How does a disassembly of a GM differential work?
Once the axle shafts have been removed, you can lift the ring gear and carrier out of the center section. Then the carrier disassembly can commence. Although other components do not have to be aligned, you need to keep the inner pinion bearing properly aligned. This bearing is pressed on and removing the bearing instantly changes alignment.
How does clutch lock out inter axle differential?
To lock out inter-axle differential action, the clutch engages the helical-side gear and causes this gear, the input shaft and differential to rotate as one assembly. This action provides a positive drive to both axles. With Lockout engaged, torque is distributed to both-axles without differential action.
How does the pinion gear work on a GM differential?
In both units the pinion gear uses a crush sleeve to set the preload on the bearings and removing it requires the installation of a new crush sleeve. So, consider this fair warning. Once the axle shafts have been removed, you can lift the ring gear and carrier out of the center section. Then the carrier disassembly can commence.
How can you tell if a Chevy differential is worn?
Try to lift the wheels to determine if there is any movement in the axle. There should be very little. If the wheel moves up and down, the axle bearings are most likely worn or failing. Also check the pinion yoke with the same test, after unbolting the U-joint.
What kind of rear differential does GM use?
The only Dana I know that GM used in a rear application was the Dana 60 in some of the 3/4 ton vans a while back. Until they switched to IFS, they used the D44 (later replaced by the Corp 10-bolt) and D60 for the front axle. This 10.5 is what i know as a “Corporate 14-bolt”, and its design has been in use by GM since the late 60s/early 70s.
How much fluid to change in rear differential?

How big of a differential do I Need?
The following are recommended Differential Set-Up Specifications for various differentials. If in doubt, consult our staff of differential parts specialists. 8″ Front / Rear – 4 Cyl.
How does a rear differential lubricant system work?
However, the way a differential lubrication system works is that the ring gear slings the lubricant up into the front of the housing to flood the pinion bearings. So if its a little over filled, its not going to know the difference (think about running on a side hill, up or down a steep hill, etc…the level is always changing anyway.
What’s the first step in disassembling a Chevy?
The first step is to suspend the chassis and let the rear extend freely under the car. Use the properly rated floor jack to jack up the car and place the correct jackstands under the frame rails. Remove the lug nuts and take off the rear wheels. The shocks are fully extended and can be unbolted.

What is the GM RPO code for rear axle?
(Accurate identification using the GM RPO code assumes that the rear end has not been previously modified) The prefix is usually F, G or H when referring to Axle Identification. The list below is a partial list of typical GM RPO Codes, specifically the codes pertaining to Axle Identification, Differential Type and Gear Ratio.
