No 4x4 traction in 4 inches of snow??

[sdeeter19555]

Next stupid question, are you sure the front wheels were spinning? I could see issues if the actuator wasn't engaging the front axle...

 

I find it hard to believe that with a decent tire and the G80 you couldn't get out of a snow-covered driveway in 2wd, let alone 4wd...not that the GY SR-A is a great tire, but it should be decent if it had any treadlife. I seriously doubt changing from the G80 to any other locking differential is going to solve your problem...if the G80 operates correctly, it more/less locks the differential by clamping down on the LSD clutch packs.

 

TPMS on a HD truck is just another gadget (sort of like OnStar or a GPS: its there, but not necessary)...I air up/down so often that it made it confused, the reason I had them drop the pressure that trips the warning message. I did not buy my truck for it...

I dont understand how this g80 is supposed to be so great... Mine Never spins both tires,,, One in a blue moon if the pedal is smashed to the floor and i yank the wheel one way or the other in rain..it will break loose. Otherwise its 1 wheel drive!

I cant wait to get the posi unit in..

Mine works, every time.

[yukon25008.1]

Maybe the little rears in the 1/2 tons are different,

Mine works great in the winter. It never engages if there is no snow or ice tho . You would have to be driving on some pertty slipery roads for it to engage not in the winter.

[yukon25008.1]

Ok but wouldnt you want it to engage in the snow?? So theres power to both rear wheels vs just one tire turning in the snow andbeing stuck,

i wrote that funny I high lighted NO . It only seems to work in the winter basicaly.

So, with my Duramax 3500, I still don't fully understand the Traction Control. How does it work IN CONJUNCTION with the G80 locker?

 

Originally I thought that Traction Control was a "computer" operation - where it detects a spinning wheel, and then brakes it slightly.

 

But under 20 MPH wouldn't the Traction Control and G80 be working against each other? or rather "competing" with each other?

 

By the way, coming home yesterday on the freeway, with a light rain, wet roads, traveling about 60 mph, I goosed it a little to change lanes. And the rear end broke loose from the pavement. The truck slide sideways a little bit until I let off the gas.

 

Naturally, Traction Control was in the normal ON position.

Before buying new tires I'd try the next storm with traction control off. The all season tires suck but not that much. Traction control sucks and just pulls throttle when wheel spin is detected and you go nowhere.

I always turn off traction control when it snows. I have been stuck in a flat parking lot with traction control as it applies the brakes as soon as a wheel spins

[j-ten-ner]

But what is the traction control for when I have to turn it off anyway in order to get the truck out of the snow or mud?

 

so long

My G80 locks early and hard. Sometimes with a loud bang! I don't have traction control or stability control so with the torque of the Dmax you need to be ready or she gets a little tail happy!

Same here...if you're spinning slowly, you can actually hear it engage...mine does a "tick-tick-tick" thing before it goes clunk and it starts to move.

If you can break the rear loose this easy, then you need tires...end of story.

 

With good tires and sitting right about 450HP/800TQ in the last truck that had LSD, 6spd manual, and 4.10s; I had to work to break the tires loose on wet roads at any speed. However the junk BFG rugged trails it came with, I could haze them on dry pavement at 65mph in 6th, just getting into it.

Yeah ok, haze them at 65mph what BS.
