Last holidays set about changing front struts in my corona (had been sold wrong ones and thus put on after springs and rear items). When we pulled the front struts out they were well and truly fused in and once loosen revealed the original oiled filled struts. This is on a car that reads 406000kms on the clock.
My question is any had shocks on longer than that.
Replaced springs that were original to pretty shithouse after that distance.
I just refitted most of the steering and suspension hardware in my TA22. The rear dampers were Toyota (Tokico) OEM parts.
Presuming that...
A) the original dampers would've lasted at least 10 years, and
B) that nobody in their right mind buys factory OEM dampers for ten-year-old plus cars
...then I conclude that the dampers were still the factory original items. Working on a presumed 20,000km/yr, those dampers were over 600,000km old. Yes, they were rooted.
