There are a lotta personal airplanes out there that could use some serious landing gear attention, doesn't matter which model.
Wiring harnesses, switches, missing boots, worn out attach bolts, worn bushings, corroded springs, corroded cables, corroded rod end bearings, gearboxes that haven't been serviced in decades, worn out electric motors, decades old hydraulic hoses, the list goes on and on.
Some just plain sloppy like a plastic spring guide in 210, that should have been replaced with a metal one, DECADES ago it was introduced.
The rod end bearing on the main gear actuator in the 177RG series, yes it been a known weak link for a long time, still finding orginal ones in these airplanes, typically after they fail. Seems like I read about it every year in the club forums when a member can't get the gear to extend and totals the airplane, for a rod end bearing...
