my uni F100 with 8 lugs,

[slickmainer]

the truck cab is an F100 per glovebox tag but the truck as 8 lugs. Thought they might be spacers, so I took a wheel off, and didn't find any spacers.

Is this an F250 looking front drum?

There is a pair of springs going around the outside of it...what is that? do I take that off then unscrew the screw on the face of the drum then knock the drum off?

Also found a crack in the shock tower...this just keeps getting better and better...

drum and spring around the top

SM,
I believe the spring is there to function in an effort to reduce vibration of the drum. I've seen them before. I'd just leave the springs be.
Go ahead and remove the screws to separate the drum from the hub.

Now the cracked shock tower,,,,,,,,that's a different issue! I'd bet some welding will be in your future!

As far as the 8-lug hubs on a F100, I'd say someone switched them from a F250 to your F100 sometime in the past 40+years!

yeah, i'll weld it or just find another one and bolt it on, thats what you get when you just look at photos and dont see or feel around it in person. oh well it's all fixable and I can just hop in my other one if I want to drive a slick

nothing wrong with the springits heavy duty. keeps the drums from expanding and cracking if they get hot
must be they hauled a camper or something
the f250 brakes are bigger
all you do is swap out the backing plates and drums the spindle and bearing are the same size.
find a 9" rear with 3.50 and some new u bolts and the rear is done easily too.

i can get you the ones from the frame i have been cutting up.
i have some nice low mile used shocks i will give you a great deal on too.

Brian, im ok with the 8 lugs, I just wanted to know what to search for when buying replacement brake parts ie. F100 or F250. So are you thinking behind the drum is normal F100 parts (shoe size and springs and stuff)

Let me take the wheel of the passenger side to look at that one and I'll get back to you for the shock tower.

[ICEMAN6166]

what i mean is that you can trade all of the f100 or 250 stuff on the same front axle but the drums and shoes are bigger on the 250. you need to order f250 shoes if you do a brake job.

[slickmainer]

ok thanks, i misread your prior post.

....I just wanted to know what to search for when buying replacement brake parts ie. F100 or F250. So are you thinking behind the drum is normal F100 parts (shoe size and springs and stuff)...

Gregg,

I suggest you don't assume - as the shoes may or may not be the same as F100 shoes....it may depend on what model year the F250 8-lug hubs, backing plates & drums came off of originally. Is your rear housing a 9" or a DANA 60?

I had a similar mystery with my '65 F250 when freshening the rear brake shoes. Come to find out the original '65 F250 DANA 60 rearend had been changed out and a '67 F250 DANA 60 had been installed by a previous owner. I first noticed that something was fishy when the rear brake shoes were a different size than what it should have been. I knew that originally a '65 F250 has 12-1/8" x 2" brake shoes on both front and back. But that a '67 Dana 60 originally was equipped with 12" x 2-1/2" brake shoes. My truck had the 2-1/2" wide shoes. Further investigation revealed that the carrier tag code did confirm it to be a '67 rearend.

Let this be another example why a person should keep a written record of what you're bolting onto your Slick if / when you are changing stuff away from original model year or aftermarket stuff....it will be very handy for your future reference.

f100 and f250 front shoes and drums are not the same size
the spindles and bearings are. so are the springs that hold the shoes on.

the d60 rear went to wider shoes in 67
no 9" rear takes f250 stuff, only the 60

[slickmainer]

im not sure, i think a 9"


I'll pull the rear tires tomorrow and slide under the rear with a scraper to see if i can find a tag for the year. maybe the rear has adapters from the 5lug??

[ICEMAN6166]

that is a 9"

[BarnieTrk]

HOLY ROUGHRIDERS, BATMAN!

What model year 9" rear housings came with a suspension like that??!!
6-leaf auxilliary spring packs on top of 8-leaf packs.... or were these packs custom done and likely added when they adapted the 8-lug pattern to the axles?

Was the rear fill plug also added or is that a clue as to what model year the 9" housing may have come out of?

[slickmainer]

I really wish I knew.
my guess is that the extras are aftermarket since there is one piece of rubber on the drivers side and two block of wood on the other.
It also had a second gas tank at some point because there is a hold in the side of the bed and exta fuel lines heading to the back and a switch on the panel just behind the driver

[Greg D]

Looks like stock F 250 HD springs to me - pack in my 64 250 looked just like it.
Those 250 leafs work great if you wanna lower it but not have it bottom out.
I pulled too many leafs from the set of 100 springs on my Uni - it could barely carry a 6 pack of beer in the bed.
I did the springs in the 64 exactly the same way - it has a decent amount of load capacity but a good stance.
Are those bolts all around the rear of the differential housing?
9" would only have those on the front around the carrier.

[slickmainer]

i'll check tomorrow. so much gunk on there, hard to tell what is what.

[BarnieTrk]

Gregg,
What do the upper / auxilliary leaf springs flex against? Is there a frame bumper mounted above the ends of the leafs or what?

As I recall, usually rears with auxilliary springs have the U-bolts going from top to bottom, with the nuts below the axle, rather than above the springs....yet this one isn't that way.....???

Greg D,
I see what you're seeing now, it does look like there may be a set of bolts around the rear of that pumpkin.....? It sure is round; much more round shaped than most DANA rears...it appears to be even rounder than a 9"... but maybe it's just the angle of the photo too...... ???

The springs around a brake drum are noise reducers that help eliminate harmonic noises. They are actually tuned and different makes and models can use a different number of coils for the same drum size based on application. Hawkrod

no $h!t !

did not notice those in the grime until you mentioned and i took another look

cant be a 9" then. does not look like a d 60 either.

cornbinders and dodges used d60s too.

i am stumped as to wtf that is

clean it off real good and look for a tag or some numbers

[oldtrucks]

That could be an Eaton rearend could have been swaped in from a GMC they were used back then.

[slickmainer]

looked at eaton rear ends on line and the bolts look really similar. especially the center fill, the 3 bolts on the bottom and the the two close together on the sides

this is an online image of an eaton ho52
