7-5/8 or 8.5" ring gear?
#1
so im in need of a axle shaft for my 99 jimmy with a 2005 GU6 G80 rearend, anyone know what size the ring gear would be on it? do the 8.5s only come on ZR2 models?
a friend sent me this link

i didnt take a tape measure to my cover but it does have the pointed ears on the bottom of the housing just like GMs 7.5 and 7.625 rear ends
my rear end
safe to say its the 7-5/8ths?

You have the 8.5 ring gear in that axle,I believe as that rear cover shot is identical to my GU6 without the limited slip! I have actually never seen a Blazer/Jimmy w/o the 8.5 gear! Ever! Just my input-step66

There are FAR more 7.625" rear s-series trucks than 8.5". The 8.5" was only offered in the ZR2 (all of them) and a few 5-spd 4wd 2dr models (but not all). Everything else got the 7.625" rear.
step66, it is likely that you have only seen Blazer's with the 7.625 and not the 8.5.

every junkyard in my city refuses to sell me a axle shaft, they only sell the entire housing complete but i found 1 just outside my city that im gonna grab tomorrow afterwork! got a 2hr round trip to get this stupid thing lol

If that's the case in the rear is it safe for me to assume the front is the same?

Hey swartlkk! You may be right! Just my experience with a 96 & 97 with the tow package and a GU6 has always been 8.5 ring! At least in the units I have owned. Sorry if I spoke out of line...step66

This is interesting as I spent some time in a salvage yard in DE yesterday-virtually all GU6 tow axles there had the 8.5 ring! Why do authorities make statements about the 7.625
when it doesn't seem to be true? Every Jimmy I have ever owned with the tow package had the 8.5! My experience only open to suggestions!

you will need about 2 quarts of oil to fill the rear dif... I filled mine by the book with 1 quart drove around for awhile and found weeks later it was too low. I needed just shy of a 2nd bottle.
