Awright, you asked for it! Ha! Electricity and magnetism go hand in hand. Flowing electricity develops a magnetic field just like a permanent magnet has. The electric current flowing through motor windings creates a magnetic field. Oppositely, a changing magnetic field develops or induces a...

Yer a lifesaver!!

You can try putting in a heavier weight motor oil, if you can find single weight anymore. I'd try 40-weight. Hell, we used to put 90-weight gear oil in them in a pinch! If you go heavier, and find lower oil consumption, count on bad rings.

Well, ya don't want 60psi gasoline pressure leaking out under your hood! Worst comes to worst, see if a METAL tire valve stem cap fits those threads, and "glue" it on with good RTV Silicone rubber. Easily removable, should last pretty long. Check for leaks!

Chrysler's 727 was one of the bullet-proof early 3-speed automatics, and easy to service.

What you are seeing is CARBON build-up from excess oil consumption. How many miles to accumulate so much after you clean the? ALL the plugs? Valve stem seals only leak, mainly on intake valves. The exhaust valves are not exposed to the vacuum, sucking oil down the valves stems and burning it...

Here are a few 'scope pictures of alternator output voltage for several operating conditions: The variation is termed "ripple". These voltage waveforms are what the battery "sees". Note that if the battery is fully charged, it will have minimal effect on the ripple, which is inherent in load...

They LOOK identical to tire valves, but ARE NOT! Must resist gasoline. Have you tried Ford Parts? Early on in EFI, they had replacement parts for the systems, connectors, and such, and may have had the fuel Schraders. Don't think V-8 Schrader would be any different. Worst came to worst, get a...

Radio Frequency Interference filter, nothing more than a capacitor. Used to look like this: But only one wire?? How can a complete circuit be made?? A capacitor consists of an INSULATOR surrounded by two electrical conductors. See metal case screw hole? It screws down onto a grounded surface...

Very interesting thought. After shutdown, pressure in fuel rail and fuel line will "spurt" out a few ccs of fuel, then pretty much stop. Given combustion chamber volume of 40-50 cc, I don't imagine filling of the cylinder to cause lockup. Do not most EFI applications position the injector above...

Ok, OK! But simplifying technical concepts has often led to more confusion, at least for me. I've always felt the user of electrical components (Mechanic of vehicles) often lacks basic understanding of: necessity of a complete circuit, voltage as a FORCE causing electric current to flow, heating...

A "stuck" injector would load it's cylinder with lots of fuel, but nowhere near enough to cause hydrostatic lock, because the fuel evaporates very quickly in a hot cylinder. A leaking head gasket can cause a cylinder to fill with coolant, then cranking the engine can lock-up the crankshaft and...

I never expected this degree of misunderstanding and misquoting over something as simple as two batteries connected together, which is exactly what the alternator-battery combination is. The only difference is that the alternator is capable of providing a range of voltages, while a battery is...

Cause cannot be determined with certainty. Wiring the diff support bolts of the replacement will remove concern for loosening: (most bolts in aircraft applications are wired, I wonder why?).

Manual locking hubs do indeed "detach" the front wheels from the driving axles, no matter their type. Used for zillions of years successfully, but inconvenient for the Sunday drivers, so a variety of means of connecting/disconnecting, allowing slippage, etc., have been employed. Just as two...

Only rebuilding possible is replacement of bearings, brushes and diode bank. Voltage regulator not usually reworkable, but may be in some models. Generally, most common cause of failure is front bearing or brushes. Bad bearings make noise, squeal like hell, worn brushes can cause reduced output...

An important check, difficult but useful, might reveal the problem. The run-out present on the crankshaft end to which the flexplate fastens is critical; runout being measured on the Face of the runoutcrankshaft flange. Ford Shop Manuals call out a maximum allowable runout. I do not remember the...

Specific to the year, I cannot tell you much. However, the alternator in any vehicle is "told" to charge by the state of charge of the battery as well as the electrical load imposed while running. IOW, the battery has ONLY ONE main purpose: to start the engine. (Yes, in today's vehicles, it also...

Check U-joints first. Rear axle bearings and gears usually do not produce a rumble effect. However, a rear WHEEL bearing can sometimes.

If I recall correctly, they are 12mm 12-point bolts. Only a 3/8-inch drive socket will fit in there, a 1/2-inch will not clear the u-joints. Socket used MUST be 12-point. I had to use an impact to loosen them, very rusty, plus I believe Ford used a form of Loctite on the threads.

Pinion bearing noise ordinarily does not change in loudness with speed or throttle amount, but remains mostly constant. Noise which sounds like a whine and changes with speed and throttle amount, often going away when COASTING, is almost always GEAR NOISE resulting from bad differential support...

Not present in 8.8" design, only 9".

That's OK, if you know exactly which part(s) have failed, before seeing them all.

As @donalds points out, it does, as do most automotive differentials. One exception is the Ford 9-inch, which has THREE pinion bearings, two straddling the gear, giving added support. Here is a 9-inch pinion assembly showing the two tapered roller bearings, and the third straight roller...

In order of probable cause, 1- Battery cable connections. Must be clean and bright. 2- Solenoid on starter motor itself, replacement of whole assembly fixes it. Or, solenoid alone may be replaced. Have starter tested first, 3- Fender-mounted starter solenoid (relay) may be not making contact...

Driveshaft attaches to PINION FLANGE, far right. Pinion has two support bearings, visible. Axle shaft enters large bearing far left, one of two DIFFERENTIAL SUPPORT BEARINGS. Now, we are talking about the differential bearings. Yes, only outer races may be replaced, not desirable, however...

Confusing description, "rear differential input shaft bearing": input shaft implies PINION SHAFT, thus pinion bearing; the whole ball of wax is the "rear differential". I have always seen the bearing we are considering here referred to as "differential carrier bearing". Maybe I'm a nit-picker...

In the past I have purchased bearings individually as needed from a bearing supply house. Most OEM bearings are clearly marked with part numbers. Other parts like shims, crush washers, etc., are another problem, may be bought from a parts house.

Does the vehicle start? Or is this part of the PATS system? Does it chime constantly, or never? If chiming is the only problem, and it doesn't, you have a "chimed" life!

Axle Code D4 = Limited Slip, 3.73 gear ratio

My Ex is a 2004, purchased used in 2010. Had my share of problems, though nothing major: ABS Module died, TCC Solenoid failed, and Throttle Body failed (drive by wire). 170,000 miles, original shock absorbers, original fuel pump. Outstanding record, there. I will not buy a newer Explorer.

You started with an Explorer 2000 302 engine, do I understand correctly? Ford used several PATS schemes, the first being really stupid: If incorrect key inserted, PATS disabled the fuel injectors as I understand it, but still allowed the engine to crank. This meant the driver could suspect some...

A battleship might "feel" even safer!

Some claim PATS can be "programmed out" of the PCM. I have reservations, though. Secondly, it would help greatly to know whether the aftermarket theft system was in any way "tied in" with the PATS system. Or if clear understanding were had of just how the theft system worked, or was wired in, to...

Check for trouble code(s). Evaluation before that is pure guesswork.

You need to pay attention to the red security light reflected in the bottom edge of the windshield. Surely you've noticed it before? Under normal non-running conditions, it flashes on, then off, every 4 or 5 seconds. Inserting a key in the switch and turning to "ON" position, not start, if PATS...

Pinion bearings: FRONT, closest to driveshaft, REAR, farthest from driveshaft. Shims are used at the REAR location, between the bearing and the gear itself to locate the pinion properly for correct mesh with the ring gear. Shims are also used, usually a thick "crush washer" between the two...

If it stalls immediately upon putting in DRIVE, or any other gear, expect failed Torque Converter Clutch or it's apply controls, stalling engine in gear.
