I've pulled together the parts to replace the quad shocks with Monroe Gas-Magnums and the springs with Moog OEM, the existing parts look to be original.  I'm working to paint the frame (remove rust w/wire wheels, treat w/ospho, brush on Rustoleum Rusty Metal Primer and Rustoleum flat black top coat).  I would like to disassemble to where I can paint the frame components (i.e. the shock mounts, swing arms, etc) as the previous paint has all peeled and the frame is rusting.  Are there diagrams and torque specs available?  Related issue, when driving and coming to a stop I can feel a mild 'thud' in the left front as though something is sliding forward when coming to a stop, any likely suspects to look at while I break it down?  Anything else to get at while I'm in there?. I do have new Moog ball joints to replace the existing, though not sure I want to take that on.  Appreciate all help and advice.

Yo Whipsaw,

You can find the torques, diagrams, removal/installation etc. info in 96 Bronco-F-Series Workshop Manual (PARTIAL) by FORD via

http://www.diesel-da...stj/stjleft.htm

96 is same as most earlier years especially 92-96, except for:

92 through 95 uses the Electronic Engine Control, version Four (EEC-IV, aka On Board Diagnostics (OBD-I)) engine management computer.

96 uses the OBD-II (EEC-V) engine management computer;

4WABS (93-96);

RABS (87-92);

Air Bag (94-96);

3 ***** Automatic Locking Hubs (Built from May 95 through 96); Spark Plug Wire Routing & Firing Order (The firing order for 1987-1993 5.0Ls is 1-5-4-2-6-3-7-8. The firing order for 1994- 96 5.0Ls & all 5.8Ls is 1-3-7-2-6-5-4-8.);

R134a in 94-96;

2-piece Spindle Rolling Diaphragm Seal (RDS) used on 5/95 to 96 Broncos & F Series 1/2-ton 4WD;

Speed density EFI uses a Manifold Absolute Pressure Sensor (MAP), a Throttle Position Sensor (TPS), an Air Intake Temperature Sender (ACT) that gives the engine certain volumetric efficiencies over it's RPM range. Speed density EFI also uses what is called bank fire injection. 4 injectors are fired at one time on each side of the engine (only 2 wires for firing injectors from EEC-IV).

Mass Air Electronic Fuel Injection (EFI), aka Sequential Electronic Fuel Injection (SEFI) in 95 5.8 California models and in all 96s. Mass Air directly reads the mass of air (or number of molecules of air). By doing this, it can detect the changes in the volume of air, in addition to it's pressure & temperature. Mass air has one separate wire for each injector & fires them twice for every power stroke of the engine. This makes the injector timing more accurate & will help emissions along with power.

96 5.8 do not have the Air Injection (AIR), Secondary Air Injection; Pump (Smog Pump), Thermactor Air Bypass (TAB) & Thermactor Air Diverter (TAD) Solenoids; Diverter, Check & Bypass Valves, Cross-Over Tube, etc. But 96 5.0 does have the system.

Only 95 5.8L California models & all 96 have the Differential Pressure Feedback (DPFE) Sensor instead of EGR Valve Position (EVP) Sensor.

The 96, Vapor Management Valve (VMV) replaces the canister purge valve (CanP valve) used in EEC IV. But the 96 manual still shows CanP valve probably because it was a late addition to the 96 production line.

The Speed Control Deactivation Switch (SCDS) in a 93 Bronco is located on the driver side frame rail, but in 94 through 96 it is on the master cylinder.

Still researching other differences.

See Specifications in each section for mote torques.

Section 00-03: has Maintenance and Lubrication

Ford tech writers got dizzy and placed lubrication info in the component sections and here.

THE mild 'thud' may be a balll joint; see Ball Joint Inspection

Refer to Ball Joints, Front Suspension Upper Arm and Lower, Twin I-Beam Front Axle Equipped with Joints, under Component Tests in the Diagnosis and Testing portion of this section.

Refer to Section 04-01A for service to ball joint assembly on 4x2 vehicles. For 4x4 vehicles, refer to Section 05-03A or Section 05-03B.



Ball Joint, Lower, Inspection

Thanks!  The Coil Spring Insulators are probably a good call, the ones in there are likely original and at best tired.  I've been checking out some videos on the ball joint replacement, pretty much have to take the whole side of the front end down to parade rest and build it back up again to put them in.  The video below is pretty good, though if I were this guy, I would have hosed all the mud out the vehicle before starting out.


Mine isn't that dirty, but rust is an issue.  Have been wire brushing and spraying with PB blaster for a few weeks now as I've been painting the frame.  Will need to gather a few more items (bushings, the insulators, a ball joint press, maybe bearings?  ****, U-joints for the axle even... with the work involved to get to the ball joints, might as well).  Its going to be a little while longer before I get to this.

Don't forget to post photos of anything you find to be causing the issue.
