I have a 1996 Saturn SW2.
When I turn hard left at a bit of speed (like about 20 mph), the left read end of my car makes a BOING sound… what could be causing this??
Probably a broken spring. Have a trusted local mechanic take a look at it. Find one near you in the “Mechanics Files” section of this site.
+1 to jesmed.
The last “boing” sound I heard was a broken coil spring. The only way to find out is to take it to a mechanic.
