Hi i could use some advise as ow to repair my leaking rear diff, its leaking where the prop joins so is it an easy repair??? would it be easier to replace the diff???

please help

if no movement on diff flange up/down etc remove flange prise out seal (frc8220) fill rear side with vaseline etc to hold garter spring in place ,tap seal in square and replace flange tighten nut tight job done,brg preload done with shims between brgs so you wont effect it
