transfer case

I have a 1992 ford bronco with a E4OD transmission which I'm replacing.I was wondering if there is some type of mainteance that I can do since I have the transfer case off before I reinstall it?

yo ROGMIT,

Replace TC seals, gaskets...and may as well do engine. rear main seal due to age issues.

and,
Transfer Case Fluid Level High & Low Transmission Fluid Level &/or Shift &/or Engagement Concerns TSB 97-12-13 for 87-96 Bronco & many others; "...transmission may have low fluid level and/or may have either a shift concern and/or an engagement concern. This may be caused by transmission fluid leaking from the transmission into the transfer case through the transfer case input seal. Replace the transfer case input seal..." read more Source: by Ford via thedieselstop.com

REMOVAL AND INSTALLATION
Rear Or Front Output Shaft Oil Seals 
Removal

1. Raise the vehicle on a hoist and position suitable safety stands under vehicle.

1. Remove the rear or front driveshaft from the transfer case output shaft yokes. Wire the driveshaft(s) out of the way.

1. Remove the output shaft yoke by removing the 30mm locknut, steel washer and rubber seal from the rear or front output shaft and remove the yokes.

1. Remove the oil seal from the front or rear output housing bore with Seal Remover T74P-77248-A and Impact Slide Hammer T50T-100-A.

 
Installation

1. Make sure the front or rear output shaft output housing bores and faces are free from nicks and burrs. Coat the oil seals with Premium Long-Life Grease XG-1-C or -K (ESA-M1C175- B) or automatic transmission fluid. Position the oil seal into the front or rear output housing bore. Position the oil seal into the front or rear output housing bore, making sure that the oil seal is not cocked in the bore. Drive the oil seal into the bore with Output Shaft Seal Installer T83T-7065-B and Drive Handle T80T-4000-W.

1. Install the yoke, rubber seal, steel washer and locknut on the front or rear output shaft. Tighten the locknut to 203-244 Nm (150-180 ft-lb) front; 162-203 Nm (120-150 ft-lb) rear.

1. Connect the front or rear driveshaft to the transfer case output shaft yokes. Tighten front driveshaft-to-transfer case yoke to 11-20 Nm (8-15 ft-lb), and Bronco rear circular ****** bolts to 28-33 Nm (20-28 ft-lb). NOTE: F-Series vehicles use a slip-yoke at the rear output of transfer case.
   
2. Remove safety stands and lower the vehicle from the hoist.

CLEANING AND INSPECTION
Transmission 
Cleaning

After the transmission has been disassembled, soak the parts except the bearings, in a cleaning solvent until all the old lubricant is dissolved or loosened. Brush or scrape all foreign matter from the parts. Be careful not to damage any of the parts with the scraper.

An excessive amount of foreign material usually results from a bearing failure, gear seizure, tooth breakage, extreme synchronizer wear, or clashing gears. In such cases, the input and output shaft bearings should be carefully inspected and replaced if necessary. Since countershaft bearings, output shaft pilot bearings, and reverse idler bearings are not so susceptible to damage from foreign material in the lubricant, they need not be replaced if they seem satisfactory.

Wipe the parts or blow compressed air on them until they are thoroughly dry.

To clean the bearings, rotate them in clean solvent until all lubricant is removed. Hold the bearing assembly to prevent it from rotating and dry it with compressed air.

When the bearings are dry, lubricate them thoroughly with transmission lubricant and cover them with a clean, lint-free cloth until ready for use.

 
Inspection

Inspect all transmission parts before reassembly to determine if they should be replaced.

The DieselHub site page for BorgWarner BW1356 Transfer Case maintenance ( http://www.dieselhub.com/maintenance/bw1356-fluid.html ) calls for MERCON synthetic ATF, 2 quarts, to fill the transfer case when changing the fluid.  As fluids have improved and changed, what is the recommended fluid for this application?

Yo Whipsaw,

Still Mercon ATF.

I' ve used it in our 96 Bronco since new.  Including many beach runs,  light off- roading, etc. No issues at all.
