If you tuned in last month, the first thing that might come to mind when you spotted the '56 F-100 frame pictured in this story is that's the rolling chassis we used in the November '08 issue of CCT to illustrate how to correct a potentially dangerous mistake made setting up four-wheel disc brakes. For those of you that didn't read the story, when we bought our complete used chassis for $800, it came outfitted with a stock '56 Ford single master- cylinder tethered to four-wheel disc brakes, and not a safe situation at all. To correct the problem we installed a dual-master cylinder setup complete with special mounting brackets from Classic Performance Products.
This time around we are dealing with something that's not nearly as dangerous, but it takes such a minor monetary investment to correct that it just doesn't make any sense not to. The Volare frontend graft that instantly gave our '56 chassis power steering, and disc brakes also eliminated the stock front coil springs, and should provide us with a cushy torsion bar ride. Cush that is, if it has been properly set-up. One of the most common fallacies about the Volare frontend is the torsion bar is adjustable enough to substantially lower the truck (ride height). It's true the Volare frontend can be lowered this way, but unfortunately the ride quality goes right into the dumper because now the truck is relying on the rubber bump-stops to act as springs instead of the detensioned torsion bar. Add this to a truck running a Volare frontend equipped with the smaller diameter torsion bar found on some Chrysler applications, and it's a guarantee there will hardly any suspension at all (does bounce like a baby buggy mean anything?).
It's true, while these days hardly anyone seeks to install a frontend as invasive as a Volare under their classic truck, there has to be thousands of old trucks that are still running around with one. If you happen to be one of those folks, and the Volare IFS never lived up to your expectations, we're pretty sure we've found the perfect solution.
We contacted our friends at Fatman Fabrications in Mint Hill, North Carolina, and ordered up a pair of their Volare 2-inch drop-spindles. In true Fatman form, the spindles don't require additional specially fabricated parts in order to be installed. With a little bit of massaging (covered in the captioned photos below), the stock Volare disc brake mounts and steering-arms bolt right up. After the Fatman Volare 2-inch drop-spindles have been installed the Volare torsion-bar is returned to a position where it can function as a proper means to dampen the bumps. Minor adjustments to the torsion-bar can be made to raise or lower the truck to make it sit level.
Oh, and in case some folks might be wondering where all of this going, the series that started in the November '08 issue will continue in CCT until we have built a $20,000 truck for around $10,000. It won't be like on Monster Garage where a gaseous bass voice comes out of nowhere and declares "freebie." Nope, we're going to stick to it; if we go over on the engine and transmission, and then need more coin for the body parts, we'll scale back and explain how we did it. The premise for our project was born when we picked up the '56 F-100 chassis that was setup back in 1987 and then discarded in 2007 when the '56 Big-Window's owner decided he would much rather have a brand-new Total Cost Involved rolling chassis under his truck (who wouldn't?). The next step fell into place when our friends at Sonoma County Street Rodz in Petaluma, California called and told us about a '53 F-100 in Novato, California for $500.00. Two days couldn't have passed when Jeff and Steven Costa rolled up with the '53 Ford in the back of Sonoma County's enclosed trailer. The trick to pulling the whole thing off will be in knowing where to draw the line. Since our donor '56 chassis was already set-up for a small-block Chevy, and we had already spent $2,990 for a Year One PowerCrate 350, the decision to stick with a small-block was easy to make (Editor's note: I know you Ford guys are booing like crazy, so here's to tell you we have a Y-block powered '55 Ford waiting in the wings after the '53 is completed). For a bulletproof tranny to handle the Year One motor's 412 horses backed with a dyno sheet, we are running a Gearstar Level 2 200-R4. In keeping with our tight budget, the Gearstar 200-R4 is known as the Street Rodder Road Tour package, and sells for $1,795 complete with torque converter, and all the goodies necessary to hook it up, including a Hayden cooler.

It can't be overstressed how...

It can't be overstressed how much easier disassembly work goes when the first step is to use a good penetrating oil such as Royal Purple Maxifilm. In addition this will help to ensure a minimum amount of damage will occur to the parts.

With the penetrating oil doing...

With the penetrating oil doing its thing, we used a flare-nut wrench to undo the brake fittings without rounding off the flats. Using a common open-end wrench is a good way to round flats off, and necessitate using Vise-Grips.

After the brake lines were...

After the brake lines were disconnected, we immediately capped off the ends with plastic pipe-plugs to eliminate brake fluid leakage (it's caustic) and eliminate the possibility of dirt entering the brake hydraulic system.

Removing the stock spindles...

Removing the stock spindles began by removing the caliper retaining bolt on top of the brake caliper, and then sliding the brake caliper sideways (left or right) from its mount. Do not suspend brake calipers from the brake flex-hose as it can damage the flex-hose.

With the brake caliper completely...

With the brake caliper completely removed, the next step was to remove the hub dust caps, then the cotter key, and then back the hub nut off counterclockwise. Once the hub nut was removed from the spindle, the brake rotor came off an assembly with the wheel bearings inside.

Once the disc brakes were...

Once the disc brakes were removed and the spindles stripped bare, the next step was to completely back the tension off the torsion bar (counter-clockwise) by accessing these bolts on the underside of the frontend (directly underneath this view).

It was necessary to disconnect...

It was necessary to disconnect the upper and lower ball joints to detach the spindles from the upper and lower control-arms. A pair of dikes was used to extract the cotter pins.

The upper ball joint requires...

The upper ball joint requires a 7/8-inch box wrench, and the lower a 15/16. We pre-soaked with Royal Purple Maxifilm and then turned both counter-clockwise.

We made our own ball joint...

We made our own ball joint separator with a 1/2-20x4-inch bolt threaded into 1/2-20x1-inch hexagonal connector. First the ball joint separator was placed in between both ball joint studs, tightened (expanded) enough to place a fair load, and then the lower ball joint was smacked hard with a 2-pound ball-peen hammer (see photo 10).

Next the upper ball joint...

Next the upper ball joint was separated in the same manner, and then the stock spindle was completely removed from the upper and lower control-arms.

Although our Volare IFS has...

Although our Volare IFS has very low mileage, it is 20 years old. The ball joints are in perfect condition, but the ball joint gaiters (rubber boots) are rotted junk. Unfortunately exact replacement boots are not sold separate, but we did discover a good solution.

But first we had to clean...

But first we had to clean away all of the road grime, and old grease with a rag. Then we lubed the uncovered ball joint with a grease gun to make sure the zerk fitting fed chassis lube thoroughly.

We looked to the folks at...

We looked to the folks at CPP (Classic Performance Products) for an answer to our worn-out boot problem. In this case a urethane boot from Energy Suspension was pulled from CPP's shelves to fit the bill. CPP also has their own line of general purpose rubber boots.

Fatman Fabrications includes...

Fatman Fabrications includes special bolts to attach the stock Volare steering-arms to the Fatman Volare spindles. We used high strength red Loctite on the two bolts to diminish the odds of a steering failure.

A 1/2-inch drive air impact-wrench made double-sure.

The use of a hydraulic floor...

The use of a hydraulic floor jack to compress the torsion bar enough to collapse the upper and lower control arms to meet the Fatman Volare spindles was instrumental to an easy installation.

With enough ball joint threads...

With enough ball joint threads poking through the Fatman spindles, we were able to run the retaining nuts down by hand.

Next we finished tightening...

Next we finished tightening the retaining nuts down with a box-end wrench, and then used a scratch awl to line up the holes for the cotter pins (keys) to be pushed in.

We knew the hole was properly aligned when the cotter key easily pushed in and appeared like this.

The last step was to stake the cotter key so that it appeared like this.

There are two slight modifications that need to be done. In order to utilize the stock Volare disc brake caliper mount with the Fatman Volare spindles, the raised circular bump on the casting has to be ground down to appear flat like this.

Then there are two flat SAE washers Fatman includes with the Volare drop-spindles that need to be placed (shimmed) between the Fatman spindle and the stock Volare caliper mount.

This is a before view of the stock Volare spindle. Notice the gap between the upper control-arm and the brake rotor.

Now look at the gap on this...

Now look at the gap on this after shot with Fatman Fabrications Volare 2-inch drop-spindle in place. It's a big difference, and it means all the difference in the world when it comes to making a Volare frontend have good ride quality on a classic truck.
