It is fairly easy to do. remove rear wheels and brake drums, remove the differential cover, rotate the diff to access the diff pin bolt and remove, remove pin, push axles inward and remove c clips, slide out axles and replace seals. reverse procedure

You might want to research Ford 4x4 Clubs or Bronco Clubs and things like Off-roading publications. Ford use to have performance displays at some Dealerships. There are some specialty shops which can shorten rear axles.and narrow rear ends. One thing to remember is that both the front and rear differentials need matching gear ratios. So whatever you do, think of pairs.
For That you use a C-clamp style ball joint press to remove the ball joint from the suspension arm-note the location of the receiver cup ! For installation of the ball-joint, use the same tool when pressing the ball joint into the suspension arm-again, note the location of the receiver cup.
Step by Step :
Raise and support the vehicle safely, with jackstands.
Remove the spindle and the ball joint assembly from the vehicle.
Remove the snapring from the ball joint. Using a ball joint removal tool, remove the ball joint from the spindle. Do not heat the ball joint or the axle to aid in removal.
Installation is the reverse of the removal procedure. Torque the ball joint stud nut to 85-110 ft. lbs. for 1983-89 Ranger and Bronco II.
leaking where? axle shafts? pinion seal? diff cover?
should inspect diff internals and bearings-may require overhaul not just
seal replacment. also check vent tube-if plugged will cause all seals to leak.
remove rear cover from rear differential. catch nasty smelling oil (gear lube) in drain pan. remove bolt on side of carrier to be able to pull pin out from so called spider gears. if you have limited slip you may hve to pull S spring out from between side gears. then push axles in and remove C clips fom end of axles. then pull axles out. installation is in reverse of removal. make sure that the C clips are well installed in the groves whe reinstalling axles, or they could fall out and axles will come out while driving. bad deal.if you have limited slip get a bottle of friction modifier from parts store to put in there with new gear lube . is a small bottle like 6 to 8 oz.kepps clutch packs from chatering on turns.
Wheel, brakes etc that are in way of pulling axle out have to come off. Drain rear end fluid, remove rear housing cover, remove bolt that holds pin in differential, remove differential pin, push in slightly on axle to remove "U" clip that holds shaft in, then slide shaft out. replace seal. Reverse procedure for re-install & fill with gear lube. If any questions, get back to us.
if it is the seal, you will have to remove the caliper and rotor, remove the differential cover and remove the bolt and pin inside the diff carrier housing. push in the axle and remove the axle clip and pull out the axle use a seal puller or prybar to remove seal reverse the steps to assemble
