Having installed the system several years ago, and paying close attention to installing the grease hole in the bolt in a horizontal position, I've begun to have difficulty in greasing the bolts that mount to the hangars. Even after removing the tire, and unloading the axle the grease would not easily flow, in fact two of the four bolts were dysfunctional.
While installing new bronze bushings, it became apparent that the eye hole in the leaf spring had become out of round. After the new bushing was pressed in, the bolt would not easily slide through it, and it too had to be pressed in as well. Even with this new bushing the grease will not flow. I did check the bolts, and the pathway for the grease was clear.
During the initial installation, this problem did not exist, and I'm trying to understand as to how the leaf spring eye could become elongated, and how to best remedy the problem?
