How do I know if I need to replace my front springs I replace my shocks on my 95

So same thing applies to springs as the shocks then the shocks were ok?because front-end is the same as before how do you know which ones need replaced or do you do both at same time every time

If u drive down the road and hit a bump and the car keeps bouncing forever u need Springs like a boat going over waves ...

My experience leads me to never just do one side. Do them both!....unless money really permits only one. Depending on where you live, pot holes and snow plowing patches out of pot holes etc.- tear up the passenger side first. A new single side replacement will more than likely just make the old side feel mushy and leave you with poor handling in steering or bounce type swaying in the rear. 3 Limos
