The TA Performance differential girdle is a well engineered unit that preloads and adds strength to the bearing caps. Not only does it help keep them from flexing under heavy loads, it provides convenient fill and drain plugs as well. The heat dissipating properties of this unit also helps to reduce its operating temperatures. The installation only requires few hand tools and it can be accomplished in a relatively short amount of time. I have documented my recent experience here and I hope that you will find it useful. Please note that this will specifically discuss an installation for a GM 10 bolt. TA Performance markets this unit for multiple applications and your installation procedures may slightly differ. Always refer to the included instructions that will come with your specific application. For more information, please refer to their website at www.TAPerformance.com.

To begin my installation, I have first removed only the top five bolts from the cover. While using a 5/16-18 tap, I cleaned out the threads to ensure that the proper amount of torque is achieved during the reinstallation process. Doing this before removing the remaining bolts will help prevent unwanted trash from entering the inside. A 3/8 drive 1/4 8pt socket and swivel head ratchet was used for ease and accessibility reasons.

After partially reinstalling the top bolt so that the cover does not fall into the pan, I removed the remaining bolts to complete the thread cleaning proceedure.

I then used a screwdriver and soft mallet to wedge the cover loose and drain the old gear oil.

After inspecting the ring gear for unusual wear, I began the process of carefully scraping away the old gasket material. Reaching into the bottom of the pumpkin and feeling around is a good way to search for signs of broken debris. After slowly pulling out as much of the oil as possible, I sprayed down the insides with brake cleaner because I will now be using a synthetic oil. For my application I also selected the optional ARP replacement cap studs. It is only $20.00 more with the purchase of their rear cover. These will provide additional insurance to prevent the caps from walking under heavy loads.
