At 150k miles, original suspension components that may need newː
- control arms
- end links
- shocks and struts
Struts/dampers generally last around 70k. Control arms, ball joints, endlinks, and strut mounts? Maybe 100k if the roads are nice. So at 100k you should really be replacing almost anything.
Exceptions are lighter cars. The lighter the car, the longer everything lasts.
