Leaky Rear
No not me, my truck. It seems that it has decided to leak oil out of the oil seal in the rear axle housing. I looked through the shop manual and its part number seems to be 4676. Now is there any easy way to replace this. Can it be done with the rear in place? I was in Texas all week and now there is a nice puddle of 90wt gear oil under the truck. I had big plans for it this weekend and now it will have to sit.
Any info on this woill be appreciated.
I hope everyone has a good 3 day weekend.
Thanks

Sorry, did not see that thread until I posted mine, I was away all week.
My is a 52 the thread is on a 1960, is it the same? Is this a common part that might be available at NAPA or the like? I found it listed last night in the LMC catalog but it would be nice to get it locally.
Thanks again.

I won't have a chance to confirm til later, but as i recall the Dana axle in your '52 doesn't use a crush sleeve. So the procedure is the same, construction is a little different. You might PM 51Dueller, he sounds like he has actual training in these.

The pinion seal should be the same as all of the other Dana 44 axles. So you could ask for a front pinion seal for a 80-96 F-150 4x4. Be sure to have the old seal with you to compare to be sure.

that brings up my question.
We rebuilt my 8.8 rear last year, put a new crush collar and new seal, new axle shafts, new posi plates..
since then , it is leaking.. but not where you would expect..
the leak is at the flange nut. take off the driveshaft, and there is a couple tablespoons of oil there at the nut. Probably dripped 1/4 cup since last fall.
the diff side (seal side) of the flange is dry.
We did put in a different pinion gear to go to 3.55

well that loctite band would usually seal it diecent. wonder if theres supposed to be a seal between the back of the nut and the yoke.. like a oring... i bet no on eput any sealer on the yoke splines and it ran through the spines and behind the nut

I understand. I read and checked every install manual over a couple of years, watched a number of videos on gear replacement.. never had any mention of any sealer on the pinion splines..
I would never have expected this area to leak tho. (obviously)
Ah well, another fun job.. anyone want to bet the risk of just pulling the flange, and sealing without replacing the crush collar? All new gears.
(I have the bed off at the painters, so access is easy now)\
