1500 Silverado differential problem

- Silverado G80 differential locking mechanism problem occurs under 25 - 30 mph. Will post solution when solved, pretty sure its the locking mechanism.
I had no idea I'd have this many views and subscribers up to this point which is cool and thank you guys for taking interest in my video!
So I posted in the comments what the problem was but I'll write it up here too, it was the transfer! After all the troubleshooting I did with the diff the problem was fixed with an oil change to the transfer case. I replaced the diff with a limited slip type and problem still occurred. Then I remembered the service light for transfer was on but I ignore it! I didn't check out the transfer further then sold the truck, so my best guess is after lifting the truck for a tire change inclining the truck shifting the oil to one side with the transfer stationary, it shifted some components that were probably already worn causing them to go out of whack, causing this problem.

There's no load on the axle not spinning and when the lock engages it overspeeds the stationary wheel until the little bit of load there goes away at which point it unlocks. It's working fine 👍
Yes sir
Appreciate the video it shows a normally functioning GM Truck G80 locker rear differential. The pall just mechanically engages and makes a noise. A lot of problems with the G80 locker are caused by dirty oil. NOTE: DO NOT use the GM additive in the truck LOCKING axle the additive is only for the limited slip axles in the passenger cars. The additive can keep the lock clutches from engaging. Always interesting to see how things really work...
Darryl S so a normally functioning locker doesnt lock?
Rukkkis no it makes the noise when the diff is spinning at the same.position each time probably a bad piece of gear
That's is correct sir☺ just like it stated in the owners manual (1998 k1500 suburban & k1500 Silverado z71 both 5.7l VORTEC 4l60e both trucks no longer with the family 😭 scrap because of my father's passing)
The G80 diff is good. had one drop a few axle bearings after a few years of off-roading tho.
That gov lock is doing exactly what it's supposed to. If you watch the left axle isn't spinning and the right one is so the mechanism is trying to actuate the locker exactly as it's supposed to and they clunk when they engage. But you don't have it under enough load to keep it engaged so it's engaging and disengaging. I've had these diff's for years and even rebuilt them, there is nothing wrong in this video except the operator.
blk95gsrt I was in the Walmart parking lot and it felt as if my rear locker engaged and went to pull into a parking spot and I felt and could hear the drivers side tire skirting across the pavement like my locker was still locked any ideas on what could be wrong ?
Hard to say sounds like it engaged and hung for some reason. Start with the basics and change the fluid. The gov lock is a clutch type diff and if the fluid is in bad shape the clutches won't function properly. If that doesn't help you may have had a failure and you'll need to repair or replace the diff.
blk95gsrt replaced the fluid about two weeks works like brand new since thanks for your advice
No problem glad to help
blk95gsrt was driving today took a turn going maybe 5 mph and heard a loud boom like something snapped and I could tell my locker engaged again could this be because I hve 35” tires or is my locker just broken I just changed the gear fluid almost 2 months ago and I baby my truck it’s a parking lot princess
i've NEVER had a problem with any G80 - great units for me!
Yes they are when driven properly and not like a maniac or hotrodding
Thank you for the information and help I love this video 10000000/10 ❤❤❤❤❤❤❤❤❤❤
My '05 G80 broke in '06 and was completely changed out with a new unit.......I was told by the shop mgr....that the units containing some parts not of stainless steel was the issue.......don't know for sure however the replacement G80 has worked well since the shop replacement under warranty........ 13 years later.
I called Eaton who makes the G80. I was backing up in the grass on an incline and it went boom when it locked in. The guy told me it was totally normal. That G80 scares me!
Forgot about this video... in case n e one was curious it turned out to be the transfer. Needed an oil change.
jameslocke I thought you said this started happening after a fluid change.
Have you ever heard of one locking and unlocking own its own when your simply just driving down a level paved road at 30 to 50 mph? Once in a parking lot making a slow sharp turn the inside wheel started spinning just a tiny bit. I think it was locked at that time.
+jameslocke the transfer?
+Kirby from the research I've read, yes. it generally comes down to the locking mechanism being faulty.
+Archer69er yup, it needed an oil change badly... once I changed it the problem stopped. goes to show how IMPORTANT the fluids in your vehicle are
changed the oil in the transfer case? or changed the oil in the rear diff?
Lovely
Nice 👍👍
For the life of me I can’t understand why someone would think a ‘service fed system’ would automatically be a rear differential problem. That said, 35 inch tires will blow the G80’s apart. Significantly higher inertia than stock wheel/tire combination.
The pin with governor fly weight is bent or splines on pin is the problem.
Seems ok.
Reverse Governor falls open at bottom of rotation and jams. Missing spring action
I think this is my prob. But it catches on reverse sometimes never in forward.
its really a good idea to run that without oil
There's no load or any real speed involved. Won't do any harm.
Joshua Hatton it's not a good idea to run it with oil gear lube on the other hand. And yes I'm just being a smart-ass.
Na with this amount of load on the thing it's totally fine. Have you ever used a power drill or a drill press to drill through steel? Usually you lube up the bit and the punched hole you're about to drill into. If you keep the bit turning slow enough you'll never see a burn mark or smoke indicating heat scarred/weakened metal. Those gears look like they have plenty of lube on them for light rotations like this. That T-rex walking sound coming from the vehicle though.... now THAT sounds horrible.
If you're gonna beat on your truck,Gov-Loc might not hold up. Had one in my 2wd S10,it didn't hold up.
I didn't even beat on that truck. I didn't even take it off road or do burnouts with it. I towed a 1500lb boat & trailer. Some teeth broke off a little shaft inside. I put a Torsen in there out of a Camaro. Torsen is just as smooth and there's really nothing to break inside,no clutches to wear out. Got it used for $250.00.Another thing is that the clutches won't last the life of the vehicle with Gov-loc.They'll probably wear out by 100k. Clutches are worn out in my Explorer 8.8 trac-lok. It's got 150k on it but they been worn out for a long time. As long as you plan on keeping both tires on the ground I'd get a Torsen or a Tru-Track.
I have a major clunk noise as I accelerate in the rear of my 2008 and a ton of lateral play in the right rear hub. what is up with that?
there's going to be a very small amount of lateral play in the hub/axle shafts. the clunking noise is pretty serious. You can try doing an oil change if problem still occurs take it to a specialist.
Gm recommends synthetic fluid for rear diff .
....without additive, if its a limited slip then you can put in additives👍
@@brandedmcgowan9414 Its a g80... aka limited slip
@@KoaGuy that's a car g80 (or g86) lsd the trucks g80 is a true locking differential we had 3 GM trucks/suvs 2010 Tahoe 4x2 1998 burban 4x4 and 1500 z71 Silverado 4x4 that actually locks the axle without slippage to the tires tried it my self and does it job excellent✌
Koa limited slip has clutches. The additives are friction modifiers. Since the G80 is a locker, it doesn’t need friction modifiers. You are correct, is a type of LSD but they’re referring to a specific kind.
Most likely not the transfer or the differential. The problem is most likely the left rear brakes are dragging. It's a brake issue.
Hello thank you for a awesome video. I'm looking for some good advice here hopefully you or any of your commentators can assist me. I have a 05 chevy Tahoe LT,4x4. I believe it's got 3.72 gears. Lately my rear end seems to lock up when turning at slow speeds. And from time to time I may here a clunk as well when turning. I dont here any humming, grinding noise or winding noise. I opened up the cover and replaced the gear fluid with recommend 75-90. I did not see any scoring or anything on the gears from what I can see. When I inspected the cover I found a small piece of curved metal about the size of a quarter. It does not appear that it broke off of anything. It looks more like a retaining clip of some sort that may have loosened up and fall off. Not quite sure if this is what is causing my issue. Additionally when driving straight on street or highway i get the feeling the feeling of dragging or pulling a heavy trailer. The power just isn't there. Please help!!! Thank you for your input
Perhaps your C clip fell out
@@TheGermtheman No. My issue was not the C clips. It was one of the small retaining clips which hold the spider gears together. That is was started it all.
@@TheGermtheman thank you for your reply. I have since replaced the G80 case. All is good now.
My 01 Silverado did this especially when backing into a turn situation. Thought my differential was binding up. Turns out it was a caliper hanging up.
I have a 2004 Silverado 1500 that is making a humming / vibrating noise when accelerating I was wondering if it is the differential .
Same problem, where you able to detect the problem or solve it.
♥️👍
Is that a Eaton g80 locking ?
sir im gonna ask . wen i shift to hi gear the low RPM my truck have an vibration and noise . i dont now wer it come .. can you help me
Joel Juntilla. did you figure it out? vibration in rear usually be a driveshaft the yokes would be out of phase. I hope you have already addressed this issue. If so let me know if I'm wrong please
I have the same problem on my 2007 Silverado. Did you ever figure out the problem. It’s driving me crazy.
My 14 Silverado does a weird noise clunking sound when backing up only any idea????
Probably leaf springs
how do you know if you have this rear end or the other rear end that has them spider gears
Look in your dash box and look for the codes gu6 gt4 gt5 and g80 ( im missing a few codes) but those numbers in the dash box have a purpose
What ratio is the deferential??
when you drove the truck did it crackle and sound like something rattling in the rear end? @james
it didn't crackle it just did as it shows in the video but not as loud.
+jameslocke because on my 02 silverado when I drive but around second gear it's makes like a cracking noise like yours but louder, you can only hear it when you roll down your windows. but as soon as it does it you can let off the gas and it will stop.
+jameslocke do you think it could be the rear diff or transfer case
+Michael Strait it can be a similar problem to mine which was in the transfer. it only need an oil change. check / replace fluids see if it improves. inspect your entire drive line for obvious damage. if problem continues you need to take her to a specialist my friend.
+jameslocke I'm going to open the rear diff tomorrow, and inspect ever thing and do an oil change on it and see if that does anything
its working as designed
Behold the amazing GM exploding differential
Known as "The Gov Bomb". We throw them in the scrap pile all the time, they get replaced with an Eaton/Detroit Truetrac.
Not aure the problem, but thanks for the vid o of the diff working
Thank you for your video. Would you be able to guide me with this issue I'm having. I have a 05 chevy tahoe, 3.42 gears. GU6,G80. lately when I turn in either direction at slow speeds, my rear wheels start to lock up and drag as if I was braking but I'm not. I am also starting to hear a growl when coming to slow stop. Any idea on what can be causing this issue and how to remedy. It's my daily driver and need it back on the road. I am also running 37" tires. Your input or advice will be greatly appreciated. Thank you
Hello I’m having the same issue, how did you fix yours
@@cesarhernandez6852 I change the gear case. Itvwas hard work let me tell you, but I did it in 3 days in my back yard. Turns out one of the retaining clips which hold the spider gears in place felt out. This caused a catastrophic failure inside the diferential case. I kept driving like that for a while until one of the spider gears broke some teeth and the whole case cracked.
@@cesarhernandez6852 I was lucky that the pinion gear and my ring gear did not sustained any damage and I was able to reuse them
@@cesarhernandez6852 u can find use gear cases in Amazon, ebay or facebook market. Just make sure there the same gear ratio. Mines was 3.42. Code GU6
@@cesarhernandez6852 the second option would be to just replace the whole rear end.
My problem is it acts like its locked all the time hard turn it starts jerking like its in 4x4
I have a 2003 gmc sierra denali, when I start the engine and put the truck on drive or reverse without pressing the gas and turning the wheel a little bit it start making a noise and you can hear the entire truck vibrating like something is hitting on the differential. Just changed the entire front suspension and replaced the steering wheel bearing but after a month in the shop and all those parts, still do the same noise. Anyone can point me in the right direction of what can be causing this?
Joel López Torres u joints
It's the slip joint in the steering shaft, they all do it
Had a '16 Silverado, rear end and air conditioner went out before 40,000 miles. Then had a '18 Silverado, ruined two front tires because of alinement issue, $950 for smog system all before 25,000 miles. Now driving a tundra.
my 2000 silverado 1500 rear differential Just fully locked about a week ago even idling in a parking lot and turning the inside tire is chirping and locked up. almost wonder if changing the fluid would help. kind of doubt it. has anyone else had that issue? Also made a popping noise twice this morning.
@@murdershewrote9890 I haven’t. It’s definitely starting to pop pretty bad. Haven’t been driving it as much.
Wow u are almost describing my same issue. Mine is not lock up completely that I can't drive it but just feels like if I was dragging a heavy load and it was slowing me down. Like when pulling a trailer. When turning at slow speeds in either direccion, I hear my back tires dragging as if I was breaking but I am not. I have had some popping noise as well. I change the diff fluid yesterday. I found a piece of metal on the cover it looks like a retaining clip of some sort. It does not look broken or anything. May have fallen off but not sure. Not even sure if it's part of hole thing. I wonder if the shop I had it at a few years ago when I replaced the axles shaft and bearings forgot this piece and it just got stuck to the magnet on the cover. Anyways Please help!! any advise would be helpful and very appreciated. In your case was it the transfer case fluid??? Gonna look into that next. I have 145k Miles on the truck.
@@murdershewrote9890 and yes. That is exactly what happened to me. When I opened up the differential cover I saw a large crank on the case. Also some of the teeth on one of the spider gears had broken off. When I finally pull out the case the entire thing literally broke in two pieces. Wish I can post the pics here. I replaced the case with a used unit and I was able to reused my original pinion gear and ring gear. I was lucky that those two didn't sustain any damage.
riders did u fix it?? Was it cracked???
The gears looked like a bomb went off lol. Ended up putting 4.88 gears and a trutrack in it.
spider gear are broken
Put mine in the shop today. It was making a noise jut like a whining child, just like a whining child. Wally took the cover of the gear box, took one look at her and closed her back up again
What was it?
I have the same problem
@@mitchellking3861 gear itself
@@smug8567 i am aware of six gears in there, was it all of them that was bad?
@@jasonbrown467 Turns out yes
My brand new silverado with only 4,000 miles on it clunks a lot it's actually annoying and the dealer never looked at it they just said it's a normal sound
Johnny G it’s normal if u have a G80 locker
Only 4,000 miles? Mine has 200k miles its a 2014 cero issues.
any point to this?
Lol not anymore... just thought it was interesting and kept it up. sorry if it disappointed
jameslocke I'm trying to figure outwhy it does it. Did yoyfigure out why?
+Richard Mann specifically I don't know... All I know it was a slippage inside the transfercase... I replaced the differential and it still did that. that's what pointed me down the line of the power train which next in line was the transfer... after being positive that the drive shafts and u joints were good.
typical g80
I have codes on my dash because of a wheel sensor i have the G80 Diff but if i completely disable stabilitrak and traction it wont slide the diff will open especially on corners, it’s difficult to get it to lock anyone know about this??
My 05 diff decided to just fall apart at 145k my 5.3L had no problem shearing and grinding gms governor into itty bitty peices. From falling apart viewpoint my new aftermarket clutch pack gearset ought to last much longer. I couldnt beleive all the small parts that made up this OEM diff they were definitly the weak link that killed it.
This is why I bought a Silverado with open diff, I have grenaded these before
BadAssEngineering you can get an open differential?
On Mexico, with the entry level silverados, yeah, and in the US I suppose you can spec the G80 out
Geez. I'm just gonna fit a Ford 9 to mine. What a POS.
I can see left sife broken teeth
The newer that G M trucks get the junkier they get . I had a 1991-1500 Chevy , the best truck I ever owned . Finally wore it out . My truck now is a 1993 -1500 Chevy pu and in just 2 years , it has several new features different from the 1991 that are as sorry and junkie as you can get . These companies today have engineers that are as sorry as you can get . A CHILD COULD PROBABLY COME UP WITH BETTER STUFF !!!!!!!!!!!!!!!!!!!!!!!!!!! They are either to dumb or trying to get an attaboy biscuit from the company they work for to produce anything worthwhile . Most companies have brought shame and reproach on themselves and on those that work for them , all in the name of profits and planned obsolescence !!!!!!!!!!!!!!!!!!

These dif suck bad and crack...chevy is using the same dif in camaros and putting them in their trucks...I converted mine over to posi
After seeing all issues with Silverado rethinking of buying an ford or Toyota
jamrs pancurak your are a smart a man buying Toyotas tundra with peace mind my 2007 tundra crewmax with 166000 miles still drive like the first day i bought it 11 15 2007 is the best truck money can buy or go with f150 5.0
Have you tried a bike ?
The toyata tundra is a chevy knockoff. It sits on a GM frame, hosts the lower end of the chevy 5.7 motor.
That doesnt have these issues. So that means its not the components but the company.
icewolf1988 and Chevy the cheap knock-off of Ford.
Still wont buy a ford
eaton lockers are useless . replace with a auburn limited slip or a lock rite locker.
Say what? my Suburban with G80 differential has 180,000 miles on it and no issues?
Limited slip...lol
These rear ends are trash.
So bought a 2021 custom trail boss and at 12,000 miles my rear differential needs to be replaced. Filed claim with corporate and so did my local dealership. Never towed or went off road with truck. Now I don’t even want this truck. They should put me in a new one. Truck Ian paid off and I couldn’t trade it in with this history now. Pissed!!!!!!!😡😡😡😡
