Hello everybody, I have a 1968 f100 that my father put a three-quarter ton rear end on the back of for work purposes. I now I'm trying to match the front end to the back and by adding a 1977 F 250 twin I beam suspension on the front of it. The mechanics that are doing it are having a problem getting everything to line up. My question to you is it a direct bolt up or what modifications do I need to do to make it work. Currently they have the I beams mounted upside down and I believe backwards because they could not get the steering arm to go through chassis member that connect from the front suspension to the under engine crossmember. This is obviously causing a camber issue that cannot be fixed by bending the I beams. I need to flip over the I beams and swap sides and that's where they're having the issue. They're saying it can't be done but I was told it was a direct swap

 

I can't believe they would do that and think it could work. Are they using the F250 radius arms? You would need the whole assembly from the F250 and probably the pitman arm too.

 

So the only things that I took for the install were the I beams and the spindles. I had them by all the calipers rotors etc. So I will need the parts you just mentioned they have this thing work?

 

Yup, looks like they are on upside down. Also the calipers should be on the cab side of the wheel, not the bumper side.

you should check out some of what Ultraranger has done.

 

That's one way to get some lift!

 

Your so-called "mechanics" are friggin' idiots. PERIOD.


Print out an exploded diagram and show them how the suspension is supposed to be installed.

 

Holy cow dude!!!
I don't even know what to say. Even if your not a ford guy, even my 17 year old will tell you where the calipers are supposed to be located.

 

Those mechanics must have a family tree that goes straight up.
The right side spindle will have a 3105 stamped on it. Left side 3106.
The right side I-beam will have a 3006 marked on it. Left side 3007.

 

I've never dealt with an F250 or F350 front suspension but, if you're going to swap Dentside front discs onto a Bumpside, I always say it's far better to swap the ENTIRE front suspension; Spindles, I-Beams AND the Radius Arms to eliminate mis-match problems such as this from happening.

I don't know about in the case of an F250/F350 but on an F100/F150 Dentside disc swap onto a Bumpside F100, you need to change out the hard line-to-flexible caliper hose frame brackets. Otherwise, the caliper hoses will be in a strain.

 

I wouldn't be taking my truck back to those guys haha. This takes the cake for the twin I beam disc brake swap epic fails!!! Is the donor truck you got the suspension from still around? Go there and get the rest of the parts if you can to make things all line up. Did you use the F250 coils? You can also get the proportioning valve, brake hose brackets and master Cyl as well. Can you get a picture showing the trucks stance as it sits with the current setup?

 

I wouldn't suggest going back and getting the MC but I would agree on getting the rest of the suspension components.

The MC on the donor truck will be of unknown condition. Get a new MC, not rebuilt and especially don't use a MC off of a wrecking yard vehicle. Best case is the junker MC will likely fail soon afterwards. Worst case is it will fail at the worst possible moment and damage to the truck and bodily harm may be the result of the outcome. --a brand new MC is about $50 bucks. Not worth the potential risk.

 

I guess not all garages are equal. I am now going to go to my local jy and find my missing peices. I wish this went easier, this thing looks great.

 

Rides a little high in the front and drives like a bronco (horse). The camber is currently stanced like the back wheels of a BMW.

 

I have a VERY hard time taking wrecking yard items and bolting them onto my truck, as-is. I always break the components down, clean and paint them and install the new consumable parts before installing the components on my truck. They might get dirty later on but they won't be dirty when I install them.

My truck is no show truck by any stretch and lots of things need attention on it but everything I add that's clean steadily reduces the areas of it that aren't.

Truly a thing of beauty. I don't have the budget or the time right now. Heck right now I just be happy to be able to drive my truck. I guess I could buy new parts. Probably cost me about a grand.
