The gear overhaul is a service instruction or service letter,the gear does not need overhauling after 5yrs.
A lot of these SL/SI depend on the aircraft useage & cater for the worst case scenario i.e flown out of bush strips in africa!!!for general use then this will not need to be done.
Just inspect the swivel joints & retraction jacks for leaks & excessive wear.
Get them to print you off the 182RG Maintenance schedule with time life components.
The gear is not on there,you will find the seatbelts/static lines/vac pump/engine hoses/prop govenor etc are.Am doing this from memory so sorry if I have missed an item.
Have just been involved in an ARC renewal on a 182RG.
Lycoming also recomend the engine is overhauled at 12years so are your maintenance company going to make you do this if your engine is 12years old?I suggest you argue this case to save any uneccessary expenses on your part .Good Luck
