Spool Installation
The Dana 60 in this Jeep had been built with 35-spline shafts. On this vehicle it borders on overkill. Some believe a spool will decrease the stress placed on the shafts, especially on the street. The occasional jerk and bang from an automatic locker can fatigue axleshafts. Others feel that the constant twisting stress of a spool is more likely to snap a shaft. Small shafts with low spline counts and spools (or lockers) don’t mix well. If your vehicle is a heavyweight, has lots of horsepower, or is abused regularly, consider upgrading the shafts at the same time. View Related Article
