Jackie,

If this is what you are referring to, you have to open up the ball/bell/cover, slide it rearwards, and disconnect the u-joint.

Then, remove the rear yoke for the u-joint,
remove the seal/rings,
clean all parts/surfaces,
put the rear cap on/over torque-tube,
and put the tin-seal-ring in place.

Before to put anything back together, read and follow the instructions in the shop manual regarding how to determine how many paper sell-rings you need to seal the bell/ball/cover.
