wow pretty cool

[Milwaukee]

Yeah now I am get 18.75 mpg but it hate city traffic.

I believe I have couple bad injectors it have burnt fuel smoke when floor on highway.


I tried block radiator. That does work BETTER EXPECT oil pressure gauge keep flick zero psi but engine doesn't make sound.


How you found manual gear box for F250? mine is bad it drip power steering oil.


I really need alignment it badly.

[trooper Tdiesel]

if the steering box is a ford oem type, it would have to be from a early 70s ford or older if i remember right.
by the late 70s, 3/4 and 1 tons where P\S only please correct me if not righti think im right

Found the manual steering gear at a local wrecking yard.
I believe MS was an option through the 6th generation run at least (up to 1979) but I could def. be totally wrong.

If it's the same steering box as an F-150, manual boxes were available until about 87.

Recently came across a truck for sale that reminded me of this thread. Looks like a truly great deal at $5k (seems too low). For sale near Houston, TX:

I have a running 1988 Ford F350 custom crew cab rescue truck for sale. It has a strong 6.9L International Diesel motor with a 5-spd manual transmission. It has a custom made flawless aluminum cargo box worth a lot . . . A plumber or an electrician will find a lot of use for it since it has place to mount an electric generator with a fuse box and all sorts of connections and outlets all over the truck. Reasonable offers will be considered. Please call (832) 665 3568 for more pictures or information. Also, it has only 8000 miles on it since it operated on a small chemical plant and has never been used outside. Title is clean and has been owned by only one company.

1988 F-350 Rescue Truck with Box


The enclosed box is tall, relatively. Made me think of alternate ways to make money with a good home-made biodiesel truck candidate:

Mobile CNC Truck

Mobile 3D Printer Truck

A PTO-mount hydraulic motor can drive a generator AND a compressor. Add a heat-strip equipped A/C to the roof.

Once the new axle is on, bleed your brakes.

A complete rear end swap is much faster than a gear swap.

I wonder if, 5 years later, Christ, rmay635703, or elhigh are still on these forums?

I did end up changing the transmission, and left the rear end alone.

But yesterday, while bump starting the engine after EOC, the differential pinion (the part that goes between the transaxle and the internal gear) snapped off (!!!!!!!!!!!!!)

An instant later the differential locked up, so something must be broken inside as well, and replacing the pinion probably won't be enough.

So now I'm looking at replacing the rear axle afterall.

I suppose while I'm at it, I may as well get a taller gear ratio.

My question, if anyone happens to know, is which ones will fit properly (same suspension attachment points, hubs I can mount my existing wheels to, compatible U joint to the transaxle)?

It currently has a Dana 60 (or possibly Dana 70).
Probably (?) 3.73

There seem to be a number of axles used on F-250s with the same or better weight ratings.
Would I be able to put in a D70HD or D80 (from the 350 of the same year range), or a Ford 10.5 or 10.25 (from newer 250s)?
What else might be compatible?

I'm hoping to be able to just check door tags to tell whether a particular truck at the junk yard is a potential donar (though I suppose there's no way to get the gear ratio short of checking the case tag, but at least I could narrow down if it's even a candidate)

If you haven't found an answer yet, these guys will have one. I still lurk there from time to time a year and a half after trading my 93 7.3 IDI just because the "old timer" knowledge thrown around is interesting to me.

yup, thanks - I've got a thread at Replacement differential options (1984 F-350) - Ford Truck Enthusiasts Forums
and several people have given me lots of helpful information.
Still haven't found a solution, but they've got me on the right track
