I'm looking at a 1965 F100 as a project car and it is listed as having Twin I Beam.
As I've had nothing to do with Ford trucks before I'm wondering if someone can give me a quick run down of what it means.
Thanks,

It is basicaly a straight axle that is split. The two halves attach about 3/4 across the front end making the front independant suspension. Picture two swing axles. Does this make sense??

Twin I-beam is a great/durable suspension system. Correctly aligned they will stay aligned forever. Ford used this setup from 1965 till 1996.

Thanks Stuart.
I can picture it yes but certainly different to what I had as my perception!
I will now know what to look for when I check it out this weekend.

Stuart gave a pretty good description. It will be obvious when you look under the front end and see it. I think they are a great front end setup too.

Let us know if you get the new project.

Take a close look at the inside tread on the tires.

Ken,
While your under there, also look to see if the kingpins appear to have been greased lately. That may give you an idea as to the level of PM it's been getting. Changing out kingpins can be a real bear!

I think I'd consider taking along a floor jack and jacking up each front wheel so you can whiggle each front tire in & out at the top & bottom (NOT from side to side, side to side will determine tierod ends condition, not the kingpin condition) & determine the amount of "slop" at the top and bottom of the spindle/kingpin. If the spindle/kingpin bushings are worn out to the point of the kingpin wearing the spindle oblong, that repair will certainly "leave a mark" in your wallet! Whatever you determine, calculate the results into your final offering price.

Good Luck!
Ryan

I believe that 1965 was the first year for the Twin I Beam on Ford pickups, prior to that, cast iron I beam "straight" axles were used. Checking the king pins for wear is a very good idea, it is not a fun (or cheap) job to have them replaced. With regular grease jobs, the king pins pretty much last forever.

--- You are correct, Rory.


...prior to that, cast iron I beam "straight" axles were used.

--- Which gave you a ride VERY similar to 1958 John Deere tractor!

Thanks for the advice guys.
The photo really helped, Paul, thanks.
What an uncanny analogy - the bumps and thumps it made were just like my father-in-law's Fordson Super Dexter!!!
Too much movement and slop for my limited mechanical aptitude so I'm still looking for a project.
Thanks for the help.

Old ford trucks are great and have a strong following. Don't be afraid to get one that needs a little work, they are easy to work on, parts are easy to find and cheap, plus pretty much the whoel drivetrain interchanges up thru 1979. I just got done restoring my 65, it has a 351W/C4, 9" rear with 3.25's, power steering, power disc breaks, and some other goodies. Lots of fun.

P.S. I knocked out the old kingpins, installed a set of disc brake spindles, and put in the new kingpins in about 30 minutes. Some trucks are more stubborn than others, but its nothing to be afraid of.

The front suspension components from 1965 to 1979 will interchange. This means you can swap to front disc brakes and power steering with factory parts. The only fiddling will be with the steering column if you swap to power steering. You will need the (shorter) steering column from a 1967-1976 truck, The '77-'79 columns don't have a tapered shifer collar and use a plastic filler to fill the gap to the dash which won't fit the '65 dash.

And by all means swap the single master cylinder to a dual master cylinder.
