How often should I have my suspension checked?
I give mine at least a quick visual every time I change the oil.
If you are not mechanically inclined, your car should have a good inspection every year by a experienced mechanic. A good time to have that inspection is when brake work is done. I would also have an inspection if I’m going on a trip farther than 500 miles from home.
Those who do not have regular inspections are the people that complain that their mechanic found $2000 worth of work. A regular inspection can space those projects out to make it easier on the wallet.
