Pinion seal

[01cummins6]

I need help locating a pinion seal for my truck .it's a 2001 dodge ram 3500 2wd 6 speed with a Spicer yoke. I replaced it and is still leaking.

Have you cleaned out the axle vent? The axle vent being clogged is one of the main things I find that cause pinion seals to leak.

I checked it last night it's fine

Is the pinion scored? Did the tension spring come out of the new seal when it was installed? Is the pinion loose causing it to walk?

I didn't see anything scored and everything else is fine. But there was 4 different seals and I'm not sure it's the right one it fit but it is leaking around the yoke

This is what I've got. Sealed up perfectly. It should be the same as yours (Dana 80)

That's a pricey seal

Sure is. Doesn't leak though, and that's what matters.

You need to make sure the nut is torqued properly too.

So surprisingly, the stealership has that same seal for around $55.  I put one of those in because the Advance Auto didn't have it in stock..  Has been working great so far

I got my seal from Sadler power train local heavy duty axle and everything that has gears rebuilder. I believe it was about 20 some bucks, and it was an original Spicer seal. The nut on my axle M80 which is same pumpkin as standard 80 and 70 wheel bearings,I belive, I just marked it and put it back same place maybe 16th passed. There is no crash sleeve and I used 3/4 impact to take it off and put it on. Can't remember if there is a washer but make sure to put it back the way it came out or the nut will not be in same place, also I put a little bit of RTV under the washer.
