Once the stock slider was removed, Howard cleaned out the old, hard stock grease by wiping the rack and moving it back and forth. If the old grease is really bad, the rack could be disassembled and repacked with the silicone grease.
Here is the rack, nice and clean and ready to install the new slider.
Next, Howard applies the silicone grease to the SHG slider and the rack.
The metal inserts that the bracket bolts tighten against are pushed into the new slider. The SHG slider is reinstalled and the boot slipped back over it.
The metal inserts in the rack slider are re-indexed with the holes in the rubber boot.
