Last month I purchased something I maybe shouldn't have. I traded my 99 silverado w/200 plus mi. for a 2004,chevy 2500 lt crew cab 4x4 w/ quadsteer, (everything in it but kitchen sink)only 47k on it for $15000, the 4 whl steering amased me...made a little noise kinda like a posi-trac might do on pavement but didnt know so I got x-tended warranty. Took it in today to maybe change fluid in rearend diff. to calm the noise down..but I pull a camper and thought i needed the added steering, now mech at gm want to disassemble rear diff and find the noise, shavings,etc,,,,or whatever is making what ase cert mechanics say it shouldnt have been sold like that...it wasnt normal...dealership has informed me within hr. ok to drive in 2 wheel until monday when they take it and i get rental car.....hope this has a happy ending....quad steer is awesome

You'll probably need to add more information to your post, like what you purchased that you believe you shouldn't have and also why the GM tech believes he needs to do this work.

Probably not anything more serious than replacing some bearings. Not the end of the world. At least you'll know exactly what you have when he's done. Hopefully not TOO expensive to fix.

Just make sure they use the right diff. fluid -- the QuadraSteer trucks require a special fluid in the rear axle. As a matter of fact, if the previous owner put regular fluid in the rear that may be creating some of your noise problems.

+1 Its GM part#12378557 (And DO NOT add friction modifier to it)

Check the Quadrasteer Club site. Lots of tech tips. My quad made rear end noise after diff was rebuilt with 4:11 gears, wrong oil. GM special quad oil fixed'

 

 

might seem like a silly question, but what gears do you think came in mine? Seems the wrong oil is a frequent problem....still in shop, maybe mine will be back thurs...curious to hear what problem was.

Most quads came with 3.73 or 4.10. Should have build list in glove box. or ask dealer to look up vin build list. most info on quadrasteer club.com=quadrasteerclub.infopop.cc

Look in the glove box if you see GT5 that = 4.10's if you see GT4 = 3.73's. Unless quad steers codes are different.

it was limited slip clutches...gm replaced them, no big deal but even they say it was unusual for 'em to go out so early(50.000 miles)...not quadrasteer related

it is a gt-4(3.73)...is that lower or higher than 4.10's

LOWER GEAR= NUMERICALLY HIGHER

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
