How do install the sleeves? I put them on the linkage and tried to pull them in by tightening, but they got stuck. Now I'm trying to put the sleeve into the knuckle first, but am having a hard time. Any tips would be greatly appreciated.

The sleeves are designed to be used in F150 or 78-79 knuckles with the larger taper. They should just slip into the knuckle, and be held in place by tightening you 67-75 size ball joint. If the taper is not large enough, you can ream to size with our #2385.
