How To Repack a H233B Limited-Slip Differential (LSD)
This is for anyone wanting to “repack” their H233B clutch-based limited-slip differential (LSD). It applies to C200 and H190A LSDs, too. It does not apply to other Nissan/Infiniti RWD/AWD diffs, such as the viscous LSD in R200V. It won’t cover the specific how-to’s of differential removal, setup, or installation, but will cover the basic assembly process. (I’ll answer any questions related to those topics, though.) All specific information (instructions, service data, torque specs, etc.) is
Technical Objective
The purpose of repacking is to increase the breakaway torque of the LSD, or the amount of torque required to rotate one side gear while the other remains stationary.
I will use the following codes and symbols to describe stack configurations:
This picture shows two different configurations:
The top stack will be described as “5FD, 6FP, 2SS” and conveyed as:
