If the pinion appears good as Wes mentioned, then changing the seal is not too big a deal. First thing after pulling the driveshaft is to scribe a line on the pinion and pinion nut so you know where to torque it back to. You're supposed to use a new nut.

Before you remove the nut with an impact gun, use a beam torque wrench or one like below to measure the rotational force in inch/pounds.

When you torque down the nut after installing the new seal and line up the scribe marks, you want to use the torque wrench again and make sure the number is 3-5 inch/pounds more or else you'll have to take it apart.

Bought a new AAM one and still need to send it out for powder coating. Orange of course as it's a pumpkin!
I appreciate the help, looks like I'm not prepared to tackle this job just yet. I do have a seal puller but I'll run out to the auto parts store to see if they have an install tool and torque wrench to rent as well as buy a new nut. I had no idea it was a one time use type deal. I certainly don't want to have to do this again if so, it's going to my mechanic.

Thanks again it is much appreciated

We used to only have Pearson and propel here, but for a while now, 76 has there own(they used to carry one of the other brands) and that's the most abundant here so that's mostly what I use.

That explains it. Out of those, I've only heard of 76 and there aren't any within hundreds of miles of me with E85. We have their sister stations, Conoco and Phillips 66, but no E85. I get my "E65" from RaceTrac.

Looks like this will get dragged into next weekend.
In the meantime, I went under to clean up all the gunk on the rear cover, figured it would make it easier to access the bolts and I noticed when I was using my metal bristle brush to get the gunk off that the bolts were moving.
Long story short, 4 bolts were finger loose.
Tightened them down until next weekend when they will be replaced with new.

Yeah, so Pearson and propel don't have their own stations here, they use other stations to sell their product.
So before 76 had their own, any 76 used to carry one of those two brands at their pumps and it would say everywhere that it wasn't a 76 product, shell and Arco are some of the other stations around me that still carry their products at the pump. Propel also does biodiesel I believe.

Here's the 76 station that had propel pumps at I used to use with my Subaru.
Just checked propel's website and they only have fuel in California. A little bit Northern mostly in LA and a couple in San Diego is pretty much it though.

Looks like shell and Chevron are the ones carrying Pearson for the most part, Pearson has a ton of stations these days I looks like.

We have a couple of E85 providers around Denver, one being Alta Convenience that handles Conoco products. But the E85 there is clearly marked as "not a Conoco product." The there's the K-U-M & Go (LOL) that doesn't differentiate; not sure who provides their fuels.

Yeah, all these places definitely specify it's not their product as well. But 76 I noticed a bit ago no longer has that on their pumps or at least certain locations don't that I've been to regularly and then I just looked up the other day and 76 apparently does their own e85 now.
