I have a '54 3600 that needs to have this done. I am not very mechanical however my local mechanic is hesitant to perform this as he feels he would need to approach the pinion seal from inside and remove the differential gears. For those of you that have replaced this seal does the advice from "3B" up above in the thread hold true? Can it be done externally?

Any step-by-step advice would be great. I have the seal and will probably need a sleeve. any help would be appreciated.

Thank you
