ok i was out crawling underneath the front end and saw a hard plastic ring with a groove all the way around it in the middle. the ring was, forgive me for my terminology here was between the end of the axle and the u joints i believe, just hanging there it would spin in a circle freely. not sure how long its been like this. it is the same on both sides. any suggestions on what it is and what i have to do about it. thank you.

If you have ESOF, this seal is also a vacuum seal. A vacuum leak here can either keep the hubs from locking automatically, allow dirt and water to be drawn into the spindle bearing or both.

Replacing these seals is part of the spindle bearing service. The recommended service interval for these bearings can be found here
