That is your rear axle. It delivers the power to your tires.
The locking differential came on some of them. To determine if a particular Blazer has a locking differential you need to look for code "G80" on the RPO list. The RPO list is on a sticker in the glove compartment.
80w-90
Sure... you pull out the axle shafts, and its disconnected.
The differential on a 1986 Silverado can be replaced with any year differential from 1973 to 1987. The replacement differential must be either a 2-wheel drive or a 4-wheel drive, depending on the type that needs to be replaced.
I have a 97 blazer and I had to go to a GM dealer to get the differential shift cable that connects the 4wd actuator to the vacuum actuator switch. Apparently a dealer is the only place you can purchase this part. Hope this helps.

The 04 requires a 75/90 Synthetic and the 96 users an 80/90 GL5. Using 80/90 GL5 on gears that require synthetic lubricants will ruin them. Your answer is no. Iron
No.
Yes you can. There the same. Just take the parts / sending unit out of the 1987 tank and install them in the 1986 tank.
I have a 2002 Blazer with the 4.3L engine and 3.73 differential gear ratio, it gives me 17 mpg on average.
For a 1996 Chevrolet Blazer, the recommended weight for rear differential gear oil is typically 75W-90. If the vehicle has a limited-slip differential, you may also need to add a friction modifier to ensure proper performance. Always check the owner's manual for specific recommendations and any manufacturer updates.
