'86 F250 Progress
I serviced both the front and rear differentials. The rear is a 10.25 with 3.55s and of course the front is a Dana 44 split axle with 3.54's.
The rear diff cover leaked a fair amount. From both the front and rear.





I barely got the fill plug out.

After taking it to the parts wash.

Cheap coat of paint.

I used a Fel Pro Gasket and Permetex Grey sealant.


Making sure the vent wasn't plugged. Which it was.


Temporary hose on it so I could move it around at the time.

The yoke on the rear axle leaked and was very loose.





After tightening.


The gear oil for the 10.25. Valvoline 75w140. I believe I used the two quarts of regular Valvoline 80w90 for the front diff.
The issue was with the turn signals. I would hit the brakes and the front driver side turn signal would light up. It would so do something funky with the brake pedal pushed as well as when the marker lights were turned on.
The end of the story is found in the following pics. I was so happy to find the issue.
The turn signals didn't work right as I stated above so I bought a new turn signal switch. The key had to be turned way forwards so therefore I knew the lock mechanism was messed up. I also replaced the igntion switch for safe measure. The windshield wipers would not work either. So I bought a new switch and a new motor. Turned out the motor was siezed up. Pics off all of this below.


Found a nest of some kind below the speaker.

Not a very good pic, but the two wires with bare spots on them someone wired togther. This was for the turn signal switch. I guess something in the switch gave out that supplies power to the brake lights and so they tied into the turn signals. Or something like that. But it was a pain in my rear for about 4-6 hours that I spent looking for the issue.

The turn signal switch has to be depinned to be removed and the new one has to be depinned to be installed.





New ignition lock assembly.

Everything on the column finished and ready to go back together.



I also scored a cluster from an '85 F250 with the 460 from a local salvage yard.

How the interior looked after getting it back together.

I installed it at this time but couldn't get the tach working right. I tried reading on here but I tend to over complicate things and it just didn't make sense to me on how to wire it up.

It also had this rigged up handle. So I put the right one on it. Also from a salvage yard.


I still needed a tach. So...



^^^ That is how it sits today as for the interior.
Cowl removed for the wiper motor to be replaced.




Cowl back on and windshield wipers working flawlessly.
But Nooooo!
... they had to hide it up inside the column shroud.
I am SO glad my truck is mine.

It is all too easy to get PO'd at the PO
I had a few choice words to say when I found it. I have found quiet a few things on this truck that someone done to make things harder for me. The real kicker was they tried to remove the steering wheel to replace the switch but stripped the steering wheel puller screws out. So I had that to deal with as well.
This truck actually used to belong to Midwest Sheet Metal Co.
It might take a minute for your eyes to catch it but it's there.




They also made the storage bin or whatever you prefer to call it behind the driver seat. Pic was taken before I cleaned the interior. It was pretty dirty when I bought the truck.

Whether they did the work on the truck or not I don't know and it doesn't really make a difference to me or not. I'm just glad it's mine now.
In the summer the bed and cab is coming off, getting painted and fulley repaired. The engine, transmission and transfer case are also getting removed and the engine bay and fenders painted. I will probably just replace the fenders.
Keeping the T19 and 1345. Rebuilding both. Rebuilding the 460 and would like 300hp out of it from the current 235 that they were reported as having.
I also want to go to a Dana 60 solid front axle.
Deck the block. Get quench and compression at the same time.
Remember, there is no replacement for displacement!

The current engine I have paper work on from Jasper engines. It was rebuilt around 6000 miles ago. Still yet. I don't trust anything unless I do it.
I have a timing set for it just haven't installed it. I will when the 460 comes out. I have a new Gates water pump too come to think of it.

I think the 4 bottles of Valvoline synthetic 80w90 along side the pump was for the T19.

I removed everything from the column. The key turns a part with teeth all around it but there are flat spots on opposite sides of it that I had to line back up. I took all that stuff out, stuck it in the parts wash, put some fresh spray silicone on it before reassembling. Starts like a new truck.

Big difference in how the ignition lock works in the cold eh?
I will check into it more before I use it for sure.
I really haven't noticed any difference with the lock in cold weather compared to when it's 60* or so. I have started it at 5*F with a windchill of -17*F and that's the coldest so far.
