crawlinss Posted September 8, 2018 Report Share Posted September 8, 2018 so my rear end has a ton of slop in the pinion and unfortunately we have to rebuild the thing. i dont have 1600 bones laying around to replace the axle, and thats what theyre going for around here. question is as follows 2003 silv ss, g80, 4.10's. what SIZE RING GEAR IS IN THE AXLE?! i cant find any other way to narrow it down without measuring. from my searches the 10 bolt can have either a 9.5" or there is a smaller one too?? wtf? any help appreciated.

someotherguy Posted September 9, 2018 Report Share Posted September 9, 2018 The 10 bolt used in your truck is an 8.6" ring gear. The 9.5" is in the 14 bolt used on RWD 2005-2007 SS. Richard Quote Link to comment Share on other sites More sharing options...
stickler88 Posted November 3, 2018 Report Share Posted November 3, 2018 like someotherguy said, if you have AWD you have 8.6 ring gear which goes in a 10 bolt rear end. And most definitely 4.10 gears. Quote Link to comment Share on other sites More sharing options...
