How long do they last? Once again depending on how you use your car, now to give you an idea on their lifespan, let's use my car as an example (A 93 Honda Civic), i treat her better than my girlfirend and my self so my bushings and ball joints last for more than 30k miles. I think it's even more because i can't remember the last time i replaced them.

Yes

radiator fan assembly on those cars go bad frequently.
but i can't offer any more information beyond that.
