    Miss the hell out of my G80. The tiny 04 Colorado went all sorts of places my GMC Sierra doesn't. The GMC has open diffs which for the life of me I don't know why they would even make them for trucks. Plus just driving down the interstate hitting icy patches it kicked in was super smooth and no issues. Oh well

    I have noticed that in the winter (here in Finland) the locker does not work if the rear axle is cold. The fine centrifugal mechanism is too stiff to work. Sometimes it gives a ratcheting noise as the mechanism almost connects. When the differential is warm the locker is next to perfect. I have a -79 Blazer with Auburn front LS, so the truck is about as good off road as my -07 H3, sometimes better. Worst of my "fleet" is the Jeep GC ZJ with only rear limited slip, actually just "limited traction". BTW, that Eaton locker is called "the cuckoo clock locker" here because it looks like having a clockwork mechanism inside... :D

      My 98 Jeep Grand Cherokee had the limited slip as well, only thing it was good for was getting you sideways in slippery conditions, otherwise it was actually useless when traction was needed. I think the clutch pack was worn out in it for the most part anyways.

    The 10.5” “Gov-Lock” is the only of the Gov-lock series that doesn’t regularly explode. They are pretty great for normal vehicles.
    If you have big tires or go off-road, get a Detroit or selectable locker, you may blow a gov lock up still

      Have to disagree. Seen a few broken ones in stock trucks with 14 bolts. Including my latest truck within the warranty period. And that's without abuse, just heavy use. Stock tires. Very cumbersome when used in a real world situation. People don't often get stuck with one tire on dry pavement. These things have been outdated for 30 years. At least if you start with an open diff, you're only a couple hundred bucks away from a locker that actually works when you want it to.

    • @codymoncrief8478

      Likely candidate out of curiosity, is it the “Open/square” carrier Gov-lock or the first-generation 3-pinion Gov-Lock that has the conical enclosed carrier? I should have noted I meant the Conical-carrier gov-locks specifically (from the square-body era). While still present, their failures are notably rarer, and they have the wonderful feature of an enclosed mechanism, so that in the event of failure, they are unlikely to result in damage to the rest of the differential and bearings.
      The later 2-pinion gov-locks found in newer trucks -that resemble the infamous 10-bolt gov lock carriers - are much more failure prone, I will not even try to disagree on that.
      I am not citing anecdotal evidence, as it is unreliable for debates but I, personally, have had several 2500 suburbans and pickups with the conical gov-locks, and have severely beaten all of them wheeling through mud and virtually every surface and incline- albeit with stock-ish tires and factory motors- and they have functioned without complaint. I’ve had old motor and transmission mounts rip out from the engagement shock while hammering over steep muddy hills in RWD, but the locker held fast.
      I do believe that the biggest issues were corner-cutting the original design, and simultaneously downsizing the proven mechanism to fit smaller differentials.
      In short, not all Gov-Locks are created equal.

    When I purchased my New Used 2001 GMC Yukon XL 4x4 about 12 years ago the G80 in it was making noise, it had 245000 miles on it this was the only thing wrong. I called the only Axle rebuilder in my area he refused to work on it and said the G80 was Junk!! I just got a whole Axle from a Junkyard I put another 100000 on it since no issues! He lost money and my business. I know these Eaton Axles are great. No you can't abuse them by doing burnouts but if you treat them as intended they will last a long time. Don't let anyone tell you they are Junk if they do they are probably just jealous because they are a Ford Fanboy maybe Dodge. Neither have anything like this! I'm not against Dodge I have a Ram 2500 with a 6.7 Cummins. If that truck ever gets damaged I'll find a way to drop that Cummins in a Chevy lol that will be the best truck ever.

    The good old G-80 Grenade-Loc differential... They're not a fan of oversized tires and if you have one to not punch it to get it to lock... If you have stock tires and you ease into the gas and wait for it to lock they work really well.

    Many refer to the Eaton Locker as "the G80" or vice versa but GM's code G80 (Positraction) may mean either limited slip differential or Torsen differential or this Eaton Locker. It depends on the vehicle's production year and model.

    i'm confused as to why the truck with the limited slip failed to make the ramp. where both rear tires not spining? why does my 454 camaro not over power the stock limited slip? both tires spin like crazy. they must be using a worn limited slip. i have owned many limited slip diffs lot of old chevys over the years and except for the ones that were worn i always spun both rear tires- even when i didn't want to. i like the gov lock because it will 1 wheel a little bit. also i believe the G80 isn't just gov loc it's the S.P.I.D. code meaning you have some type of limited slip differetial not necessarily a gov loc.

    • @SuperTurbocoupe
      @SuperTurbocoupe  3 роки тому

      It's widely acknowledged that limited slips that use clutches are known to one wheel under load, especially when one has very little traction and the other has normal or high traction. It's quite common. As far as your comment regarding the RPO code G80, what's your point? Nobody says it's for gov-loc only.

    • @Sherman62
      @Sherman62 Рік тому

      Yeah, I've had a few Eaton clutch Positraction units and they worked very well. 12 bolt and 10 bolt street cars. They were old when I got them and never wore out. I understand that the clutches can wear out but it must take extreme use.
      The Posi and the "Gov-Loc" are somewhat similar. They both use clutch plates to lock the diff, but the Posi uses the torque applied to the rear end to lock, while the Gov-Loc is activated by slippage. When my Silverado was new, the first time the Gov locked, it was harsh and sounded like a big wrench hit the driveshaft. Clang. It is not as bad now but still not as smooth as a Posi.
      The Posi locks by torque. Torque compresses the clutches via the bevel of the side gears. The more torque is applied, the tighter it locks. Sometimes you have to work the brakes to build enough torque to start the locking. I suspect this indicates worn clutches.

    wait, it this actually a G80?
    because i have never noticed a G80 ever working this correctly, this consistently.
    i recently drove onto a large ice puddle, in 4x4, in my 04 Z71 (so it does have a G80 locker); and only one rear tire would drive.
    it was really funny to watch. eventually, after sawing the wheels lock to lock it clawed itself across the ice; back to earth.
    but i think the only way to drive both rear tires dependably** (and by extension the front tires when the transfer case is in 4x4) is with a rear (air, or electronic solenoid activated) locker.... or maybe a torsion Gleason true trac.
    (unless stuff from Detroit was simply made better BEFORE they got a bailout)

      A limited slip will not perform the same as the locking differential. Limited slips work best in performance cars on asphalt where both wheels have the same traction. I put a limited slip in my 89 Blazer and it was just as worthless a an open diff in the snow.

    • @jessewoody5772
      @jessewoody5772 4 роки тому

      The LSD and the Govloc both attempt to bias torque to the tire with more traction. These two differentials go about it in completely different ways.
      The posi being an LSD uses clutch packs to attempt to transfer torque to the traction side. The Govloc uses a rotating governor to totally lock the axleshafts together.
      Therefore the govloc can actually transfer 100% of available torque to one tire or the other.
      The posi can only transfer the amout of torque thats required to spin the least tractive tire plus the bias ratio caused by the clutchpacks.
      They both have their issues but both are worth having.....in the right vehicle and type of usage.

    • @jessewoody5772
      @jessewoody5772 4 роки тому

      This, from a JEEP forum:
      Torque?
      There is one phenomenon that we are not accounting for here: Torque cannot exist without resistance. If an engine can produce 240 lbs/ft it does not mean that it always is. If you were to place the whole jeep on blocks and place it in drive you will only have the amount of torque necessary to rotate the mass(drivetrain, tires) . Thats why on a Dyno there are rollers that apply "resistance" and then you can measure the amount of resistance that can be overcome(Torque). Don't confuse rotational speed as being the same thing. On an open diff,lets say one wheel on glare ice, the other on dry pavement- both wheels will see the same amount of torque. If it only requires 15 lbs/ft to spin the tire on ice, the tire that is not spinning is also receiving 15 lbs/ft, even though it may look like its doing nothing it is applying effort to the ground. Although it is likely no wheres near enough to move the vehicle. When you apply some amount of additional resistance to the spinning tire(LSD, BLD) the non spinning tire will receive a commensurate amount of torque and hopefully be enough to move the vehicle. If its an LSD it may still not be enough. The BLD can completely stop the spinning tire if needed and send enough torque to propel the vehicle
      GreenMachine13s explanation is accurate in stating how the torque "NEED" plays out.
      I guess you can tell we are all loving our Jeeps. :awesome
