I am going to replace the differential pig with a new one. Trying to decide what brand and type of to get. Have a 83/4 rear end. Going to put 3.91 gears in it. I am understand one model of the Auburn will wear out and a different won't. Also have read where some are louder than others. Have read Richmond gears are louder. Of course I am wanting something quiet but will hold up. May run on the strip a couple times a year. Mostly just crusing around town. Are some smoother than others. Other than reading their ads, I don't known anything about this. Appreciate any advice.
