Last week my the rear suspension on my car started to squeak really bad. It has always squeaked a lil when I went over a huge bump but it has been lowered and I have heard that that sometimes happens when you lower your car. This was terrible though. A few days ago I jacked my car up and sprayed some silicon lubricant on the spring and around the top and bottom of the spring and on the rubber peices that the springs rest on. This helped the problem a lil bit but im still not satisfied. Do any of yall have any suggestions?

 

rubber isolators, or poly urethane isolators and plenty of grease (cause poly squeaks anyway).

 

try sum oil
