You can do it for far less, with better materials. The Chevy 10-bolt differential is the most popular automotive rear-end second only to the Chevy 12-bolt. If you have a limited slip with a clutch pack in the carrier use a limited slip gear lube or straight gear lube with a bottle of limited slip additive. I asked my local dealer service manager about this issue this morning over coffee: he claims it makes servicing easier! That meant we needed new axles. From 2002 on same with front axle, synthetic 75W-90 is required.
On this swap, we did this about 15 times, for various reasons. Built from the 1970s through today the 8. The most typical breakdowns of the rear end is the wheel bearings. I was looking between 2 different brands: mobil 1 synthetic, and valvoline synthetic. Next the contact pattern must be checked, which is done with colored grease included as part of the new gear install kit. Keep doing this until the magnet stays clean, then refill with your gear oil of choice. I also have my moms car on it.
Geez, why do we always post out of synch? You could always take a picture of your bottles label and send it to the manufacture for clarification. Since they require a synthetic 75W-90 gear oil, that stuff is very stable and has little expansion under heat. One bottle of this and it was still making some noise but after a week it was gone completely. I'm at 157,000 right now, with the original transfer case fluid. It has to be drained to get a peak inside.
The differential carrier holds the ring gear and connects the pinion gear to the rear axles. That way there is no guessing if there is enough oil in it or not. It is a design characteristic of these steel clutch plates to exhibit more clutch chatter than other models. This one spins both wheels under power, unlike the open-style off on the right. Quadrasteer vehicles use Dana axles and have a different fluid requirement. I might check the service manual on this.
I want my 10 bolt to last as long as possible, but it will be replaced eventually. Keeping the axle topped off will keep the pinion bearing immersed in gear oil. For sure take off the rear diff. I recommend full synthetic lubes, and personally believe Amsoil will give you the best protection. It's enough to make most guys gag. I have touched the brakes lightly to stop the wheelspin,and it will lock right up. You have to remove the rear cover on the differential housing.
Some folks may wonder about seal leaks run this way. My last truck had the same statement in the owners manual, and as soon as I changed fluid the diff started chattering feels like two blocks of rubber slipping past one another. I think I will have the rear differential oil changed at the dealer, but skip the rest since I only use the 4 wheel drive to be sure it still works maybe once a month on gravel or snow. After 25 mph is will not lock. At least my autotac did.
Drain rear differential by removing the cover. Tighten the bolts in a crosswise pattern. Swapping gears is not that difficult, but it takes time to learn the process and a lot of trial and error. They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. This link to the procedures are great.
Note: you may want to take the rear cover off the axle to clean the magnets off. If it ain't right, don't do it. An aluminum cover is three times as good heat dissipator as the sheet metal cover, especially when it has fins on it. Note that these differential covers have an O-ring seal, which requires no sealant and is the best possible design available, a magnetic drain plug, and oil dipstick, and also a temperature sender port if you want to wire a differential oil temperature sender with a gauge. Next time I will change my differential oil, I'll put 2 of these for a complete oil change in my differential. The gear oil can be easily changed by following the Chevy 10-bolt procedure. I am buying at the gm parts department.
It has been now about 200 miles since and I could hardly notice any more differential groaning noise. Most rear ends use these to hold the axles in place. The front axle drain plug has a magnet on it, and I bet it will be full of black sludge and heavy filings. To get the rear set up properly, you will need some tools — specifically, a and some. His career began in the car audio industry as a shop manager, eventually working his way into a position at Rockford Fosgate as a product designer. Remove bearing, a slide hammer style puller may be needed to remove bearing. Different additives can accomplish the same function and still not have deterimental effect on the lockers.
