I'm in the process of tearing down a 23-2 differential. My concern is the backlash. Before pulling it apart the backlash measured .024. this appears to be excessive. This is my first differential rebuild and I want it back together correctly for obvious reasons. I haven't pulled the bearings yet so not sure what shim dims are yet. Question, when putting it back together should I attempt to adjust the shims to tighten the backlash to the correct spec or start with the original configuration? Spec is .002 -.009. Thanks in advance for any information.
