What to do about it?

I am thinking of buying a 1969 F100 swb and I am wondering what kind of front and rear end I could put under it because the truck is poorly kept and I don't think the driving system can be saved. Let me know something cause I am new to these older trucks but always wanted one.

4x4 I assume... A Ford 9-inch in back and a Dana 44 in front... a bolt-in would be a 9-inch up to and including 1972 cuz in 73 the frame widened out by around two inches (IIRC). After that, then the spring perches gotta be relocated. In front, a Dana 44 up to and including 1979. Gotta sort out the steering and brake systems accordingly.

Ummm.. I didn't say that and that wasn't part of your original question.

I recommend you tell us the whole story... your goal for the truck I mean. What do you want or need in terms of performance, comfort and convenience, safety, etc.? Now tell us about your daughter's mechanical ability and aptitude. Will she be on the phone with you about every unknown tick, groan, or vibration?

Now what is your budget? I can recommend a Currie High 9 and a custom ProRock Dana 44 driven through a 203/205 Doubler or an Atlas II but I'd be wasting my time unless I have more clarity.

I haven't decided between 4x4 or 2wd yet but I lean towards 4x4 simply cause its so handy. Either a 351 or 302. Im going to put seats outta my 97 in it if they'll fit. id like to put the gas tank under the truck and id like to use the newest driveline I could for parts availability. Idk how inclined she'll be cause she is only 5 so budget not much of an issue. Iv thought maybe a crown vic frame or a f150 frame swap but like I said I usually only mess with newer trucks. but if it would be easier to swap parts id prefer that route.

Dont' sell out on the Ford 9-inch. I think it was available all the way up to around 1992. There is HUGE aftermarket support for them and they are easier to service than a modern 8.8-inch rear which has an integral carrier and has to be serviced in the axle housing. The Ford 9 has a drop out carrier that can be set up on a bench... unbolt the axles draw out the axles about 6 inches and the carrier is free.

My recommendation for the Ford 9 was based simply on swappability. Now if you can fabricate or have lots of money, then almost any axle can be made to work.

302 is a Windsor and a 351 can be either a Cleveland, a Windsor, or a Modified. 351W was never available in the Bump nor Dentsides. Clevelands weren't either but they are close to the 351M which became available in 1977 to replace the outgoing 360FE and 390FE.

A Crown Vic front subframe is a popular swap. Dentsides and Bumpsides are very very similar mechanically and dimensionally so do some homework by reviewing the tech thread compilation: https://www.ford-trucks.com/forums/1...l#post12560261

Scroll down to the links on lowering for some education and use that tech thread for reference cuz you've got some decisions to make before embarking on ownership on this series.

9 inch: 1957/80 misc FoMoCo Passenger Cars / 1957/83 F100 / 1966/86 Bronco / 1969/86 E100/150 / 1975/86 F150.

8.8" introduced in 1983 and 1983/86 could have either, as it depended on the applications.

Easiest is the same years as yours for 4x4, as in an F-100 (coil sprung front axle) or F-250 (leaf sprung front axle) frame from 67-72, as it is a matter of swapping bodies with some minor part differences. Next is the 73-79 4x4 swap, but you have to deal with the 2 inch difference in wheelbase for the bed. For 2wd if you don't like the Twin-I-Beam, you can do a Crown Victoria suspension conversion. Can you weld, fabricate parts, have a full equipped shop to do it in? Otherwise, you can you use most any other newer frame as other people have done.

4x4 a sd 99-01 f250 would be what I would try for a total swap but the frame on it is a good riding one not to much to tow with tho a ford 9 in is the way do a rear axle then a Dana 44 front is a good match for the 9 in. And lock the 9 in with a machincal locker is cool in high school and a good lift and 33s front rear disc brakes. The 97 seats are a great idea btw. A 205 tranfur case all very reliable stuff

Yep and 9 in is a good axle for that to as long as it is less then 400 hp or big slicks and high horsepower . I don't know a good frame for 2wd tho try a four link in the rear solves most axle warp

o ok...I mean I guess I could use a 2wd f250 then...I mean with todays market they r turning those into performance trucks, minded it looks horrible but mines is older. Do u think a diesel could fit under the hood? Just for the torque in 4 wheel mode? Or am I asking for trouble?

If it will fit and you have the money then it is the way to go a stock one can't hurt unless it is abused ( gunning it when the axle is bouncing and the like but stock new truck can't do that long) most will fit with small changes a 7.3 p.s. is the common choice besides a cummins (not a ford motor tho ) if you change the frame over use the dana60 and 10.5 axles that come with the f250 or thos are good axles if you want something different and stronger then the 44 and 9 in. both have parts and lockers you can get. you need a open diff to have a easy drop in of a locker
