Offroad Trailblazers and Envoys

Possible g80 or something else

G80, GU6, GT4, GT5, WTF? This section is for gearing and driveline stuff.

Hey follower offroaders I have a question... In my rpo codes in the glove box it does not say I have the g80, but when I break the rear loose both tires spin simlitaneously therefore acting like a locker... I tested this on an incline also covered in snow and ice and crawled right up with both wheels spinning.. So the question is, do I have the g80 or not.

If you didn't buy the truck new someone may have added the G80 after they bought it or they had the rear axle go out and just swapped it with one from a truck that had it.

Well I did not buy it new.. And I also took that into consideration that it could have been swapped in.

Roadie.. I was planning on it Saturday while at Barton's house gettin my skids.. If its not the g80 or any locker for that matter.. What could it be.. Without the g80 our truck only have 1 power wheel and it wouldn't let the other break free correct?

Put 1 tire on ice and keep the other on dry pavement... give it some gas and see what happens.

An open diff will let one tire break free and the other side will just sit there. Torque always takes the path of least resistance, like it's a fluid running out of a plumbing system. Except the input water (torque) flow is limited, so if you open a second spigot, pressure goes down everywhere.

With your trial of it, both tires had the same amount of traction, hence the possibility of both tires spinning.
Gotta get one tire airborne to see what happens. Or just open it.

Jack up one rear wheel. Attempt to drive truck forward. If truck falls off of jack, you have some sort of locking device. If the tire just spins flacidly, you don't.

I can think of other ways... But that sounds delicious.

Eat a bunch of bananas. Throw all of the peels in front of one tire. Watch as your truck slips and falls comically. Cue laugh track.

So why not drive over the big rock to the passenger side instead of squeezing through?
