Limited Slip Rpo G80 Troubles

[scooter88]

Hey everyone..thought maybe someone could help me out. I have a 04 GMC 5.3l ECSB 2WD with intake,exhaust,tune,vette servo and shift kit amid other minor mods..Glove box says it has a RPO code of G80 which is the limited slip differential. Way i member it it used to nearly always or fair amount of the time lock up if i turned to the drivers side and got on it an almost always if i took off straight line or power braked. Didnt always seem to lock up turning right for some reason. Now just recently its been giving stress as straight line it seems to only be spinning passenger rear tire if i punch it from stop or power brake. Any one have any ideas whats wrong? Havnt heard any unusual noises from it lately that i can remember..thanks

First off its a locker not a limited slip. See this bullitan from GM...

 

LOCKING DIFFERENTIAL LUBRICANT (SERVICE INFORMATION) #91-4-109

SUBJECT: LOCKING DIFFERENTIAL (G80) LUBRICANT - (SERVICE INFORMATION)

VEHICLES AFFECTED: ALL LIGHT TRUCKS EQUIPPED WITH G80 REAR AXLE ALL YEARS

Some light duty trucks equipped with locking rear axles (G80) may exhibit rear axle chatter, especially when turning a corner from a stop.

This condition of alternate engagement and disengagement of clutches in differential assembly is usually caused by contaminated axle lubricant.

To correct this condition, drain and refill the rear axle with SAE 80W-90 GL5 (P/N 10950849). The use of any additive in locking rear axles (G80) is not recommended. Rear axle additives are designed for use in limited slip differentials which are normally installed in cars. All light duty trucks equipped with RPO G80 make use of a locking differential and the use of additives will delay the engagement of the locking mechanism and may decrease axle life.

VEHICLES/COMPONENTS INVOLVED: ----------------------------- Some light duty trucks equipped with locking rear axles, RPO G80.

SERVICE PARTS INFORMATION:

Part Number Description ----------- ------------------ 10950849 Lubricant, Rear Axle (1 litre)

Parts are currently available through CANSPO.

WARRANTY INFORMATION:

As specified in Light Duty Truck Maintenance Schedules, locking rear axle fluid drain and refill is required owner maintenance at the first engine oil change. Failure to drain and refill the rear axle as specified may contribute to a later axle chatter condition. Refer to the appropriate Light Duty Truck Maintenance Schedule or service manual, section OB, for further details on change intervals.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle.

Thanks...not sure this is my problem. The differential seems to work fine other than not locking up during wheelspin. It seemed to work mostly fine until a bit ago. But might not hurt to try!

[joutlaw]

Do you remember it get into a bind and then a popping sound? maybe while turning slowing into tight spot? A pin can shear and the lockup will not occur anymore. I think the same thing happened to mine and I'm going to change the diff fluid and look for metal fragments. It's best to get it out before it trashes the ring and pinion. Everything I've read is your diff will just act like a open carrier after this happens.

I believe your problem is punching it. The G80 locks if there is more than 100 rpm difference between the two rear wheels. It will not lock above 20 mph. If you punch it you can spin the one tire over 20mph before it has a chance to lock. The G80 is to keep you from getting stuck. Any one who has been stuck knows you don't punch it to get out. It works fine when used as designed. For other applications you need a more heavy duty locker.

I may be wrong, but if one wheel is spinning, the differential speed would be the average between the 2 wheel speeds, so in effect, one wheel would have to be going 40mph if the other is still at rest before the 20mph feature comes into play.

 

Based on 100rpm difference, that is approx 8-10 mph difference between wheels before the differential locks.

 

 

I would think that his locker is broken, based on the things he described.

[Prokopchuk_9]

G80 isnt a real "locker" anyways dude...its just worn out thats all...put a detroit in ur diff...thats a locker. im surprised you baggin ur truck like that it actually lasted. i blew mine real fast. on two trucks. detroit true trac is what im runnin now..wears the back tires a little faster but shit man at least it hooks up. dont get no **** a$$ one legged peel outs....

Speed has nothing to do with it. It is 100 rpm difference between the two wheels. You can be sitting still and spin the wheels and lock it. It will not not lock over 20 mph. It does lock both rear wheels together. It works real well for what GM desighed it to do. Get you unstuck at low speeds. It was never designed for racing.

 

But yeah he could have broken it.

[scooter88]

Yeah im afraid its broke also..maybe a pin sheared as stated in above post. Will have to look into it. Dont remember it makin a noise but could have missed it. I had the differential worked on when it had about 36k on it,actually i think it was totally rebuilt because if i remember correctly the bill was around $1700. Tho they got it covered under warranty. Just for interests sake,i gave the last 8 of my VIN to the dealer and he said it was a limited slip. If you go to the RPO code lookup under G80,this is what it comes up with.

sounds like the most common issue with those diffs, either they lock up solid or they dont lock at all...the only downfall with the gear type locker is that it is a little noisy when you are off the gas goin down a hill or something feathering the brake...but man since i put that locker in i can go waaaaaay further into SH*T than i ever did before just in 2 wheel drive...

That is kind of what I was saying

 

According to the You Tube Video that was posted explaining how the G80 worked, it will not lock until there is a 100rpm difference between the 2 axles. My point was that 100rpm is equal to 8 - 10 mph at the wheel. So by design, the locker will not lock until one wheel is going approx at least 8 mph faster than the other.

 

And with the placement of the pawl in the differential, it requires approx 20 mph differential speed to reach the point of non-engagement, which means if the Original Poster punched it, the tire that was spinning would have to reach at least 40mph without the other tire moving for the locker to not engage because of the top speed limitation of the feature. Either way, once the speedo reads 20 mph the feature is disengaged (not because of the speedo, but if the speedo reads 20 mph, then the differential is turning at a speed equal to 20 mph if both tires were equal)

 

I agree with what you said, and I think maybe you were thrown off by what I was trying to imply to the poster that said that the problem with his differential was the fact he was punching it.

Hey man sorry if i made you upset by my ignorance..understand what your saying now! Why the world would my VIN come up with a limited slip is what i cant understand but mayb the gm parts guy didnt know exactly what he was looking at..Thanks for your time.
