Ford Transmission :: 1989 F150 - Rear Differential Rebuild?
Aug 30, 2010
I have a 1989 ford f150 xlt lariat it has a 5.0 and a 5 speed and is 4 wheel drive. Any way I am looking into rebuilding the rear end of the truck the pinion shaft has a lot of play in it up and down and both outer axle bearings seem to have lots of play in them. I believe it is a 8.8 inch in the rear. Just wondering if there hard to rebuild or what it all entails I have never taken one apart before and want to know what I am getting into. I have access to a press and a pinion and carrier bearing puller. the axle bearings i have done tons of them but never had to pull out the carrier. wondering how to set turning torque and backlash etc... and torque specs for everything.

My truck (02 7.3L cc) started making a grilled ding type of vibration when I would let if the throttle. I felt the axle going into the rear differential was a bit loose, so I took the cover plate off. The pictures below show where the pinion I think is hitting, sort of like the bearing is allowing front to Rear differential scaring from movement. Rear movement.
How difficult is a rebuild, and is there anything I should be careful of?

My 2004 Ford F150 only has 20,000 miles on it but makes a shudder from stop turning left or right. I asked the dealership about it and was told that it was likely the clutch pack in the rear differential sticking. I was told I could try changing out the fluid while also adding a few ounces of some special lubricant. But, they said it wasn't a guaranteed fix. Apparently, they have tried this fluid change and drive the vehicle in figure 8's trying to get the lubricant between the plates. They also said that this was a known problem to Ford. Lastly, I was told it wouldn't hurt anything to keep driving it. I checked some other online forums for Ford F150 owners and this does seem to be a recurring problem. I'm thinking about having the clutch pack replaced but obviously hate to spend the money if I don't have to.

I have a 89 f-150 xlt with what i believe is the m5od (4 speed with O.D) transmission and the 5.0 motor, the trans has been whining since I've owned the truck and it started popping out of reverse on me a couple months ago, now i have to slam it into gear to make it go anywhere even when I am going down the road! The clutch is fine but the trans is hanging up, anyways i have a granny gear transmission a buddy of mine gave me out of an 85 f150 that had the inline 6 if i take the bell housing off of my transmission can i put the internal slave cylinder on that transmission? Will it work or will i have to find a way to put an external slave cylinder on it?

I recently bought a beater '89 F-150 (I-6, MT) with the following problems:
1) Both rear brakes seem to stick on occasion--almost like there was a "check valve" on the rear brake line. When that happens, there is a "BRAKE" and "Rear ABS" light (although the light does occasionally come on without brakes sticking noticeably).
What I noticed in Haynes is that the "RABS I" system functions in the following way: a) Upon noticing rear axle spinning slower than front axle, it actuates a valve, isolating the rear brakes b) If the problem persists, it then dumps the pressure back into the main system.
So, I wonder: Is this an ABS system acting up? If I were to (temporarily) de-power the ABS setup, would it default to "no ABS," or would I need to remove the hydraulic valves from the brake lines? (Don't really want to if I don't have to.)
2) You can select either fuel tank, get that tank's level to indicate on the fuel gauge...yet it only "draws" from the front tank.
Again, Haynes says there is a low pressure pump in each tank, feeding a high-pressure pump in essentially a small "header" tank. The "dual-function reservior" has a wholly mechanical selector, and notes that "Tank switching versus gauge conflicts can occur under certain failure mode conditions."
So: I can understand that the mechanical selector can, in effect, "stick" on one tank. But what I don't understand is how it can still draw from the front tank, with the "rear" tank selected (and presumably, that tank's low-pressure pump trying to feed the header tank.)
Is it possible that the low pressure pump--while beneficial to prevent gravitation at the main pump--isn't strictly necessary to fuel the engine? Or do I have a problem with a low pressure pump that's "always on," regardless of the selected tank?

I recently changed the rear diff fluid on my 1999 F250 Super Duty (180k) It was due plus I was getting some chattering when making turns from a stop. The Diff fluid had about 60k miles on it and seemed to be a little low even though I don't see any leaks. I paid to have it done last time so I can't say what kind of a job they did.
I used Motorcraft diff fluid and 8oz of friction modifier. Two weeks later and about 500 miles, today I noticed on two occasions when turning a moaning sound coming from the rear of the truck. Could this be a sign of too much friction modifier and the cluthes are slipping or is something else going on?

I'm a new owner of an '89 F150. It's a four speed manual trans, 4.9L 6cyl. This is my first truck and I bought a beater in hopes of learning while I fix it up. I have minimal experience (biggest repairs have been replacing disk brakes on a previous car and replacing the EGR valve on this truck), but I want to learn more.
The truck has a bypass switch and the forward fuel tank was removed. Both of these modifications occurred before I owed it. Also, the clutch is a bit grumpy. Sometimes I'm unable to get it into first (I usually "granny start" from second), and every once in a while it doesn't want to go into reverse.
When I bought the truck, it would just choke and cut off after driving for 30 minutes or so. It would restart after cooling down. My mechanic said it was a problem with the fuel pump and replaced it, and that fixed that problem.
After that, the truck began to have trouble starting. I would flip the bypass switch and the engine would rev up, then drop RPM's quickly until choking off within a couple seconds. When I flipped the switch again, it would start up fine. It would run fine after that.
A mechanic recommended having the fuel injectors cleaned. The fixed the problem for about a week, then it started again. A friend of a friend who has a home garage suggested a vacuum leak, and we found a leak in the EGR value, which we replaced.
Replacing the EGR valve fixed the problem again, for a couple days, but it came back. Meanwhile, immediately after the EGR valve was replaced, a new problem started. Periodically while I'm driving (I haven't been able to detect any pattern), the engine will just shudder or choke a bit. It feels like it's threatening to choke, but it never actually does. Once it starts, it typically does this every couple seconds until I shift gears.
I'd really like diagnosing what might be causing the choking when it starts and the new shudder when driving. I realize it could be a number of things.

I was wondering should I find metal in my pan after a rebuild on my AOD? It's been about 4 months since the rebuild and i took it in to have the fluid changed at another shop. Now the unit is doing fine but I did let the shop that did the rebuild know what was found.

I got an old 1989 F-150, manual, in-line 6 engine, with an 8-foot bed. I use it for hauling landscaping equipment, as i am starting a business. i will likely start hauling trailers with it this summer, but I also just want the engine to give me more power.
What are some things I could do to up the HP, or a better truck in general. I'm not looking to make it into a 350Hp monster, just get a little more out of it. What can I replace or add that would do this?
First, the idle dies on me when i put it in neutral, or gets stuck at 2500rpms. is this a vacuum leak, or the idle-air control valve?

Ford AOD in 1988 F150. It's my first time rebuilding a trans and after install will not roll in neutral. I guess this is part of the learning process but I really need to get this fixed.

I rebuilt my 4r100 myself. 1st time I re-installed it, I had no 2nd gear. All other gears worked fine. Drove it less than 2 miles.. slowly..
Took it back out, found i built the Intermediate Clutch wrong. Fixed. At the same time, found a stuck valve in the accumulator VB, Fixed that, at least i think I did. all the valves snapped back under spring pressure.
Put the trans back in, Drove forward, all forward gears work. Drove 10 miles normally, w/ some time spent in all speed ranges. Temps good, outside temp was 73F
M1 = i get good engagement and engine braking
M2 = I get 1st and 2nd, seems normal
OD = Normal shifts, 4th is a little soft, but always was.. TCC lockup good
OD (Cancelled) = Normal 1-2-3, with lockup in 3rd Worked the button multiple times, shifts down, and back up normally.
N = No movement, no creeping.. Normal.. as far as I can tell.
R = No reverse, or is binding in reverse, not sure. worse when up to temp.
P = Normal, no learching or creeping.. No stalling.
The OD light never blinked, so I don't think it is electronic..
Since M1 works and holds with engine braking. L/R clutch and seals are ok. Forward clutch is ok since i have ALL forward gears, No slipping that I can tell. no creeping in Neutral, so the clutches are not fried.. New fluid is still perfect. I'll have to re-pull the pan to see if there is anything on the magnet. I think it could be some stuck valves in the VB also.

Pulled transmission out and it needs to be rebuilt front to back. My motor is generally stock but I'm rolling on 37" tyres so I'm thinking a stall converter and a "performance" rebuild. Looked at "Monster in a box" from Monster Transmissions. Truck is used at tymes to haul cement and heavy bed loads.

So last night my trans have out, going up a slight grade, all of a sudden the engine revved and I had no more 3rd gear. I've done some research, looks like rebuilding it is the only option. I've got my Mustang GT to drive in the meantime, so I am thinking of rebuilding it myself. The truck is an '07 F150 5.4 2WD.

I have a e99 7.3. had the transmission rebuilt a couple weeks ago by a local shop. have been getting some hard shifts between 2nd/3rd when lightly accelerating. Took it back already but they couldn't find anything. I am planning on taking it back again but what it is so it gets fixed right. What is causing this or what it might be? Should I be worried about having this shop try and fix this?

I have been having transmission problems in my 2005 Ford Escape due to my torque converter coming apart so I took it to a local transmission shop for a rebuild. After 2 days it was ready and I took it home today. I put it in reverse once and it was fine but the second time I tried to back out of my driveway it won't go into reverse. It will go forward though. His shop is closed and I am going to take it in tomorrow morning. I have a warranty but it says I am responsible for labor. Is this something I should have to pay to fix if it happened the same day I picked it up?

I have a 1997 ford ranger 4x4 5 speed manual. We are rebuilding the transmission ourselves, and taking on the task has been pretty hard. We are stuck at the input shaft. How to take the input shaft out? Do you need a special tool?

Transmission rebuild? I seen a few threads where people talk of it but no follow up. I've heard it takes special tools but then so does a lot of things we shadetree on our own....
