Oil leaking at pinion, 9 1/4

[dashshifter]

Greetings Dodgeboys, my 9 1/4 is starting to leak at the pinion seal. This rearend seal is new stuff for me. I've never changed this seal before. How many ft/#'s on the yoke nut? Anything special I should know for my first time. Thanks, Steve

Before anything happens get all the needed parts, cleaning material's and
new fluid from NAPA or the like. How is the flex brake line looking now ???

If you are in the same area, think about new U-Joints. It would be a
shame to repair the rear axle this month and be back there again several
months from now.

Ah, how did you end up with a 9 1/4 (corporate) axle under your truck? This axle didn't show up in trucks until '72. You should have either an 8 3/4" drop-out (1/2 ton), or a 9 3/4" Dana 60 (3/4 ton).
In either case look for loose pinion bearings; this is usually the cause of pinion seal wear and/or leakage.

My original 8 3/4 had an axle bearing failure. I got the 9 1/4 from the salvage yard. ( for free, a friend owned the yard ) It was in a '69 D-100. Apparently not the original one for the '69 either. At the time of my swap I put in new flex lines and u-joints.

You can't beat friends like that!
