Ford Transmission :: 1979 F150 4x4 - Slight Clanking Noise In Front
Jun 24, 2012
I used my truck in 4x to pull a couple of little stumps. Nothing major, just put it in 4l more or less to keep from tearing up the yard. Noticed a couple of weird things today. For a minute had a good pull to the right. Just felt "weIrd" in front end. For lack of a better explanation. Jacked up and checked for play, nothing unusual. Took off the tire and checked other stuff and couldn't find anything. Lubed up joints etc and drove later. I'm hearing a slight " clanking" noise in front. I know it's got something to do with the 4wd but I don't know where to start.

I am looking to change out my manual transmission in my 79 f150. I want to put a 5 speed in it but still keep my manual clutch. I have a 300 engine that I also want to keep, can I just put a late 80's early 90's 5 speed transmission in it and keep my original bell housing?

79 F150 400/C6 2wd. Loss of reverse and it doesn't want to stay in high.
Strange thing happened today. I took my truck on it's longest test drive since rebuilding the transmission. It was about 25 miles. I got to the junk yard just fine and it was running just fine when I left. I went through a drive through to grab a burger and headed home. That's when it started acting funny. It shifted fine 1st to 2nd, then 2nd to 3rd, but it wouldn't stay in 3rd. It would shift into high, but the slightest bit of throttle and it would shift back into 2nd and eventually got so bad that it just stayed in 2nd, so I had to return to the town I was leaving.
I drove to an autoparts store nearby. I decided to move where I was parked and when I put it into reverse, nothing was there. It rolled back. I drove it to the new spot and called for a tow truck. Weird thing is that reverse worked just 10 minutes earlier when I left the junk yard. When I got it home 2 hours later, it backed up under it's own power. I let it cool down completely and took it for a test drive and it drove perfectly. I have a few theories or questions:
Kickdown rod: Can it be in such a position that it could take away reverse? I would assume that if the spring wasn't returning it all the way forward that it wouldn't have shifted from 1st to 2nd properly. I ask this because I am not using the Holley spring mount and I'm wondering if the wrong spring set up allows the kickdown to be partially activated.
Fluid: What fluid are you suppose to use after a rebuild and what fluid can't you use. Mercon V says it supercedes earlier fluids, but is that wrong?
Am I wrong to assume that if fluid was the problem that I would have had problems with 1st and 2nd?
Cooling: What are signs of hot fluid other than smelling it. Once again, assuming I would have problems with all gears if fluid was too hot.
My guess is that something is sticking in the valve body, but before I drop the pan and pull out the valve body, I want to make sure all other avenues are exhausted.

It's a 2003 Ford F-150. When I'm driving slow I hear what sounds like a tin can clanking up against another piece of metal, coming from the rear end. Right, Left, or center I'm not sure. U-joint maybe?
There is also a bit of wobbling when I'm braking at a high rate of speed.

I swapped in a manual trans in my 79 f250 4x4 about a year ago. i had the trans gone through before i put it in. I installed a new luk clutch, resurfaced the flywheel, new throw out bearing, etc.
Ever since i installed it there was always a clunking noise in the trans. I drove it and didn't think much about it until recently where im just fed up with it. the trans always shifted nice and tight with no grinding.
In the past few weeks i picked up a parts truck for the trans thinking that's what my problem was. I drove the truck before i pulled it and it mad no noises whatsoever. I had it gone through and reasealed it before i installed it. I pulled my old trans and it still looked good with no slop on the input shaft(which i thought that was the problem). I installed the new one and once again same noise.
I decided to pull the trans again this time pulling the bellhousing and checking the clutch. It looked like new to me still and i saw nothing abnormal. Put it back together and still the same. I swapped the transfer case too, checked both driveshafts all is good. I am thinking its coming from the bellhousing(maybe the clutch is bad)
So here is a video and you can hear what I am talking about it happens mostly when I engage the clutch and i am coasting. it is much louder now with no carpet and the trans hump cover off.

I have a 1979 Ford F150 1/2 ton P/U XLT, 4WD 6.6L 2BL OHV 8cyl that I'm trying to put A/C back in. The truck had factory air, but the evaporator is the only original part in this setup (along with the controls inside the cab on the dashboard).
The new compressor is working. All the pressures look good (the low side is around 35 to 40). But we're finding that the air out of the vents is only dropping 20 degrees max. We've checked to see if the blend door was not working and it was getting heat from the heater core. We blocked off the heater core completely with the same results. It just doesn't seem to be getting cool enough. The large fittings on the firewall should be cold (maybe 40 degrees), but it's only cooling to about 79 degrees, about a 15 degree drop.
We cannot see into the evaporator box to see if there is an expansion valve in the system, but we did not put an expansion valve in with the new system we put on.

1979 ford f-150, 460 w/ 4bbl. Carb recently rebuilt by professional, but on cold mornings (in particular) runs rough even after a little warm (just like me), like the choke isn't clicked or clacked (couldn't resist) off. Can the choke flap and mechanism be gunked up, needs some cleaner applied?

This is an Auto/4z4/4.6 V-8. It's Skidding or a Clutch is not holding at times when shifting up or down while on Cruise and slight hills.
someone suggested changing oil and filter about two years ago. I did that and it didn't change a thing. $145 that time.
I'd like to know if its the clutch in the torque converter, or the Transmission? If I have to change something out, should I get both?

Ok I'm new here but I'll keep it simple. Driving around nyc (crazy winter weather lately) car started making a clanking noise every so often from the hood. (note it was getting harder to steer i have awd) Pulled over, it looked fine, kept driving, all of a sudden few blocks later a LOUD metal clashing noise came from under the hood. Pulled over turned the car off. Now the car starts fine, but the car makes that noise every time i shift to Forward/Reverse. Neutral is fine. Tranny went out? The car wont move....

I have a '79 F150 4wd and was wondering what would indicate a caliper needing replacement. I'm already going to replace everything on my rear brakes, they are completely trashed. However, the fronts seem OK, NO indications of leaks or seizing both sides of the rotors appear to be evenly "used" I guess. The inner pads do seem to be thicker than the outer pads is this normal? Anything I should be specifically looking for before I have the rotors turned and put a new set of pads on?

So My 2002 only has 27k miles so I'm hoping it's nothing out of the ordinary. I understand that the transmission will make some noise in shifting but I'm noticed a pretty solid "clank" when I shift especially from Park to Drive or Park to Reverse. Just wondering if other drivers have a similar experience? I remember my last car had a sort of "ratchet" sound in shifting and I've grown accustomed to this "clank" now, but just wondering of others have the same clank? If not normal, what should I look into? Also before it's recommended, I know it's not the brake caliper clips as the "clank" occurs before actual vehicle movement.

I just had some H&R springs installed and my front suspension is making a funny noise.
It sounds like the front springs are clanking around..

Two months ago I started getting a clanking noise from the right front when I accelerated from a stop, or stopped and moved the car backwards from forwards or vice versa. I pulled the wheel and noticed pretty work brake pads, with the inboard pad completely shot. Car has 34k miles. The left side inboards and outboards were about 50% worn and were worn evenly. Sure enough, I had a sticking lower slide pin on the right. I cleaned everything up and lubed all contact points, and replaced pads and clips. I removed, cleaned and re-lubed all slide pins and holes with the appropriate silicone brake lube, and confirmed that they are siding freely. The problem is that this worked, but did not completely eliminate the problem. The noise still happens about 1 out of every 5-10 starts once the car starts to roll after the brake pedal is released. The rim seems to rotate ok when jacked up and I am not getting a pull. A mechanic buddy of mine said that in these cases he just ends up replacing the whole caliper.

I just put on some new wheels and tires (19" VMR RS4 reps) and there is a weird clanking noise coming from the front left wheel when I am going around 10 mph. It doesn't happen when I'm moving faster, but I have checked it out and don't see anything rubbing or hitting any metal pieces. Could it be the suspension or something else? I haven't heard it around any of the other wheels.

I've had a fuel leak near the pump of my 79 F150 with a 400 for some time. I didn't know exactly where it was coiming from, but fuel was being sprayed on to the oil filter from something near the pump. I assumed it was the steel line, and that it had rusted through or cracked, and was going to replace it when I had a chance. I was poking around today though, and realized that the fuel was not leaking from the line, but from a hole in the side of the mechanical pump.
For someone who knows what these pumps look like, there is a horizontal cylindrical bump out near the top of the pump, on the side of the pump that is away from the engine. The fuel is spraying in a mist out of one side of that. To me, it always seemed to be a screw channel, but I didn't think the pump was 2 halves put together? Need to know more about my pump, what that bumped out section is, or why/how fuel could be spraying out of it.

I drive a '96 Infiniti I30, and recently the driver's side front wheel has started making a mysterious noise. It's not a grinding but a clicking/clanking noise. It's only present when I'm turning and accelerating. If I let off the gas it disappears. The other strange thing is that i can feel it in the gas pedal. I looked at some other discussions and the only thing that was similar was a bad CV joint. One last thing, if it is the CV joint how soon should i get it replaced?

Bought a used 1997 Lariat Supercab 5.4L last week. It was missing its front drive shaft so I want to install one.
I just ordered a used front drive shaft online but I now need the bolts that connect everything together. New drive shaft has all the flanges, etc.
What is the pitch/length of these bolts? The part number for the bolts is N800594-S100 (AB-308-D). I believe there would be 8 of them, 4 on each side.
I thought it might be easier and cheaper to just buy bolts from an aftermarket supplier instead of OEM from Ford.

So against my better judgement I rebuilt my C6 myself. It's all back together and in my 79 F150 2wd 400cu. It seems to not want to shift into 2nd on it's own. I can manually shift it into all the gears but 2nd feels like it slips. So here is a list of parts with questions:
I used Mercon V instead of Type F. The transmission is a 1987 and the bottle says it covers vehicles requiring Dextron/Mercon.
I installed a FF servo lever with a P servo. My kit didn't come with a new spring. What effect would a worn spring have?
When adjusting the band, I set it to 120in/lbs and backed it off 1.5 turns. This seemed very loose to me. It leaves the set screw finger tight/loose, so I tried turning it in 1/2 turn but that made no difference and I won't drive it until I readjust it. Also it's a RedEagle wide band, but that shouldn't make a difference.
One place I think I could have a problem is with the modulator. I didn't have a scale to do the 12.5 lbs method, but I had a big syringe, vacuum guage, tubing and t fitting. I could hold the -15" of mercury but the rod didn't go in to the notch like it said it should. I was going to stick the old one in but it's bent and the rod is missing. Will a bad or misadjusted modulator cause the tranny to slip in 2nd? I don't think it's inbetween gears because it does accelerate in 2nd.
I used the BadShoeProductions video along with a Ford Shop manual to assist me.
Complete list of replaced items:
New Modulator
F servo lever with P piston
All Friction and steels
Pressure plates for additional friction plates per video.
All Seals and gaskets
New wide band
New pump
Hughes torque converter
TransGo shift kit
New Sun Shell (Took my end play from .070 to .012)
Everything was cleaned and tested ok per video.
Then only problem with the video is it doesn't tell you what to do when you have a problem, only shows you how to tear down and reassemble.
I used a torque wrench for everything, but if it turns out it's a valve body problem then I will go back through it but only using a nut driver.
The kick down rod is working properly.
My gear selector is set properly.

This is a photo of my '79 F250 4x4 rear axle (Dana 60 full floater) this seal will leak in a few miles ..what I need is the part number of a replacement seal made like the one in the lower photo ..it seems that Ford no longer has this seal.
Notice the increased distance from the bearing to the sealing lip in this photo ..the sealing lip on the new seal in the upper photo lies almost on the bearing, this one just barely engages the seal surface on the axle stub. I can machine the bearing pocket deeper to cause the seal to move farther onto the sealing surface, but that would also cause the bearings to be closer together, and may cause problems there.
