Overview
The Dana Spicer 550759 is an inner spindle bearing sold as an OE replacement part. It is the inner bearing for the spindle position, not the outer one.
Match the bearing to your axle’s dimensions rather than relying on a model name.
Inner bearing basics
Inner spindle bearings carry much of the load that the hub passes into the spindle, so a worn one often shows up as a grinding or rumbling noise that changes with speed. Heat at the hub after a drive and play when the wheel is rocked by hand are other signs. Inner and outer bearings wear differently, so inspect both positions when one is failing.
When replacing an inner bearing, check the race and the spindle surface for scoring, and clean the hub thoroughly before pressing in the new part. Use fresh grease and keep dust out of the assembly. Replace the seal at the same time when the hub is opened, and confirm the size before buying rather than relying on a model name.
