Thank you for the help over the last month with my new 93 Bronco. I have had it just over a month and have done a lot with the plugs, wires, rotor and cap, tailgate issues, etc. I am ready to change all the fluids. Cannot find what exactly is the correct choice for everything. Haynes does not tell me anything, searching by VIN is no help, and I seldom trust the 18 year old at NAPA.

93 Bronco, 5.8L 351W

As I read more I assume it is a E40D Gear Box

Engine Oil - Last was 5W-20 that was put in

Automatic Transmission Fluid type? Changing the filter and pan gasket. It is leaking from the gasket.

Transfer Case Fluid?

Rear differential Fluid? No tag which could have been removed so is it limited slip or open dip? Gasket or RTV?

Power Steering Fluid? May have to change the pump out. Looks like it is leaking somewhere.

Not excited about the oil pan. The pan is leaking and maybe a bad pump. What I read is way to much for what I can do to get the pump and pan gasket changed.

After that it is on to check for a vacuum leak.

choices of brand of oil s to use are all ways up to personal preference. I use rotella 15w40 motor oil Castrol trans fluid, the transfer case uses trans mission fluid also. rear axel I would put in 75w140 again brand is up to personal preference, chances are that your bronco IS a limited slip differential, so be sure to add the friction modifier additive. the tag really only identifies the gear ratio and specs on the diff bearings, no real need for it in my opinion

Yo Treg,

Following by Ford for 96 Bronco;

96 Bronco-F-Series Workshop Manual (PARTIAL) by FORD via

http://www.diesel-dave.com/vehic/manual/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;

Mass Air Flow in 95 5.8 California models and in all 96s, other years used Manifold Absolute Pressure Sensor (MAP).

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.

The 96, Vapor Management Valve (VMV) replaces the canister purge valve (CanP valve) used in EEC IV.

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. Both have recalls.

Still researching other differences.

...

Fluids,

See Section 00-03: Maintenance and Lubrication

"Engine Oil Viscosity

Gasoline Engines (4.9L, 5.0L, 5.8L, 7.5L)

To choose the correct viscosity oil, temperatures in which the vehicle will be driven must be considered. The use of SAE 5W-30 oil is preferred in all climate conditions. The use of SAE 10W-30 is acceptable in moderate to hot climates.

Ford recommends using Motorcraft oil or an equivalent oil meeting Ford specification ESE-M2C153-E and certified by the American Petroleum Institute for gasoline engines.

Use only engine oils displaying the American Petroleum Institute certification mark on the front of the container."

Depending upon engines age, oil loss, pressure (btw, the oil pressure gauge uses just an on-off switch thzt opens at around 4.5 psi thus moving the needle to mid-range) etc. you may want to go with 10w 50 with a quart of Lucas oil stabilizer, as suggested by Seabronc.

To modify that circuit or to add a true sendor and/or gauge, see mmy site @ http://web.archive.org/web/20110704142136/http://www.broncolinks.com/index.php?index=949

"Put the transmission in neutral and jack up both tires."

miesk5 Note; chock both front tires FIRMLY. Best is to have your Bronco facing out in a garage or close to a solid brock wall or an Abrams M1A2 main battle tank.

"Turn one tire. If the other tire spins the opposite direction you have an open differential, and if it spins the same direction you have a posi or a locker..."

"Jack up one tire if you have an open diff, or both tires if you have a working posi or locking differential. Rotate the tire one full revolution for posis and lockers and 2 full revolutions for open diffs. Carefully count the number of full revolutions the driveshaft makes. This is your gear ratio. In other words, if the drive shaft turns 3 ¾ turns, you probably have a 3.73 gear ratio. Turning the tire for twice the number of full revolutions and dividing the drive shaft revolutions by two will give you a more accurate reading."

That 5w20 oil is way too thin for your truck, which is likely why you think you have a bad oil pump.   If your engine were fairly new, a *w30 oil could be used.   You would probably do better if it is a high mileage engine, with a *w40 oil, which is what I use.    The correct transmission fluid is stamped into your tranny dip stick.   Use the same in the transfer case.   Use the **w140 gear oil in the rear end and standard power steering fluid.

Just a couple things that I cannot find on your replies and cannot find it anywhere.

Torque specs for the  bolts in the oil pan, transmission pan, and the rear diff cover.

Also they make a rear diff cover gasket but should I just make one using RTV. Which one would be better.

Yo Treg,

#25. Install oil pan gasket and seal assembly. Install oil pan. Tighten oil pan bolts to specification. Tighten the four 5/16-18 x 1.12 oil pan bolts to 12-16 Nm (9-12 lb-ft) and the remaining 1/4-20 x .94 oil pan bolts to 10-14 Nm (89-124 lb-in).

See diagrams @ http://www.diesel-dave.com/vehic//stj/stj31b46.htm

Includes gasket/sealant locations

Other Engine Torque Specifications @ http://www.diesel-dave.com/vehic/manual/stj/stj31b50.htm

...

8.8 @ http://www.diesel-dave.com/vehic/manual/stj/stj52g10.htm

Excerpts; "...CAUTION: Make sure machined surfaces on both axle housing cover and carrier are clean and free of oil before installing the new silicone sealant. Inside of rear axle (4001) must be covered when cleaning the machined surface to prevent contamination.

Clean the gasket mating surface of the rear axle carrier casting and axle housing cover.

Apply a new continuous bead of Silicone Rubber D6AZ-19562-AA or -BA or equivalent meeting Ford specifications ESB-M4G92-A and ESE-M4G195-A to the new axle housing cover.

NOTE: Axle housing cover must be installed within 15 minutes of application of the silicone or new sealant must be applied. If time permits, allow one hour before filling with lubricant to make sure silicone sealant has properly cured.

See diagram.

Install axle housing cover and tighten bolts to 38-52 Nm (28-38 lb-ft). Tighten the cover bolts in a cross-wise pattern to maintain axle housing cover flatness.

Add lubricant through the filler hole until the lubricant level is 6.4-14.2mm (1/4 to 9/16 inch) below the bottom of the filler hole with the axle in the running position. Add 5.5 pints of Premium Rear Axle Lubricant XY-80W90-QL or -KL or equivalent meeting Ford specification WSP-M2C197-A, plus 4 ounces of Ford Friction Modifier (for Traction-Lok® axles) F3TZ-19B546-MA or equivalent meeting Ford specification WSP-M2C196-A. Install the filler plug and tighten to 20-40 Nm (15-30 lb-ft)..."

I haven't used a gasket in our 96 8.8 open.

Did the gear check once I got it lifted up. Axle rotated a little over 4 times. Limited slip chart you showed has a H3 4.11 and a H5 4.10 which would be close. Anyway to figure out which one of the two besides what I just did?

Thank you everyone. New transmission fluid, filter, and gasket did the trick. Runs like new! A couple things concerning the threads.

Rear differential - Not sure if is a Dana 44 or a 8.8. Gear ratio is 4.1. What was recommended above was 2.75 quarts. I put that in and that did not even come close to the fill hole. The truck is lifted so the top of it is tilted farther back so do I need to keep filling until it is 1/4 inch below the fill plug or leave it as it is?

Transfer Case - I assume it is a 1356 by everything I read above as it was the only one I see that was in that truck. One thread says it will take about 2 Q. Another thread says it will takes 4.1 Q more with a PTO. When I filled it up from the back fill plug it only took 1 1/2 Q. There is a large skid plate below it that I would need to take off to see if there is a fill plug on the front. Am I assuming this is a 1356 PTO and takes more fluid?

Yo Treg,

MF! I lost my reply. Freaking error meesage claimed I was not logged in. So here ot is again.

8.8 Cover Gasket Depiction

Information, History, ID, pics, etc.; "...8.8” rear has a ten bolt inspection plate on the back that’s about 10” from the center of the top bolt to the bottom bolt center. The 8.8” first saw service in the 79 Crown Vic. and in 1980 for the F100/150..."

Source: by Kenneth C 8.8 Information, History, ID, pics, etc. @ @ http://www.badshoeproductions.com/rear.html

See 9" & 10.25"; as well as Dana 44 in 80 through 96 Broncos.

That is correct amount if fluid. That must be a high lift; how much is it lifted?.

Wonder what the angle is?

overfilling or underfilling is not good.

Other members can offer opinions.

MEASURING AND CORRECTING ANGLE PROBLEMS @ https://www.drivelinesnw.com/part-trouble-shooting/vibration-analysis/angle-analysis/measuring-and-correcting-angle-problems/

Spec specifies that refill capacities are determined by filling the rear axle 1/4 inch to 9/16 inch below the bottom of the filler hole.

Yo,

I re--read your last reply and finally my brain realizes that your Bronco does not have a suspension lift.

I was thinking of adding this, but deleted it. Here it is anyway in case it does have a big lift, such as ovsr 4 inches total.

"Another thing to do if your axle has been clocked for steep pinion angles is to check for proper fluid levels in the diff housing, as you may have to overfill the housing to ensure that the pinion bearing is not starved for oil. However, be sure the added oil doesn’t lead to less-effective lubrication from foaming of the gear oil... Adjusting the rear pinion angle on a leaf-spring-equipped vehicle is as easy as adding some pinion-correction wedges under your leaf pack. Six degrees is about the most angle you want to run with a wedge. Beyond that, the spring perches should be cut off and re-welded to the correct angle. Coil-sprung vehicles can be more difficult to adjust because the control-arm mounts will sometimes have to be removed and rewelded, unless you are running eccentric bolts or have adjustable arms. It all depends on the vehicle and amount of angle needed..." more including pics @ http://www.fourwheeler.com/how-to/transmission-drivetrain/129-1207-drivelines-and-geometry-understanding-pinion-and-driveshaft-angle/

Use the link I posted previously to verify it is the 8.8.

Dana 60 pic installed in a 91

Source: by DcSkater602

But the Dana 60 does not have provions for the Vehicle Speed Sensor (VSS) NOR the internal tone ring. So no ability to provide a 72,900 to 86,900 pulses per mile signal via the 4WABS module to the Programmable Speedometer/Odometer Module (PSOM); PSOM converts this signal to 8,000 pulses per mile. That signal is sent out to the PCM and then to:

E4OD, if equipped;

speed control amplifier, if equipped;

and overhead consoles compass/outside temperature display module, if equipped,

See attached pic below.

Thank you Al. You have been very helpful and enough stuff to look through that will keep me busy for weeks. As you can see by my profile picture it is lifted a bunch and at least 4" if not more. Those are 35s on the rims. I will take the info from one of your links and find the angle.

Since my last reply I contacted the last owner and he found a bunch of paperwork dating back from 1999. The only thing I cannot find is when the lift was installed and he did not know. He has only had it since 2010 and only had some paperwork from owner #2. Not knowing anything about suspension and body lifts should not be an issue and I am pretty sure there is a 4" body lift at least

The next was all put on in 2003

Rear - 8.8 with a Yukon Gear & Axle Ring and Pinion Set YG F8.8-411 and Master Overhaul kit YK F 8.8-A

Front - Yukon Master Overhaul kit for Dana 44 IFS differential YK D44-IFS-L and YG D44R411R Ring and Pinion Gear set

It has Eaton Detroit Lockers 187C145A

ARB-RD06 Air Locker for the Dana 44 and ARB-RDCK 12V Air Compressor

Put on in 2011

Suspension has Sup 85280, Sup 85300, BDS 099270 Red Boots, and SK7 7290 Duel Stabilizer

I should be able to figure most things out now and thank you so much for your help. I will try to figure out as much as I can without troubling everyone on stuff I should just take some time to understand and look up.
