For above: 1) follow advice of @CDW6212R for header info. I'm "way earlier" in that respect. 2) Beware that certain functions you do not need are tied into the PCM for safety considerations. If you expect to utilize full EFI operation, and wind up with ABS requirement, that function is capable...

Upon lock-up, assuming normal conditions, the TCC (Torque Converter Clutch) engages, or locks, very gently, sometimes unknown to the occupants of the vehicle. Upon throttle demand, like starting to climb a hill or acceleration called for, the TCC disengages, or unlocks, with a surge felt in the...

Great idea! Can't tell, EFI? See no manifold yet. Looks like a small block V-8. Please ask more detailed questions; "tips" might not apply.

The Ford 9-inch differential, for example, had NO CROSS PIN BOLT, or any other kind of retainer. The exposed ends of the cross bolt were COVERED by the installed ring gear; thus the cross bolt could go nowhere. The pic below shows how it looked: It's a beautifully-designed set up. It had a...

Who here has installed one with NO THREAD LOCKER and had it come out during use? Years back, the hundreds of ring gears I mounted were attached with lubricated grade 8 bolts, only oil on the threads. Never had one back out. The really crazies designed them with wire holes, wired the bolt heads...

Here's a trick I learned after MANY bead headaches. If new tire being installed, always be certain it was STORED vertically, not with a ton of tires lying flat on it. Check distance between beads; if close together, you will likely have trouble seating. A lot has to do with the rim, also, if...

Ha!! Good one! He only wants to isolate noise source. If it IS in the differential or ring and pinion, then he will proceed as you say.....

Yes, axle removed leaves a gaping hole. Since the guts are stationary, no rotation, a cork or other soft plug entered into the two holes would prevent sloshing out, and dirt entering. The driveshaft input is of course sealed by a yoke. The holes, btw, have no shaft protruding since the axles are...

Late '50s, I took a drastic chance by trying ATF in my 3-speed overdrive transmission. Recommended was GEAR OIL. Shifted smoother, worked well. I questioned the much-touted claim that gear lube had ability to withstand higher pressures than m ost other lubricants. Pressure depends on area of...

The seal engineers would tell you the "cleaning agents" contained in the synthetic loosened deposits on/around the seal lip which were preventing leakage (assuming it was a seal, and not a gasket). This I've always doubted, but WTH, sometimes magic is involved.

Are you at all familiar with just exactly what makes "diesel" rating qualify? I've heard additives not used in common motor oils. Then there's the rating "system", which once was straightforward and made sense, now consists of gibberish of letters and numbers.

Most fill plugs (not all) have square male heads; some have square or even hexagonal female sockets. I have seen them sized from 1/2-inch standard pipe thread size to 3/4-inch. But tell me now, given the fact that pipe threads are TAPERED to promote sealing, how would you tell one in Standard...

To really find out, run it with no front axles in place and front driveshaft removed. If noise persists, look elsewhere than front differential.

I have been using Shell Rotella T-3 15W-40, non-synthetic in my '04 Explorer for about 60,000 miles now, have 170,000, uses none between changes (4000 miles = 1/2 qt). This is a diesel-rated lubricant for which I had to convince some here that it would not "wreck" my engine, 4.0L SOHC, original...

One can also hold the pump pulley with a giant pipe wrench......

Reason for doing this? How does 1/2 normal schedule change anything from full schedule?

I have a story. Ordered 65 Mustang brand new, Aug, 1964. 5 weeks delivery, ordered High Performance Package, 289-271 HP, solid lifters, forged pistons, up-graded rings. Ran with Texaco Havoline 10W-30 for quite a long time, then Mobil 1 Synthetic came out, so I tried it. Car had crossed entire...

I think the Ranger would have an 8.8 Ford solid axle rear end. The Expedition in '97 had as an option an air bag suspension, otherwise I believe coil springs. This would contrast with the Ranger's leaf springs, making swapping difficult. Additionally, the Expedition may have used the Dana Model...

Do you have any maintenance history on it previous? Perhaps transmission fluid replace? It wouldn't hurt to install a high quality cooler up front. More evidence of condition will be revealed when you remove the pan. Check fluid quality, look for debris. If the transmission seems to function...

"The ring pinion is always rotating. Thats why I believe its not the input shaft bearing on rear differential" The "pinion" gear is turned by the driveshaft. The "ring" gear is solidly attached to the differential carrier, supported by two tapered roller bearings. The pinion turns when the...

In doing so, the vehicle may not move at all in 4X4 AUTO, and will need to be switched to 4X4 HIGH to activate the front driveline.

But only because every mistake that can be made, I DID, and kept careful mental track avoiding repeats. First, whine or howl under load (55 mph, working to keep vehicle rolling) which disappears upon release of gas pedal and returns upon depressing it, almost always originates in GEARS...

Either is good, so long as it does not LEAK. Dana Corp. was applying Silicone Rubber to seal their differential covers using no convential gasket way back in 1978 when I visited their Spicer Plant in ft. Wayne, Indiana. Computer controlled application of goop.

There is a RAFT of misunderstanding going on in this thread, IMO. The Double Cardan Constant Velocity Joint shown (one is calling it "DC", not all will recognize that) is a specialized U-Joint coupling which provides constant velocity to both input and output shafts, by using two standard...

OK, I was misleading myself, talking about CV JOINTS usually implies axle shafts, NOT DRIVESHAFTS. The FRONT DRIVESHAFTS have used a unique CV joint up by the transfer case only, none (only U=joints) on rear driveshafts.

There are NO CV joints in the rear drivetrain in 1999. It has a solid rear axle.

Happened only when water was involved? Check ignition coil and it's connections for excessive dirt: moisture absorbed can short out the high voltage to the plugs, resulting in no start. Dries out, starts.

Yes, a good idea. While such hoses are exposed to very low pressure, aging hardens them, and should one crack while on a trip, you could be stranded.

This is news to me, thank you! I exist in the dark ages of automotive lore!

The amount of torque transmitted to the fan blade under the conditions you describe is actually quite small. Yes, it's easy to hold the fan blade stationary; I've done it. A much more sensible means of determining if the fan and clutch are operating well is to CAREFULLY place your hand in the...

Why not drill two holes diametrically opposite each other not too far in from the race's OD? From the casting side, obviously. The drill bit tip will spin helplessly against the super-hard race, but no matter, you know how to sharpen drill bits, right? A good stout drift will then drive the race...

We used to call that "F.M.". Anything unexplainable to do with rubber, which is magic stuff!

There should be a hole cast in the diff. housing corresponding to the pinion inner bearing outer race. Usually, it is big enough to provide a narrow edge of the race exposed to a good, square steel drift. The drift is used to get the race loosened away from it's back side, after which it may be...

Tire pressure varies with temperature. With good, well-sealed tires, the pressure on cold mornings will be lower than normal, higher with rising outside temperature, and may amount to 3-6 psi back and forth. This principle is commonly called Gay Lussac's Law. See: Gay-Lussac's law - Wikipedia

When punctures are absolutely ruled out, by dunking the tires in soapy baths in semicircular tanks made for the purpose, stem leakage, rim leakage, or wheel cracks are the only other leak places possible, other than porous rubber (very rare). Stem leakage may be around the stem/wheel interface...

"Blown in the wind.......".

Saw this condition once, in all these years. Decided it was caused by intermittent non-contact between starter motor brushes and burnt commutator. Confirmed on disassembly, turned commutator in my lathe, good again. Hitting the starter "jiggles" the brushes, re-establish contact.

I can tell you the best thing I ever did was to retire. Lots of guys want to wait to get the most benefits. Unless you can tell the future, accurately, you have no idea of what tomorrow may bring. I took S/S at 62, 16 years ago. Last year at Christmastime, I suddenly experienced shortness of...

Are we getting enough young guys adequately interested in the skills to slowly replace us, ya think? Maybe EVs will eliminate ring & pinion gears altogether!

Good work! For general information, the Bendix spin-out type drive went away in the mid-60s. Gear is engaged by movement by a big solenoid now, a one-way clutch avoids engine-driving of starter upon disengagement, or stuck in engagement.
