This is a frustrating topic for our technicians. I think that the problem stems from the glacially slow pace that shocks and struts wear out. The loss of function takes so long that many drivers don’t notice it.
When our techs recommend new shocks or struts, based on performance loss, oil leakage, tire wear, or anything else, some people are surprised – but then when they get the car back, they can’t believe how nicely it rides and handles!
It’s uncommon for someone to ask about suspension on their own – it’s more common for shock/strut replacement to be a result of a “noise-over-bumps” complaint.
