He said he had to put
an evaluation price down in case I don't have them repair it. I will try
going back to Earnhardt's to see if they will pay for the brackets since
they replaced them in December. I hate doing that since I had to take my
Explorer back to them 6 times since the repair in December to have things
fixed that they messed up.

Subject: FTE Small - Tire wear

I seem to be having a recurring problem with front tire cupping / feathering
on all 3 Ford Rangers I've owned and my current '98 Explorer.
On the Explorer, we've had the front end aligned, new shocks, bushings
replaced, and new Michelin radials all around, and we STILL have the
feathering.
We don't drive off road, hit pot holes, or corner hard and tow light loads
occasionally. The Michelins only required the tiniest of weights
(every time) to balance. Also, the dealer told me that there is no "4 wheel"
alignment for these, Is this true?
I 'm really disappointed, since I thought that the new front suspension
design would have solved this.
Is this a "Ford truck" thing? Will I have to realign the front end every
20,000 miles and / or rotate & rebalance the tires every 5,000 miles?
Or is there a non-stock alignment spec or after market suspension parts that
would help solve this?
ANY ideas would be appreciated.
Love the reliability, hate chewing up expensive tires!

Rob,

I have seen the feathering on my '96 Explorer. I thought it was a
combination of my driving habits, and not rotating the tires enough. I do
it about every 10K miles, but started doing it around 7K miles since the new
set of Wrangler Radials were installed. I've heard mixed emotions on these
tires, but I got almost 60K out of the first set. OK by me.

First of all Rob, you should be rotating your tires every 6,000 miles
anyway. This solves alot of tire wear issues. Tires will go out of
balance no matter what kind of car you drive. Just some cars it is more
noticeable then others. This is just part of the maintenance associated
with owning a vehicle. My wife has a 92 Escort and her tires can go
way out of balance and not affect ride quality at all. I have a 97 Ranger
4x4 and rotate the tires every other oil change (6,000 miles) and have
no problem with unusual tire where.

Subject: FTE Small - Re: Cleaning MAF

Hey all,
I had a problem with my check engine light coming on a few months ago and
when I went to my mechanic he ran the codes in his computer and he said he
didn't know what to do and to take it to the dealer... I took it to the Ford
Dealership and they told me I needed a new MAF...

That began a long drawn out process of research... After researching it I
asked a few people on the web about the whole thing and they told me just to
clean it... Well that was 3000 miles ago and I haven't seen the light
since... and my MAF seems to be functioning fine... Also I notice a gain in
power and better performance... Pre cleaning I noticed that when I pressed
the accelarator in a higher gear, the RPMs would jump irregularly. That
only happened every so often and when I cleaned my MAF it seemed to
disappear. That's my experince with them. If you have any questions about
them, go to... http://www.ford-trucks.com//lc/lc.php?action=do&link=http://www.4x4 central. com /tips.htm#mas... great site... It
has lots of excellent info on Explorers and Rangers. I have a 94 Explorer.
Note, if you do decide to go ahead and do the cleaning instead of purchasing
a new MAF, you will need to clean the sensor itself... I tried only cleaning
the screen part of the MAF that didn't help at all. In order to accomplish
this you may need to purchase a set of security star bits. I found them at
NAPA auto parts. You'll probably need to go to a parts store for them.
Also when I was doing my research i found out that the aftermarket MAF's
don't replace the sensor they only replace the screen part of it. I don't
know that may only be the two companies I looked into. I hope that helps
ya. Good luck!! If you fourwheel and need a place to go on the east coast
let me know... :) I've got a great one that's legal!! :)

Happy Wheelin,

would see a cloud rush by the truck before I started moving. Now it seems
as though I start the car and it seems like constant white smoke for awhile.
I'm going to try the hot start thing, and see what happens. This is not
ALWAYS the case, I have started it and there has been no white smoke.

I will check this tomorrow.. I noticed that my coolant does look like
"coffee with cream" as Bob suggested. I lent this to my cooling system
needing a flush (something I plan to do this weekend).

> Unexplained coolant loss with positively no leaks found.

No leaks.

I apriciate the reply.. your suggestions lead me to another question: what
causes a blown head gasket?!
