Sqeaky Shocks
 

I own a 1999 4 cylinder grand am. My front shocks were replaced about 8 months ago when I snapped the spring going over a bump. At that time nothing was done to my rear shocks. Now I'm having a problem whenever I hit the gas from a dead stop or moderataly hit my brakes, or just barly push down on my car my rear shocks will squeak. I put some WD-40 in the joinst in the rear shocks and this help for a few mins, so I'm pretty sure it's a lubracation problem. Does anyone know what I should use to lubracate and where specificly I should spray? Thanks for the time
