For me replaceable wear parts on my vehicle with 80-100K miles on them don't owe me anything and are probably, in my humble opinion, near end of life.
Examples for me are: belts, hoses, water pump, thermostat, alternator, idlers, pulleys, tensioners, shocks, struts, brake pads, ball joints, rotors, bushings, CV joints/boots/axles and such. Essentially anything on the front of the motor that turns or carries fluid and the working suspension components.
I take a "Touch It Once" attitude when I am refurbishing an area.
I am currently in the starting phase of a rear suspension makeover (front makeover was last month at 100K) replacing shocks, upper arms, ball joints, subframe bushings, CV axles, shock mounts, and lower control arm bushings.
The pressure difference to compress the new KYB shock and the Factory 2002/100K mile shock is significant.
If budget and time allows, you will appreciate not having to go back into an area to replace old components that "looked" OK when you did the broken/failed one
IMHO, those struts have given above and beyond the call of duty.
