FILL the pot of this coupler with grease; thereis NO such thing as too much, here. The shoes go on with the curved side to the shaft, and so there is the least amount of slop in the coupler. Bending the tabs over is usually the hardest part of this job, and a large pair of channel-lock pliers is a great boon. Also, as Chrycostated, be certain that you assemble it to the steering gear correctly, as well.
