Ford Ranger / B-Series :: 1986 - How To Disable Front Differential
Jun 21, 2015
My front diff is busted, and I mean bad.. I can barely even run the truck 5mph, and it's very loud. The diff casing is even busted. I want to just disable it to drive in 2wd. What's the easiest way to do it? It won't disable using the push button control.
Can I just remove all the locking stuff in the front wheels, so there's nothing for the axles to grab on, and manually turn the solenoid at the transfer case to shut off the front wheel axle?

Thought I would try and fill up the front. Diff well not as easy as the rear diff. They make a special hose or some thing. To put in the bottle so u can get some Gear oil in ?

I have heard from a few people that it might be the computer that is messed up. Just replaced cap and rotor, spark plugs, wires, fuel filters. Pump turns on. Cranks and cranks but won't start. Took the intake cover off and tried starting it, all it did was back fire. Checked the firing order and everything is right. So im left with guessing at the computer and ignition??

1986 Ford Ranger / 2.3 EFI / 140 CID OHC /4-Cyl/5 speed
So the last time I was here, I was having doggy issues which I thought were fuel related. I'm still having issues, although it appeared to cleared up a bit.
When I start the engine, it cranks over, I'd give it some gas, it would rev up, then suddenly die, no matter if I pressed down on the gas pedal or not. After two or three times doing this, it would turn over and maintain a steady idle, then off I go.........
The problem now? Well, late today I tried to get it going, and after about 15 times, I gave up. It would not stay idling, it would crank over then die. I did not want to ruin the starter. It seems the gas pedal is worthless after the engine decides to conk out, and no matter how many times I step on the gas pedal, nothing happens.
Has been replaced within the last few months:
Fuel filter regulator,
Inline fuel filter,
Cap and rotor,
Lucas fuel injector cleaner,
ECC computer, and Fuel relay switches, (multi-function relay/connector switch)
Air Control Valve - Removed and cleaned.
Checked all vacuum hoses.
Has not been replaced:
Map Sensor, (was told it's located on Pass. fender wall, but can't find it, according to the manual)
EGR Valve and sensor,
Throttle Position Sensor,
EVP sensor,
Spark plugs, (two years ago)
Plug wires, (two years ago)
Ignition control module, (replaced about six years, or more)
With trying to keep the gas going to turn it over, it does not, so to me, it seems to be more of a fuel problem than electrical, but I'm no mechanic.

1986 Ranger 2.3 inline 4
I just recently bought an 86 Ranger from a friend. It had recently stopped working and had no desire to fix it. So here I am. The truck will sit in park and rev all day long, once its in drive it idols fine and moves its self down the street. The problem occurs when I apply throttle. It begins to bog down and I cannot get past 20mph. I have replaced the fuel regulator and also I took the tank down and replaced the fuel pump. The fuel filter is two months old, and the throttle response sensor is two weeks old.

I have a 86 Ranger with the 2.3L fuel injected 4 cylinder and a 5 speed manual transmission. I can drive it for hours on the highway but if I get caught in stop and go traffic, it stalls and won't restart for about 10 minutes. When trying to restart it acts as if it is fuel starved. Spraying carb cleaner in the throttle body does make it run for a second or two. I was getting a code 18 & 67 before I changed the ignition module, now I just get code 67 or 11. I have done the following:
-Changed both fuel pumps, tank and frame rail pump (did one at a time, no improvement)
-Changed all fuel filters (in line filter, fuel reservoir filter and tank filter)
-Changed ignition module on distributer
-Changed both relays that control fuel pumps
-Cleaned battery terminals and body ground connections.
-New gas tank fill cap
I'm at a loss now as to what to do. I have been checking the codes with my multi-meter. I do not have a OBD1 diagnostic tool.

My pops has a 86 ranger with a 2.9. And what its been doing is, it will start up just fine then u give it a minute and itll start to run very rough like a bad miss fire, then if he revs it up for a bit. It will clear out and then run just fine until he starts it up again and it seems to do it more the colder it gets and it smells very rich. Iv checked the injectors and there fine, what other things could it be ? O2 sensors oorrr

I have a 86 ranger 2.9 5 speed. A few days a go I replaced the front fuel filter and all seemed ok. Last night on my way home the truck quit and I had to have it towed home. Now I find both pumps don't seem to be working. What would make me loose both pumps??

Looking for the wiring diagrams for 86 ranger fuel system. I replaced the fuel pump relay after testing and finding that it was bad, still not getting fuel. I want to test any fusible links or anything else that could have gone wrong before I throw another part at it.

I've got an 86 ranger sport and I'm having trouble with the lights. The turn signals work, and ALL 4 bulbs in the back are new. The brake light fuse keeps blowing, and the fuse for the tail lights is good but they won't come on at all. I was told there was a direct short somewhere, does that sound about right? And is there a common place where they tend to short out?

I have been hauling a lot of garbage with my 96 ranger this last week. The differential has been making a little more than usual noise like growling, but it has always been smooth, now all of a sudden it shakes like a tire out of balance up to about 55 then it is like a switch is thrown and everything quiets down and the shaking goes away, until i get around 55. I haven't climbed under the truck yet just checked the tires and grabbed the drive line they are all ok,i don't see any leaks so it is a head scratcher. Hopefully it will be something easy, but it hardly ever is.

I have A 1986 ranger with a 2.9 v6. I am thinking of doing a diesel swap and I am wondering what engine and trans combos would work best for this. I was thinking 4bt but there are may other options that could work.

But here's too my question. I recently bought a 2wd Ford ranger 2.9 automatic. Bought not running. They said it wouldn't turn over that there was something wrong with the starter. I figured it was the neutral safety switch turned out it was there's a wire broke on it. I can get in there touch the wires together and it'll turn over. But I can't fix it because the shifting linkage is In the way. I'm wondering how too take it off. I've never worked on one before. And I don't wanna mess up my gears.

its 1986 Ranger with a 2.9L V6 Auto 4x4, well to start with it seriously over fueling also it idles very roughly and even stalls out sometimes, when I'm trying to hold it at a speed it acts like it is missing (I guess that's from over fueling as well and it also pukes out lots of black smoke, it goes through way too much gas for a V6), but when I speed up fairly hard it acts fine until I try to maintain speed again, I have already put a tune up into it and a new EGR as well a fuel regulator and how to fix it?

I have a really nice 1986 Ranger XLT with a 2.9 V6 (injected) and OD Automatic with about 135k miles. I've had the truck for over ten years and have been pretty happy with it. I'm still trying to correct a couple of nuisance items:
1. Sometimes it runs smoothly, and at others it has a rough idle, and once in a while it will even stall. Before it stalls, it idles or runs roughly, and will miss erratically. When it quits, it does not fade out like it is running low on gas; it quits suddenly, like the ignition is turned off. If I am driving at highway speeds, sometimes it will buck as it misses, and sometimes stalls out. But it always starts up right away afterwards. This does not happen often, but when it does, it happens several times over hours or days, and then goes away by itself for months, even years, and then comes back for another round.
I was hoping whatever was wrong would totally fail, but it has been several years and is not getting better, nor worse. Fuel mileage varies, too, from 16 to high 20's MPG. I have new low- and high-pressure fuel pumps (dual tanks), new gas and air filters, checked all the electrical connections, put in a new ignition switch, new O2 sensor, Air Flow sensor, EGR, replaced all the vacuum lines, new battery and cables, new starter, all new electrical relays, fuel pressure regulators, new fuel pump inertia switch, tuned up engine (incl. wires, cap, rotor, ign module, plugs and timing), and cleaned out the already sparkling-clean tanks.
2. My oil pressure will drop at idle to low-normal when the engine is warm. It never goes to below Normal on the gauge. I have replaced the gauge, sending unit, and oil pump. This is a long-term issue, and is not getting any better or worse.

Rebuild on the Mazda 5 speed transmission. My 1986 Ranger 2.3 Four cylinder has 280,000 miles and the clutch has never been replaced. It's not slipping but I'm having trouble getting it into gear from neutral. Was told that the release springs on the clutch plate have weakened causing the clutch to not release completely so figured it's time to replace it. It's done well the last 280,000 miles. The question I have : overhauling on one of these Mazda trans and how difficult was it. Any special tools required, etc...I see Autozone has a rebuild kit which appears to have bearings, seals and gaskets. Figured while it was out I would go ahead and rebuild it myself if I can. Rebuilt a few engines but never touched a trans.

My 40 Ford pickup is on an 86 Ranger chassis and uses the stock Ranger steering gear. My question is about the connections on the steering box. I'm using a GM power steering pump and several steering gear vendors have told me that outside of needing to adjust the pressure for the correct feel, the combo works. I fired the truck for the first time tonight but the steering wheel went crazy, shaking around and finally spinning on it's own to a hard left.
Some quick research leads me to believe that I have the lines reversed but it would be great to know for sure. I did manage to find on e diagram of a Ford PS box on Google and it shows the lines reversed of what I have set up on my truck and I can't for the life of me remember how I figured out what the plumbing should be when I installed it. Which port on the box is the inlet and which is the return?

The rear axle in my dads 1998 ford ranger has been vibrating for quite a while so I pulled the cover today and found that the fluid was full of metal shavings, it was glittering. I also found this metal chunk in the differential so my mechanical experience tells me this is not a good thing. I am taking it apart tomorrow any tips or do's or don't? Also, what this metal chunk is and what that knurled up end is??
Door tag told me it was a 7.5 open 4:10 axle.

My 2007 3.0L XLT 2WD Ranger with 7.5" traction-lock differential started making expensive noises last weekend coming from the rear end. Shop has not yet opened up the differential because the initial though was just do a swap.
Turns out that 7.5" LS is hard to find, plenty of open diffs available. So I suggested that I'd rather swap in an 8.8" LS rear end anyway but turns out that these are also hard to find. Was a LS rear end option just not very common? or do these get scooped up just as fast as they become available?
