My friend and I took some things too big for trash man to the dump. 99 times out of 100 I can back up a trailer like nobody’s business. But this time I almost backed into someone and had to try three times. Must have been the smell affecting me!

Should've had your buddy there guide you in.

And it was really windy, and snowing, and up hill!

Interesting, but I don't think we have any Marathon stations around Denver, so I'm wondering what refinery would supply either the gas or E85 product.

The only gas refinery in Colorado (Suncor - https://www.suncor.com/en-ca/what-we-do/refining/commerce-city-refinery) is just now starting to supply gas again after being shut down for about 3 months. Not sure if they produce E85, but maybe @TollKeeper would know.

Im pretty sure its either going to be Nustar, Sinclair, Magellon, or SunCor. My company supplies almost all the E100 product to them, and they dilute it to the E85.

I have a limited access to E100. But nothing I own is even remotely capable of E85.

Crawled under there and torqued all the bolts on the diff cover before I dropped 300 bucks on a fancy cover.
Glad I did, all of them turned quite a bit to get to 25 foot pounds (I know 30 is the spec, just seems excessive. Pretty sure I only hand tightened them last time I was in there changing the felpro gasket that split and leaked out for the lube locker gasket.

Unfortunately, noticed that opinion seal is also leaking... That's a lot more of a pain in the butt job. So we're just going to pretend we didn't see that for a while.
Now wondering if the Cadillac this axle came out of was in a front end collision or something, maybe pushed the drive shaft into the diff. Because when I checked the backlash when I got it, it was tighter than factory spec should have been and it's supposedly had between 50k and 100k miles IIRC, and now leaky seal after maybe 15k mi.

Good morning, does anyone know if there are replacement grommets for the under side of the stock air filter box?

Also, years ago I remember someone doing a write up for modifying the stock airbox and inner fender to allow more air to flow through? Does that sound familiar?

@iamdub did something like it but it may have been just to repair the seal and make it better.

The grommets reside in that plate that is missing them. $13 or so for a new one. Someone just posted this the other day.
