Does a G80 require friction modifier?
G80’s do NOT use a Friction Modifier additive like most other limited slip or “posi” rear ends.
Can I pump out rear differential fluid?
If your differential has both a drain plug and a fill plug your first step is to remove the two plugs with your ratchet and socket. In some models, there’s only one plug, and the old fluid must be drawn out with a hand pump. Once the fluid is drained, if your drain plug has a crush washer, replace it with a new one.
What are the symptoms of low rear differential fluid?
What are the Symptoms of Bad Differential/Gear Oil?
- Burning Smell from the Differential. When you notice a bad smell coming from your gearbox, you should take it as a sign of bad differential oil which can be contaminated hence not operating as it should be.
- Weird Noises.
- Vibrations.
Does a G80 have clutches?
MLocker (G80) Operation The stopped flyweight triggers a self-energizing clutch system, forcing a cam plate to ramp against a side gear. Cam plate ramping will continue to increase until both axles turn at the same speed (full lock), which prevents further wheel slip.
Does changing differential fluid make a difference?
In most cases, you will need to change differential fluid every 30,000 to 50,000 miles. It’s important to stay on top of changing differential fluid because metal-on-metal contact creates heat from friction. It also weakens gears and wears down surfaces. That can lead to differential failure, which is a costly problem.
Is it bad to overfill differential?
No, it’s really hard to overfill a differential with oil to cause a failure.
Is the GM G80 considered a limited slip?
Absolutely not,The G80 is not considered a limited-slip (Although some limited slip action occurs) its a locker. From SI in the GM service manual (And this might be more info. than you want,but never the less)…..
What kind of lube do you use on a Chevy G80?
The G80 calls for syn. GL-5, 75W-90 gear lube. (You can also use 75W-90 in the front diff.) The reason GM says don’t add LS additive on a G80 is because, most ALL GL-5 gear lubes (the G80 uses a GL-5 syn gear lube) contain some amount of LS/FM additive, thats pre-mixed in each bottle. The amount thats pre-mixed wont harm the G80.
What does the RPO G80 rear differential do?
The optional locking differential (RPO G80) enhances the traction capability of the rear axle by combining the characteristics of a limited-slip differential and the ability of the axle shafts to “lock” together when uneven traction surfaces exist. The differential accomplishes this in 2 ways.
Do you need to use an additive with the G80?
You’re not supposed to use an additive with the G80. +1 DO NOT use any additive. New fasteners/bolts is not necessary. You’re not supposed to use an additive with the G80. +1 DO NOT use any additive. New fasteners/bolts is not necessary.
