Looking for someone to chim in with some helpful info on rear ends. If I were to jack my rear under the diff and spin one of the tires they turn in opposit directions. What does this tell me? Open/limited slip? Thanks, Steven

 

that tells you nothing, look in the glove box and read off the g codes on the build sticker

 

Well, the info isn't really for me my Tahoe has the G-80, but it does the same thing as discribed above. The info for a buddy of mine here at work. He has a 2005 Daytona.

 

I don't know codes for a daytona, but get the back tires wet. Mash gas. If one tire spins all day and the truck only creeps = open diff.

That sound about right to everyone?





One tire fire.
One wheel peel.
Peg leg
etc.....

 

He has the SRT 22's on it and it will pill the pass tire, but he said when he bought the truck it had the Dodge 20's on it and pilled both tires?

 

From a brake stand or when he has no traction on either wheel....like when its wet out.....

 

Dodges have a sticker on the axle on the passenger side... it should say something like "3.92 Trutrac" = 3.92 gears with posi.

you can pull the diff cover off and tell on a GM if you dont have the RPO codes in the glove box. .

my G-80 WOuldnt lock every time,, it took some persuasion and several attempts.

But i wouldnt just mash the gas with the G-80 it might go BOOM...

Hold the brakes and slowly get on the gas... if one tire spins... let off and try again.

 

I wouldn't do that with a G-80 either but the Dodge won't have one. If you use the brakes it equalizes the drag on both axles and will cause both to spin open diff or not.
