Changed Rear Differential Fluid

[chane]

It was pretty easy w/the instructions in these forums and Mountaineer Tom's pictures and part #'s.  I even decided to paint the cover dark blue to match the truck before I reinstalled it.  The hardest part was getting off the old gasket.  Had to use a little brake cleaner and pocket knife action to get it good and clean.  I took 2 quarts and one squirt out of the third bottle of 75-90w mobil1.  The allen wrench tip really helped.  I torqued everything to ~25lbs.  Is that right?

Just thought I would post something in here.  GM-TC has been dead the last couple of weeks..

I used 2 quarts and i estimated about .25-.3 of the other quart

I also found removing the old gasket to be a &*#$%^#

Did you use any gasket sealant?  Just curious

[chane]

No sealent, just a new GM 10 hole gasket.  I torgued them between 25-30lbs.  Probably closer to 25lbs because I didn't want to overtighten them..

Thanks for the reference chane.  Post a pic of your painted cover when you get one.

I used a small amount of gasket sealant.  No leaks so far.

I also used Toms advice on the allen wrench.......worked like a charm. I used some hi-temp sealent on my gasket, I figured since the old one had to be scraped off that it must have had some from the factory.

BTW Chane did you have any shavings on the magnet?

[chane]

Mine looked almost exactly like Mountaineer Tom's.

Ryan,

Do you know that guy in the link you posted?  If so, do you know if he makes those under seat storage box by hand?  Wonder if he could make one that covers the passenger side floor and the hump only?  Also, do you know if he painted it, or is that a carpet type covering?

I've been thinking about building my own type of storage box with a lockable lid, but have never got around to starting it.

TOM

yes i know the guy.  

He made one and has the drawings i think he was trying to get a patent.  Dont know much detail about it though.  

Let me know if you want his email ok

What did you end up putting back in your rear end?

[RyanbabZ71]

I'm just curious if anyone knows where I could get some lube for less than ? a quart.  Also, where did you purchase your new gasket.

[RyanbabZ71]

you can use mobil 1 75W-90 synthetic but if you ever have any trouble there could be a possibility of gm not covering it.

I bought the gasket at the chevy dealer for like ? i think.

i dont have the p/n on hand

if its not posted before i get home tonight ill post then

Part # 26066456

I think it was ? +tax @ my dealer.

[chevy4x4trucks]

just one more question.  I've heard that if you have a limited slip differentail you are supposed to use some type of cutting fluid.  Do you know anything about this?
