Georgia Flash Posted May 20, 2002 Share Posted May 20, 2002 Hey does anybody have any links that would help me identify the rear axle in a 76 Chevy Camaro? I would also like to know what axle ratio my 75 Z has. Any help would be appreciated. Ok afer a brief search I think I found my answer kind of, the axle code I have is "PU G61 391" Now the PU stands for "locking 2.73:1" the G stands for "Detroit Gear and Axel" but I am stumped on what the other numbers mean. Is this a posi traction rear end or not? Quote Link to comment Share on other sites More sharing options...
Mike C Posted May 20, 2002 Share Posted May 20, 2002 "locking" means it is a posi. In my experience, the numbers are not really accurate. Actually I am sure they are perfectly accurate, but the "decoding" is questionable. Only one way to know for sure, pull the cover. Ring gear will have number of teeth on it and pinion stamped on side. Look for numbers like 40 13 or 39 14 or similar in addition to part #. If it is locking it will have an "S" shaped spring between the side gears. On second though, if it is a posi, jack it up and rotate one of the tires forward, if the other tire also goes forward, it is a posi. If the other one goes backwars, it is a single track. Also if it is a posi, very easy to rotate the tires one revolution and count the number of times the driveshaft turns which will give you gear ratio.

Georgia Flash Posted May 20, 2002 Author Share Posted May 20, 2002 LOL thanks T Zee and Mike C, the next time I roll it down into the drive I will do the jack test and see what happens. If it is a posi I have a buyer alreaady lined up so cross your fingers on that one Quote Link to comment Share on other sites More sharing options...
