Looks like the pos diff on my 01 Sierra is now working. All of a sudden it stoped working back on March of 03 and now all by itself it started spinning both wheels again. I hope it stay working for a long while. I don't think I will ever get an Auburn ever again. I have had my Eaton posi in my 02 Sierra for over year now it works flawless.
This was done by my 4.8 ext cab with 3.73:1 Auburn posi with the stock 255/70/16 tires.

 

LOL damn man that looks far away!

 

Lol, i think your 4.8 has more power than mine.

When i was visiting Texas, many years ago, i saw plenty of long straight two lane blacktop. Glad somebody's puttin' it to use.

 

That is a mighty fine trailer house on the right hand side. Is it yours?

I think his 4.8 has more power than my 5.3

 

I wished it was mine. I would turn around and sell it on my sister's mobile home lot. She is the owner of Edinburg Mobile Homes. This would pay for the Radix I have been wanting for the longest time.

Its really easy to spin your tires on this frontage road. I choose this street only for picture purposes. On most streets my 4.8 will only scratch the tires.
