How to install a Chevy axle assembly and differential?
The only differences are a few of the settings specs, which vary by version and year. You start the procedure by setting pinion depth. You should begin by using the stock shim when installing a new pinion gear. Use a caliper micrometer to measure the width of the shims.
What kind of axle does a GMC rear axle have?
A rear axle is designated ad Hypoid or Spiral Bevel according to the type of gearing used. Hypoid axles have drive pinion offset in respect to the centerline of the ring gear. Spiral Bevel axles have the drive pinion on center with the ring gear.
Do you have to re-assembly a differential carrier?
If you are reusing the same ring and pinion gears and differential carrier, re-assembly is relatively simple because the mesh pattern does not have to be reset so the shims remain the same. Nothing really moves. If you’re replacing the ring or pinion gears or the differential carrier, you have to start from the beginning for gear mesh and depth.

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 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.
Do you have to change bearing when disassembling differential?
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. Don’t remove the bearing unless you are replacing it.
What happens when rear axle bearings go bad?
When rear axle bearings go bad they normally make a grinding or whining noise and occasionally leak oil onto the tire and brake assembly. Replacing the rear axle bearings is somewhat of a technical job.
