I am noticing a whining noise with a pitch that corresponds to the RPM. Sounds like the noise you hear when it is in 4wd low. I am thinking it might be the steering pump, water pump, or an alternator about to go bad?

I have fuel seeping out around the fuel injector pipe where it goes into the fuel injector. I tried tightening the nut a bit, but it doesnt budge. Do I need a new pipe, or can these be repaired?

I parked my truck (86 M1008) last night and this morning I found a puddle of fluid that is leaking from the shield on the transfer case. I cleaned it up, but it keeps leaking. This evening it is still leaking. It isnt a huge leak, but there is a puddle of fluid that keeps reappearing after I...

I am having trouble with my shifter. Something seems loose in the steering column, and I cant get the transmission to go into park. It only gets to reverse when the shifter is in the park position. Nothing wrong with the linkage in the hood and by the transmission. The problem seems to be in...

I have a M1008 . Today when I started it cold, I noticed a small puddle of coolant on the ground. When it was still cold, I removed the radiator cap. Lots of flkuid came gushing out, and bubbles. I also noticed the reservior was filled very high. What is going on?

Hello, I just found my M1008 doesnt start and I feel that the problem is the glow plugs arent working. The light still works, but it stays on for much longer than it usually does. I checked the voltage to the relay and I read 24 volts (although I didnt disconnect all the glow plug leads.)...

Hello, I have a M1008 and my running lights on the tail lights are out. Also all of the dash lights are out, but headlights, brake lights, turn signals still work. The fuse for the running lights, #16 on the diagram, a 20 amp fuse, blows as soon as I flip the blackout switch, even with the tail...

Two questions 1) I have a 1986 m1008 with lifted suspension. The suspension was lifted when I bought it. I started getting some tire wrap and the straps on the rear leaf springs were popping off. I took it to a spring shop and one thing they told me was that I needed a block on the frnt left...

I was driving and heard a belt start squealing, then smelled burning rubber. Soon after the belt to gen 2 broke. I replaced the belt and noticed the volt meter went up to the beginning of the red. I assumed it was recharging the battery that must have been drained by the slipping belt. I...

I have a 1986 M1008 pickup.. When the motor is off, I can reach in and spin the fan with my hand. It seems to spin free. I it supposed to do this??? Or is something broken?

how do I adjust the brakes on my m1008 so it gets more from the front, less from the back. Now when I stop at every red light, my back wheels are locking up and I get angry looks from the guy in front of me who thinks I am hot rodding.

can somebody tell me what size the hex key is for the fill plug on the M1008 rear differential? I am looking to buy one. It doesnt seem to be a standard size.

Is there a special tool to remove the 30 mm plugs on the transfer case of the M1008? I cant get it with a socket. Its on there pretty tight, and the head of the plug is very thin.

One more- how does one adjust the vacuum modulator valve? My transmission on my M1008 has such a strong kick that I am worried about it knocking my neck out of joint.

On my M1008, passenger side of the transfer case, there is a hose leading to something that looks like a miniature vacuum modulator valve. What is that thing? Cant find it in the manual. but I dont know what it is called. Whatever it is , it looks like mine is ripped. Is that a vacuum hose...

My M1008 engine brakes in 3rd gear until it hits 35 mph, then it breaks loose and free rolls until stopped. In second gear, I dont get any engine braking. In first gear, it engine brakes all the way until stopped. Anybody know what is going on? I would expect to always have it engine...

I dove into the gen 2 light problem, expecting to find myself taking apart the dash. I started at alternator 2 on the passenger side, looking for the brown and red wires. When I touched the radiator hose that runs across the top of the alternator,over the top of the plactic connector, a big...

Starting Problem:Intermittent starting: I have a M1008 with the doghead mod. Sometimes when I try to start, I turn the key and get absolutely nothing. When it is hot in the cab (120-130 F), the problem is worse. If I can get it cooled down, and jiggle the shifter, then it usually starts right...
