Ford Bronco Solid Axle Steering
Solid Axle Steering
Steering geometry can get quite complicated. With a solid axle, you need to determine if you are going to run a steering box or hydraulic steering, steer from tierod arms or a custom high steer arm, tapered run rod ends vs. "Heim joints," and what your center to center lengths will be for your steering arms.
Steering Box vs. Full Hydraulic
With the proper geometry, a steering box with a draglink works just fine.
Hydraulic steering can be very expensive, cause a loss in road feel (depends on setup), can be prohibitively expensive, difficult to install, and dangerous if not set up properly. On the upside, hydraulic steering should eliminate any bumpstop and give you some very powerful one finger steering.
High Steer Arms vs. Tierod Arms
This depends on how much lift you have. High steer arms are better for high lift applications (greater than 6") and can be drilled to allow for just about any useful steering response (short length = fast steering; long length = slow, torquey and possibly even limited steering). Stock tierod arms can be used for steering by either stacking Heim joints or mounting a rod end to the tierod itself (stock Ford tierod or reamed and flipped Chevy one ton rod).
Heim vs. Tapered Rod Ends
Heims are generally stronger and can be stacked. Tapered rod ends are cheaper, work and may allow for greater articulation.
Center to Center Arm Lengths
If you are using stock Ford pitman arms (80-96), you will need a center to center of about 6.5" on your steering arm (high or tierod) or less to get full steering (on a Dana 60).
If you are using a Chevy steering knuckle (with longer than Ford steering arm), you will need a pitman arm at least 7" to get full steering (use a 7 3/8" Superduty arm 99 and up YC35-3590-AA).
Panhard Rod
A panhard rod should be set up at the same angle, as long as, and positioned as directly behind your draglink as possible to avoid bumpsteer.

According to the tech at Performance unlimited, the Stage 2 rod ends are the best around for 4x4ing. They are built much tighter, last longer, are built to drag mud and dirt off of the bearing and have 20° of misalignment, which is unheard of in a 3/4" by 3/4" rod end. They are not suitable for track bars, since track bars rotate too much and they make a different one that's made a little differently.

equivalent to an 8 inch long bolt being centered on the rod end, and
pulling on it as hard as you can and still barely move at all! An 8"lbs.
fit (Most other 'premium" rods ends) is the equivalent as being able to
move the ball with your finger tips

Example of maximum droop. Flat travel is approximately 19 inches and with twist it's over 20.
Superlift 6" coils, for a 79 Bronco limit the droop by about 7 or 8 inches.

Pitman Arm
Ford use a 36 spline 1 1/8" broached hole in their truck steering boxes.
Power steering arms for 1980-97 2WD and 4WD F-100 through F-350, Bronco, Bronco II and Rangers should be interchangeable.
The stock pitman arm is already "dropped" about an inch on mid-size vehicles such as the Ranger compared to the stock full-size arm.
The Superlift pitman arm has a 3" drop for full sizers and a 2" drop for mid-sizers.
The manual steering arm has a different item number than the power one. Difference?
78-79 Broncos and 76-79F150s have a different item number for their pitman arms than later model Fords.
An early bronco arm should fit on a 79 4x4 box. You need to move your mounting holes and drop in a worm gear from a 4x2 box
Early broncos also are angled differently than newer broncos since they run backwards.
Ford F250/F350 SD (pre March 99) share the same tuff country pitman as the 80-97 trucks.
Ford F250/F350 Superduty 99-04 have their own pitman arms. Superduty 7 3/8" (YC35-3590-AA)
National Tire caries Skyjacker's "extreme pitman drop arms" for 8" (9" for 79s and earlier) setups. Sound like it has 5.5" of drop, and it might be possible to flatten them out to at least 7" or more long - which is what you need for a cross over Ford to Chevy.

Custom Pitman Arms
If you are running a Chevy Dana 60, you will need a longer pitman arm if you want full turning ability and to mount your drag link with the tie rod.
http://bulletproofsteering.com/pitmanarms.html selection of "custom" Ford pitman arms - these are nice, but not suitable for a Chevy Dana60-ford interface. Howerver - if you can get one of their Extreme 4.5" drop pitmans prior to them bending it, that should work just fine - with a little downward bend for frame clearance.

Sky-manufacturing will make a custom ford pitman arm for $500. They know the two places in the US that have a broaching machines needed. This is a bit pricey, but if you design a longer arm, you can run your tie rod down to the stock steering arm on a Chevy style Dana 60. That means better clearance for the tie rod to frame and better clearance from your panhard rod since you will be able to put it at a greater angle. This may affect the mounting of your steering stabilizer.
A homemade pitman arm can be made by machining a broached part of the pitman arm into a donut, pressing into a custom machined arm and putting a really good weld on it.
Maybe take a flat Mustang pitman and bolt/weld on an extension http://www.srbymichael.com/manufacturers/peteandjakes/parts/pete_parts2.shtml

Chevy Tie Rod on Bronco
http://www.vintagebronco.com/coby/tierod/
If you keep the stock Chevy tie rod, you can flip it, taper the stabilizer hole and mount the draglink straight to that.
http://www.bc4x4.com/ryeguy/truck/comanche.asp#front_axle
1) 1.250 OD x 0.812 ID DOM for the tie rod (tap directly into 0.812" ID)
-any tube with the 0.812" ID will work
2) 1.5" .120 DOM for sleeving (optional)
3) Tie rod tube should be about 38"for stock early Bronco knuckles (39.5" for 76-77 disk knuckles) and drag link should be about 25" for high misalignment ends and 27" if using the tie
rod ends for the drag link). If using the F150 box and the high misalignment ends, then the drag link tube length should be 18.75".
4) 7/8" x 18 UNEF extra fine left and right hand taps

(541) 736-3743
Built for tapered Chevy 7/8 shank with CNC taper to be mounted on top
2" think in the back and then 7/8" thick at the end. The 7/8 tapered end is centerline of the steering arm. The end has a 10° taper so the distal end is level with the ground.
$135 each
There are a couple of choices.
The one with a two holes has them at 4 5/8" and 7" from the zerk fitting.
The intermediate one has a hole at 6" from the zerk fitting.
A custom pitman arm for a Ford can be made with a broaching machine for $500.

According to a post by Sean Stapley
Most trucks have approximately 4 turns lock to lock at the steering wheel.
The cylinder volume equals (piston radius squared x pi x stroke) - (shaft radius squared x pi x stroke).
Once you find the volume of your cylinder, divide that number (cubic inches) by the amount of revolutions of the steering wheel (lock to lock) for your displacement needed.
cylinder volume = ((2.5/2)"2 x (3.14159) x 8") - ((1.5/2)"2 x (3.14159) x 8")
displacement = cylinder volume/turns lock to lock

Hydraulics
The engineering science of liquid pressure and flow.
Hydrostatic power steering
Is a system where pressurized oil is transmitted to a steer cylinder (double acting) through a control valve which operates in response to the movement of the steering wheel. There is no mechanical connection ,such as a link , between steering shaft and the steering cylinder. They are only connected by hoses
Single-acting Cylinder (Ram) T
Has only one port for the flow of Hydraulic oil. It is used usually as a Lifting cyl as it expands with oil pressure , and contracts by force applied to the Piston, generally its own weight. It only has pressure to push the piston out, but will not push/pull it back in. This is not a ram that would be used in a steering system
Double-acting cylinder (Ram)
This type of cylinder is used for steering systems. There are two ports usually at both ends of the housing , both are used for the entrance and exit of hydraulic oil. Hydraulic pressure is used both to push the cyl open or to push the cyl closed
Valve
is a device which can control a few things
1- the pressure of fluids
2-The direction the fluid flows
3-The rate of the flow
Pressure
Is the force of the fluid. usually measured in psi (Pounds per square inch). If thought in terms of electricity this would be voltage
Volume
Is the amount of fluid flowing per unit time. Usually measured in GPM (gallons per minute) If thought in terms of electricity this would be amp's.
Stroke
The length of travel of a piston in a cyl, same idea as a engine
Bore
Is the diameter of the cylinder, same idea as an engine
Displacement
The volume of fluid displaced by one complete stroke or revolution. Same idea as an Engine.
Drift
Motion of a cylinder due to internal leakage past components in the hyd. system, usually due to blown seal/packings.
Accumulator
A container which stores fluid under pressure as a source of hyd power. It may be used as a shock absorber ( have not seen to many 4x4's use this. not sure why people don't though )
Cavitation
Air pockets in the oil circuit.

http://www.agrperformance.com/ - The AGR pump works great and is bolt on - but needs a larger reservoir to avoid cavitation. The stock filler tube can be easily cut in half so that a length (couple of inches) of PVC tubing can be epoxied (steel putty) on to lengthen it. It looks tacky, but works great at increasing fluid capacity, eliminating cavitation and even making it easier to fill (if you have AC).

Steering Geometry Basics
|
Caster is the fore or aft slope of the steering axis. The steering axis is a line drawn through the upper and lower ball joints of the knuckle. Positive caster is when the bottom of the steering axis line is in front of the tire's contact patch. Zero caster is when the steering axis is at 0o. Positive (shown) caster ensures good stability, helps maintain straight-ahead direction and promotes steering wheel self-centering. Too much positive caster causes hard steering, excessive road shock and shimmy.
|
|
Camber is the inward or outward tilt of the front tires as viewed from the front. Inward tilt is negative, outward tilt is positive. Camber is used to distribute load across the entire tread. Improper camber makes the tire wear on one edge, and causes the vehicle to pull to the side that has the most positive camber.
|
|
Toe is the side-to-side difference in distance
between the front and rear of the front tires. If the distance is
closer at the front, it's called toe-in. If the difference is
closer at the rear, it's called toe-out.
