Yamaha golf cart G2-G19, steering knuckle king pin & bushing repair

This old Yamaha G2 golf cart from the mid 1980’s had a clunky front suspension, as a result of failing wheel bearings and eroded king pins and king pin bushings.
This video is a fastener by fastener description of how to replace king pins and king pin bushings. The kit we used was made by Excaliber, STR-023, which on the label is said to be appropriate for Yamaha golf cart models G2, G3, G4, G5, G6, G7, G8, G9, G10, G11, G12, G13, G14, G15, G16, G17, G18, to G19. A similar kit is available on Amazon, and from other retailers. To determine your version, search for the vehicle serial number and then use a search engine to find websites that describe model names. From there you may be able to find a parts list and service manual.
